Description

TARIFNAME ISITME CIHAZI AYARLAMA VE BELIRLEMEYE YÖNELIK BIR SIMÜLASYON SISTEMI Teknolojik Alan: Bulus, hastanelerde isitme cihazi deneme ve ayari, isitme cihazi merkezlerinde isitme cihazi deneme ve ayari, rehabilitasyon merkezlerinde isitsel terapi üzerine tüm uygulamalarda kullanilmaya uygun bir simülasyon sistemidir. Bu bulus, dünyada en yaygin hastaliklardan biri olan isitme kaybi sonucunda kullanicilarin kullandigi isitme cihazlarinin, kullanicilara farkli ortamlarda denetilerek ayarlanmasini saglayan bir simülasyon sistemi ile ilgilidir. Teknigin Bilinen Durumu: Dünya saglik örgütünün verilerine göre isitme kaybi dünyanin en yaygin saglik problemlerinden biridir. Ve yillar geçtikçe sayisi artmaktadir. Isitme kayipli bireyler isitme kayiplarinin güncel hayatlarini etkilememesi için bu durumu kontrol altinda tutmak için isitme cihazi kullanmaktadirlar. Isitme cihazlari elektronik birer saglik aleti olup frekansa özel olarak ve yazilimsal olarak hastaya özel bir sekilde ayarlanabilmektedir. Bu ayarlar yapilirken kullanilan yöntemler tutarsiz kisiden kisiye degisebilmekte ve dogrulugu kontrol edilemeyecek haldedir. Bulusa konu sistem bu karisikligi ortadan kaldirmak üzere ortaya koyulmustur. Bilinen teknikte kullanilan geleneksel ayarlama yönteminde, sessiz bir ortamda hastaya sözel iletisimle soru cevap üzerinden ayar yapilmaktadir. Ayni zamanda el çirpma, masaya vurmak gibi sesler çikarilarak hastanin duyup duymadigi tespit edilmektedir. Bu yöntem kesin sonuçlar vermeyecegi gibi dogru sonuçlar da vermemektedir. Bu durum hastalarin yanlis ayarli veya yanlis tip isitme cihazlari kullanmalarina sebebiyet vermektedir. Bilinen teknikte kullanilan bir diger yöntem olan REM (Real Ear Measurement) sayesinde cihazdan verilen kazancin hastanin kulagina gerçekten gidip gitmedigi ölçülebilmektedir. Gerçek kulak ölçümü, isitme cihazi takildiginda hastanin kulak kanalinda olusan ses basinç seviyesinin ölçümüdür. Kulak disinda bir mikrofona bagli kanala yerlestirilmis bir silikon prob tüpü kullanilarak ölçülür ve isitme cihazinin hastanin isitme kaybi için uygun amplifikasyon sagladigini dogrulamak için yapilir. Gerçek kulak ölçümü ölçüm yaparken veri olarak isitme testini kullanir ve bunun sonucunda objektif bir dogrulama yaptigini iddia eder. Fakat isitme testi hastaya yollanan sesler dogrultusunda hastasini butona basmasiyla isaretlendigi için bu test sübjektiftir. Yani yine REM de objektif bir isitme cihazi ayari sonucu verememektedir. Bu yöntem ne kadar gerçege en yakin ayarlama olarak gözükse de laboratuvar ortaminda, her parametre devreye katilmadan hesaplanmistir. Gürültü ortamlarda ya da yeni kullanmaya baslamis hastalarda memnuniyetsizliklere sebebiyet vermektedir. Bilinen teknikte siklikla karsilasilan problemler asagida siralanmistir. 0 En büyük problemlerden biri hastanin verdigi geri dönüslerin dogrulugunun ya da yapilan ayarini dogrulugunun ölçülememesidir. 0 Bir diger problem, hastalara isitme cihazi merkezinde sessiz ve konusmanin anlasilir oldugu bir ortamda ayar yapilmasidir. Gerçek hayattaki ortamlar o kadar sessiz ve az kisili degildir. Çok sayida farkli gürültü etkeni bulunur. Hastanin kulagindaki isitme cihazi bu etkenlerin tamamina göre ayar gerektirebilmektedir. o Cihazi ayarlayan uzmanin problemi çözecek bilgiye sahip olamamasi, kisiye göre tutarsiz olmasi. Bu konuya örnek verilmesi gerekirse, hastanin tabak çanak seslerinden rahatsiz oldugu bir vakada, uzman bu seslerin kaç desibel ve frekansta oldugunu bilmiyorsa yanlis bölgeleri ayarlayabilir. o Hastalara uygulanan isitme cihazinin özelliklerinin ve segmentler arasi farklarin objektif gösterilememesi (gürültü baskilama, konusma iyilestirme ve benzeri) bir diger problem olarak göze çarpmaktadir. 0 Geleneksel metotlarin kisinin deneyimi ve becerisine göre çok degiskenlik göstermesi yine önemli bir problemdir. Uygulayici ne kadar deneyimli olsa bile yaptigi ayar dünyanin herhangi bir yerinde tutarli olmayacaktir. Hatta ayni ayari kendisinden yapmasini istesek kendisi bile yapamayacaktir. o REM yöntemi ne kadar gerçege en yakin ayarlama olarak gözükse de laboratuvar ortaminda, her parametre devreye katilmadan hesaplanmistir. Gürültü ortamlarda ya da yeni kullanmaya baslamis hastalarda memnuniyetsizlik sebebiyet verir. 0 Tüm yöntemlerde de hastanin fonemleri duyup duymadigi ve ya ayirt edip edemedigi tespit edilememektedir. Yalnizca tüm bu ayarlamalardan sonra serbest alan testi ya da kortikal test gibi yöntemlerle desteklenebilmektedir. o Sorulan sorular fonem dagilimi düsünmeden sorulmaktadir. Örnegin sesim sana nasil gelmekte sorusuna verilecek cevap ile etkin bir ayar yapilabilmesi mümkün degildir. Sorulan sorunun fonem (harflerin ses haline verilen ad) dagilimi incelendiginde her bölgeden fonem bulunmaktadir. Alinan cevaba göre hangi bölgeye ayar yapilacagi açik degildir. Yukaridaki sebeplerden ötürü, soru sormak yerine direkt frekansa spesifik bir ayarlama yöntemine ihtiyaç bulunmaktadir. dokümaninda satis magazasini ziyaret etmeden kullaniciya göre bir isitme cihazinin islevini uygun sekilde uydurabilen bir isitme cihazi ayarlama sistemi tarif edilmektedir. Tarif edilen sistem, kullanici bilgisinin bir veritabanindan çekilerek, eski kullandigi cihaz ile eslestirilmesi üzerinedir. Tarifnameye konu bulusta yer alan simülasyon sistemi bahsedilen Japonya patent dokümaninda yer almamaktadir. Literatür arastirmasinda mevcut bulustaki gibi gerçek ses ortamlarini kullaniciya simüle eden ve bu simülasyon ile frekans ayari yaparak uygun isitme cihazi ve ayarini tespit eden bir sisteme rastlanmamistir. Sonuç olarak teknigin bilinen durumunun asildigi ve dezavantajlarinin giderildigi yeni bir sisteme ihtiyaç duyulmaktadir. Bulusun Kisa Açiklanmasi: Bulus, isitme cihazi seçimi ve ayarinin yapilabilmesine yönelik teknigin bilinen durumunun asildigi, dezavantajlarinin giderildigi, ilave olarak ekstra avantajlar içeren bir simülasyon sistemidir. Bulusun amaci, farkli frekans araliklarindaki gerçek sesleri hastalara simüle ederek isitme cihazi seçimi ve ayarlarini yapabilmeyi saglayan bir simülasyon sistemi ortaya koymaktir. Bulusun bir diger amaci, hastalarin optimum derecede uygun isitme cihazi modelini ve ayarina erisebilmelerini saglamaktir. Bulusun bir diger amaci, isitme rahatsizliginin hastalara etkisini minimum seviyeye indirmektir. Bulusun bir diger amaci kesin, tutarli ve dogru bir isitme cihazi ayarlama ve belirleme sistemi ortaya koymaktir. Bulusa konu sistem sayesinde; 0 Geleneksel ve REM gibi ne kadar dogru olsa da tutarsiz ve uygulanabilirligi düsük yöntemlerin dezavantajlarinin, o Odyologlarin uzmanlik derecelerine göre degisken ayar yapilmasinin, Hastalarin pazarlamasi yapilan cihaz özelliklerini objektif görememesinin, Ayarlamanin sadece bir ortam üzerinde ayar yapilip diger ortamlarda sikintilarin devam etmesinden kaynakli problemlerin, Ayarlama hatalari yüzünden hastalarin isitme cihazlari hakkinda olusan negatif düsüncelerin, Pediatrik ve sürekli kontrol edilmesi gereken hasta gruplarinda (meniere, isitsel nöropati, ani isitme kaybi ve benzeri) sadece isitme cihazinin algoritmasina güvenilmesinden kaynakli sorunlarin, Çocuk isitme cihazi ayarinin rastgele yapilmasindan kaynakli problemlerin (iki kulagin birbirine esitlenmemesi lokalizasyon çalisilmamasi, fark etme ayirt etme ve tanimlama ses çalismalari yapilmamasi ve benzeri) önüne geçilmektedir. le birlikte; Farkli frekans ses degerlerine sahip farkli ortamlara uygun bir sekilde isitme cihazi seçimi ve ayari yapilabilmekte, Cihazli ve cihazsiz isitme esikleri belirlenebilmekte, Farkli desibellerde fonem ayirt etme testleri ve rahatsizlik testleri yapilabilmekte, Bilateral kullanimda sag ve sol kulak esitleme imkani saglanabilmekte, 360 derece her türlü ses ortami simüle edilebilmekte, (kafe, vapur, kalabalik konusma, toplanti, konser, sinema, tiyatro ve benzeri) MPO ayarlama, yer yön tayini testleri, gürültüde SRT SDS ayarlari yapilabilmekte, Hikayeyi anlama testleri yapilabilmekte, Ojektif pediatrik ayar yapilabilmekte Binlerce ses dosyasi ile sonsuz ayar imkani sunulabilmektedir. ile birlikte hastalarin isitme cihazlarini, ayarlayan kisiye bagli olmadan, tamda ayarlanmis tüm seslerle denemis bir sekilde sosyal hayatinda kullanmasi saglanmis, hastalarin cihazdan memnuniyeti en üst seviyeye çikarilmis ve isitme sagligini korunarak ilerlemesi engellenmistir. Sekillerin Açiklanmasi: Bulus, ilisikteki sekillere atifta bulunularak anlatilacaktir, böylece bulusun özellikleri daha net anlasilacaktir. Ancak, bunun amaci bulusu bu belli düzenlemeler ile sinirlamak degildir. Tam aksine, bulusun ilisikteki istemler tarafindan tanimlandigi alani içine dâhil edilebilecek bütün alternatif, degisiklik ve denkliklerinin kapsanmasi da amaçlanmistir. Gösterilen ayrintilar, sadece mevcut bulusun tercih edilen düzenlemelerinin anlatimi amaciyla gösterildigi ve hem yöntemlerin sekillendirilmesinin, hem de bulusun kurallari ve kavramsal özelliklerinin en kullanisli ve kolay anlasilir tanimini saglamak amaciyla sunulduklari anlasilmalidir. Bu çizimlerde; Sekil- 1 Bulus konusu simülasyon sistemini gösteren temsili görünüm. Bu bulusun anlasilmasina yardimci olacak sekiller ekli resimde belirtildigi gibi numaralandirilmis olup isimleri ile beraber asagida verilmistir. Referanslarin Açiklanmasi: . Islemci .Veritabani .Ses karti 40. Hoparlör 41.Gövde 50. Kablo Bulusun Açiklanmasi: Bu detayli açiklamada bulus konusu simülasyon sistemi sadece konunun daha iyi anlasilmasina yönelik olarak, hiçbir sinirlayici etki olusturmayacak örneklerle açiklanmaktadir. Bulusa konu simülasyon sistemi, donanimsal olarak en az bir hoparlör (40), farkli frekans araliklarindaki ses dosyalarini içeren en az bir veritabani (20), ses dosyalarini hoparlörlere (40) aktaran en az bir ses karti (30), ses dosyalarini çalistiran en az bir islemci (10), ekipmanlar arasi ses ve veri iletisimini saglayan en az bir kablo (50) veya kablosuz iletisim modülü (bluetooth, WiFi ve benzeri) içermektedir. Ayrica bulusta bu donanimlari kontrol eden, seslerdeki frekans degerlerine göre isitme cihazinin ayarinin yapilabilmesini saglayan, daha önce bahsedilen islemciye (10) entegre çalisan en az bir yazilim bulunmaktadir. Bulus birbirinden farkli ses veya ortamlari hastalara simüle etmek üzere tasarlanmistir. Yazilim, ayrica ses dosyalarindaki desibel ve frekans araliklarina göre isitme cihazina uygun desibel ve frekans ayarinin yapilabilmesine olanak saglamaktadir. Bulusta hoparlör (40) sayisi en az bir adet olarak tanimlanmistir. Fakat hoparlör (40) sayisinin artirilmasi, örnegin sag, sol, ön ve arkada birer adet olmasi hastanin sesleri farkli açilarda, 360° alabilmesine, sonuç olarak simülasyonun etkin bir sekilde kullanilabilmesini saglayacaktir. Bu sebeple bulusta birden fazla hoparlör (40) kullanimi önerilmektedir. Bulusta hoparlörler (40) bir gövde (41) üzerine konumlandirilmistir. Bu gövde (41) hoparlör (40) yüksekligini asagi-yukari degistirmek üzere bir hareket mekanizmasi içermektedir. Gövdenin (41) boyunun degismesindeki amaç sesi, hastanin kulak seviyesine göre ayarlamaktir. Böylelikle hastalara yukaridan veya asagidan gelen seslerin simülasyonu yapilabilmektedir. Ayni zamanda hoparlör (40) ve gövde (41) baglantisi mafsalli baglanti olup, hoparlörlerin (40) üç farkli eksende 360° dönebilme kabiliyeti bulunmaktadir. Bu sayede farkli açilardan gelen seslerin simülasyonu yapilabilmektedir. Hoparlör (40) gövdesi (41) istege bagli olarak zemin bölümde tekerlek mekanizmasi içerebilecektir. Bu sayede hoparlörlerin (40) hastaya yakinlik ve uzakligi ayarlanabilecektir. Hoparlör (40) sayisinin birden fazla oldugu sistem tasariminda, hoparlörlerin (40) hepsi ayni anda çalistirilabilmektedir. Bu durumda 360° ses deneyimi yasatilabilmektedir. Ayrica hoparlörler (40) teker teker de çalistirilabilmektedir. Kullanicinin sag taraftan gelen sesleri sol tarafa veya ön taraftan gelen sesleri arka tarafa göre daha iyi veya daha kötü duymasi sorunlarinin önüne geçilebilmekte, farkli yönlerden gelen sesleri esitlenmesi saglanabilmektedir. Bulusta veritabani (20) içerisinde binlerce ses dosyasi bulunmaktadir. Bu ses dosyalarinin özelligi her birinin farkli frekans araligina hitap etmesidir. Bilindigi üzere her bir sesin frekans araligi birbirinden farklidir. Çatal, biçak sesinin frekansi ile köpek havlamasinin frekansi birbirinden farklidir. Bu sebeple veritabani (20) içerisindeki ses kayitlarindan farkli frekansa sahip sesler hastalara dinletilerek sesleri ne denli duyup duymadiginin tespiti yapilir. Sesler farkli frekans araliklarina sahip ses dosyalarindan seçildiginde hastanin frekans sebepli isitme kayiplari varsa ayarlanabilir ve isitme cihazina optimum isitme ayari yapilabilir. Bulusta ses karti (30) veritabanindaki (20) seslerin hoparlörlere (40) aktarilmasini saglamaktadir. Üzerinde, sistemdeki hoparlör (40) sayisi kadar giris bulunmaktadir. Bulustaki islemci (10), seslerin oynatilabilecegi yazilimi bünyesinde barindirmaktadir. Bahsedilen islemci bir bilgisayar olabilmektedir. Programlari çalistirma görevi bulunmaktadir. Bulus ile fisiltida fonem ayirt etme islemi gerçeklestirilmektedir. Kelimelerin düsük desibeldeki fonemleri, yüksek desibeldeki fonemlerinden farklidir. Isitme cihazi kullanicisinin iki durumda da sesleri duyabilmesi ve karsi tarafi anlayabilmesi gerekmektedir. Bulusta ayni zamanda gürültülü ortamda fonem ayirt etme islemi yapilmaktadir. Gürültü ortamlar simülasyon sistemi ile simüle edilmekte ve hastanin sesleri ayirmasi ve karsi tarafi anlamasi gerekmektedir. Isitme cihazi frekans ayarlarinda buna uygun ayarlama yapilarak sorun giderilmektedir. Bulusta sag kulak ve sol kulak esitleme yapilmaktadir. Sag ve sol kulak esitleme farkli yönlerdeki hoparlörlerden (40) verilen seslerin kontrolü ile saglanmaktadir. Bilindigi üzere her kelimenin ses frekansi farklidir. Hastalar spesifik olarak bazi kelime veya harfleri duyamadigindan sikayet edebilmektedir. Bu durum yine veritabanindaki (20) farkli frekansli ses dosyalarinin simülasyonda kullanilmasi ile analiz edilebilmektedir. Bulusta gürültü kontrolleri yapilabilmektedir. Gürültü kontrolü, kafe ortami, konser ortami, toplanti ortami, sessiz ortam, havuz ortami, deniz ortami gibi ortamlarin simüle edilmesi saglanmaktadir. Bu ortam sesleri hastalara birebir simüle edilebilmektedir. Bulusta, hastanin herhangi bir sikayeti olmasa dahi, farkli frekans araliklarindaki kelime, ses veya ortamlara simüle edilerek hastaya dinletilir. Dinlediklerini duyup duymadigi, anlayip anlamadigi tespit edilerek isitme cihazlarina uygun frekans ayari yapilir. Bulusa konu sistemin kullanilmasi, isitme cihazi ayari için kullanan sistemlere göre tutarlilik ve bilimsel veriye uygunluk saglar. Verilen sesler tamami ile frekans ve desibelleri dikkate alinarak kayit edilmis ve tüm dünya için geçerliligi olan ses dosyalaridir. Hangi insan için hangi cihaz markasinda ayarlanirsa ayarlansin dogru ayarlama yapilmasini saglayacaktir. Bulusa konu simülasyon sistemi ayni zamanda rehabilitasyon uygulamalarinda kullanilabilmektedir. Isitme kayipli bireyler isitme kayiplari tanilandiktan ve gerekli tedavi ya da isitme cihazi ayarlama, koklear implant gibi çözümlerden sonra konusma ve dil edinimleri için devaminda isitsel rehabilitasyon egitimi almaktadirlar. Bu süreçte odyolog esliginde fark etme - ayirt etme- tanilama- yorumlama çalismalari veya daha detayli isitsel çalismalar yapilabilmektedir. Odyologun beceri ve deneyime göre degisiklik gösteren bu çalismalarda hastanin kaybina ve isitme kaybinin derecesine göre çalismalar degisebilmektedir. Odyolog çalismalar yaparken objektif sekilde sesini ya da frekanslari ayarlayamama ihtimalinden dolayi rehabilitasyon merkezlerinde de bu sistem objektif olarak farkli frekanslardaki ve desibellerdeki tüm dünya tarafindan kabul gören ses kayitlariyla bizler tarafindan düzenlenmis olan fark etme ayirt etme tanimlama yorumlama veya farkli isitsel terapi egitimlerini 360 derece her yönden uygulayarak rehabilitasyon çalismalari yapilabilir. Isitme kayipli bireyin rehabilitasyondaki isitsel gelisimi objektif olarak takip edilebilir. Sonuç olarak bulusta, en az bir hoparlör (40), farkli frekans araliklarindaki ses dosyalarini içeren en az bir veritabani (20), ses dosyalarini hoparlörlere (40) aktaran en az bir ses karti (30), ses dosyalarini çalistiran en az bir islemci (10), ekipmanlar arasi ses ve veri iletisimini saglayan en az bir kablo (50) veya kablosuz iletisim modülü (bluetooth, WiFi ve benzeri) kulak rehabilitasyonu çalisma ve egitimlerinde de kullanilabilir. Bulusta ses karti (30) harici olabilecegi gibi bir bilgisayarin içerisinde yer alan dahili bir ses karti (30) da olabilmektedir. Yine hoparlör (40) harici olarak düsünülse de bir bilgisayarin dahili hoparlörü (40) sistem içerisinde kullanilabilmektedir. Son olarak bulusa konu sistem içerisinde VR (Virtual Reality) sistemi entegre edilebilmektedir. VR sistemi rehabilitasyonda ve cihaz ayarlamasinda, hastalarin yeni geçilen ortama adaptasyonu konusunda, görsel uyaranla desteklenmesi adaptasyonunu ve canlandirmada görsel uyaran olmasinin pozitif etkisi olacaktir. Lokalizasyon becerisi içinde önemli olacaktir. Sistemde sesin geldigi taraf görsel uyaranla desteklenmektedir. Isitsel rehabilitasyonda kullanildiginda, giderek zorlastigi ve egitim sürecinde kisinin görsel pekistireç kullanmasi ses isitmesinin degerlendirilmesinde ekstra destek olmakta, gerçekçi bir simülasyon deneyimi yasatmaktadir. Ayni zamanda rehabilitasyonda kalinan süreçte görsel simülasyon hastanin sikilmasini da engellemektedir. TR TR TR TR TR TR TR TR TR TRDESCRIPTION OF A SIMULATION SYSTEM FOR HEARING AID ADJUSTMENT AND ASSESSMENT Technological Field: The invention is a simulation system suitable for use in all applications related to hearing aid trial and adjustment in hospitals, hearing aid trial and adjustment in hearing aid centers, and auditory therapy in rehabilitation centers. This invention relates to a simulation system that allows users to adjust their hearing aids in different environments, as a result of hearing loss, one of the most common diseases in the world. State of the Art: According to the World Health Organization, hearing loss is one of the most common health problems in the world, and its number is increasing year by year. Individuals with hearing loss use hearing aids to keep their hearing loss under control so that it does not affect their daily lives. Hearing aids are electronic medical devices that can be adjusted to a specific frequency and to the patient's individual needs via software. However, the methods used for these adjustments are inconsistent and vary from person to person, making it difficult to verify their accuracy. The system presented in this invention aims to eliminate this complexity. In the traditional adjustment method used in known techniques, adjustment is made through verbal communication with the patient in a quiet environment, using a question-and-answer format. Simultaneously, sounds such as clapping or tapping on a table are used to determine if the patient can hear. This method does not provide accurate or precise results, leading to patients using incorrectly adjusted or incorrect types of hearing aids. Another method used in known techniques, REM (Real Ear Measurement), allows for the measurement of whether the gain delivered by the device is actually reaching the patient's ear. Real ear hearing measurement is a measurement of the sound pressure level in the patient's ear canal when a hearing aid is fitted. It is measured using a silicone probe tube placed in the canal and connected to a microphone outside the ear. This measurement is performed to verify that the hearing aid provides adequate amplification for the patient's hearing loss. Real ear hearing measurement uses hearing tests as data and claims to provide objective verification. However, hearing tests are subjective because the patient signals by pressing a button based on the sounds sent to them. Therefore, it cannot provide an objective hearing aid adjustment result, even in REM sleep. Although this method appears to be the closest to reality, it is calculated in a laboratory setting without considering all parameters. It causes dissatisfaction in noisy environments or for patients who have recently started using hearing aids. Common problems encountered with this known technique are listed below. One of the biggest problems is the inability to measure the accuracy of patient feedback or the accuracy of the adjustments made. Another problem is that adjustments are made in a quiet and intelligible environment at the hearing aid center. Real-life environments are not so quiet and have fewer people. There are many different noise factors. The hearing aid in the patient's ear may need adjustment according to all of these factors. o The specialist adjusting the device may not have the knowledge to solve the problem, and the adjustments may be inconsistent depending on the individual. For example, in a case where the patient is bothered by the sound of plates and dishes, if the specialist does not know the decibel and frequency of these sounds, they may adjust the wrong areas. o The inability to objectively demonstrate the features of the hearing aid applied to patients and the differences between segments (noise suppression, speech enhancement, etc.) stands out as another problem. 0. The fact that traditional methods vary greatly depending on the individual's experience and skill is another significant problem. Even the most experienced practitioner's adjustments will not be consistent anywhere in the world. In fact, even if we asked them to make the same adjustment, they might not be able to. o Although the REM method appears to be the closest adjustment to reality, it is calculated in a laboratory setting without considering every parameter. It can cause dissatisfaction in noisy environments or with patients who are new to using it. 0. In all methods, it is not possible to determine whether the patient hears or distinguishes phonemes. It can only be supported by methods such as free-field testing or cortical testing after all these adjustments. o. The questions asked are without considering the phoneme distribution. For example, it is not possible to make an effective adjustment with the answer to the question "How does my voice sound to you?". When the phoneme distribution (the name given to the sound form of letters) of the question asked is examined, phonemes from every region are found. According to the answer received, it is unclear which region should be adjusted. For the reasons mentioned above, instead of asking a question, there is a need for a direct, frequency-specific adjustment method. The document describes a hearing aid adjustment system that can appropriately adapt the function of a hearing aid to the user without visiting a sales store. The described system is based on retrieving user information from a database and matching it with their previously used device. The simulation system included in the invention described is not included in the aforementioned Japanese patent document. In the literature search, no system similar to the current invention, which simulates real sound environments for the user and determines the appropriate hearing aid and adjustment by adjusting the frequency based on this simulation, has been found. As a result, a new system is needed that surpasses the known state of the art and eliminates its disadvantages. Brief Description of the Invention: The invention is a simulation system that surpasses the known state of the technology for selecting and adjusting hearing aids, eliminates its disadvantages, and includes additional advantages. The aim of the invention is to create a simulation system that enables patients to select and adjust hearing aids by simulating real sounds in different frequency ranges. Another aim of the invention is to ensure that patients can access the optimally suitable hearing aid model and setting. Another aim of the invention is to minimize the impact of hearing impairment on patients. The third aim of the invention is to create a precise, consistent, and accurate hearing aid adjustment and selection system. Thanks to the system described in the invention; 0. This prevents the disadvantages of traditional and REM methods, which, while accurate, are inconsistent and have low applicability; the variable adjustment based on the expertise of audiologists; patients' inability to objectively view the features of the devices being marketed; problems arising from adjustments being made only in one environment while difficulties persist in others; negative perceptions of hearing aids due to adjustment errors; problems arising from relying solely on the hearing aid algorithm in pediatric and patient groups requiring continuous monitoring (Meniere's disease, auditory neuropathy, sudden hearing loss, etc.); and problems arising from random adjustment of pediatric hearing aids (failure to equalize the two ears, failure to perform localization studies, failure to perform sound recognition, discrimination, and identification studies, etc.). Hearing aid selection and adjustment can be made to suit different environments with varying sound frequencies; hearing thresholds with and without aids can be determined; phoneme discrimination tests and discomfort tests can be performed at different decibel levels; right and left ear equalization is possible in bilateral use; 360-degree simulation of all kinds of sound environments (cafe, ferry, crowded conversation, meeting, concert, cinema, theater, etc.) can be performed; MPO adjustment, spatial orientation tests, and SRT SDS adjustments in noisy environments can be made; story comprehension tests can be performed; objective pediatric adjustment can be made; and endless adjustment possibilities are offered with thousands of sound files. With this, patients are enabled to use their hearing aids in their social lives, without being dependent on the person adjusting them, and with all the precisely adjusted sounds, maximizing patient satisfaction with the device and preventing the progression of hearing loss while preserving their hearing health. Explanation of Figures: The invention will be described by referring to the accompanying figures, so that the features of the invention can be understood more clearly. However, the aim is not to limit the invention to these specific arrangements. On the contrary, it is also intended to encompass all alternatives, modifications, and equivalencies that can be included within the scope of the invention as defined by the accompanying requirements.

Sound card 40. Speaker 41. Housing 50. Cable Description of the Invention: In this detailed description, the simulation system in question is explained with examples that will not create any limiting effect, only for the purpose of better understanding the subject. The simulation system described in the invention includes, as hardware, at least one loudspeaker (40), at least one database (20) containing audio files in different frequency ranges, at least one sound card (30) that transfers audio files to the loudspeakers (40), at least one processor (10) that plays the audio files, and at least one cable (50) or wireless communication module (bluetooth, WiFi, etc.) that provides audio and data communication between the equipment. Additionally, the invention includes at least one software integrated into the aforementioned processor (10) that controls this hardware and allows the hearing aid to be adjusted according to the frequency values in the audio. The invention is designed to simulate different sounds or environments for patients. The software also allows for the adjustment of the hearing aid to the appropriate decibel and frequency ranges according to the decibel and frequency ranges in the audio files. In the invention, the number of speakers (40) is defined as at least one. However, increasing the number of speakers (40), for example, one on the right, one on the left, one in front and one in the back, will allow the patient to receive sounds at different angles, 360°, and as a result, the simulation can be used effectively. For this reason, the use of more than one speaker (40) is recommended in the invention. In the invention, the speakers (40) are positioned on a body (41). This body (41) contains a movement mechanism to change the height of the speakers (40) up and down. The purpose of changing the height of the body (41) is to adjust the sound according to the patient's ear level. In this way, simulation of sounds coming from above or below can be performed for the patients. At the same time, the speaker (40) and the housing (41) are connected by an articulated connection, and the speakers (40) have the ability to rotate 360° on three different axes. This allows for the simulation of sounds coming from different angles. The speaker (40) housing (41) can optionally include a wheel mechanism in the base section. This allows the proximity and distance of the speakers (40) to the patient to be adjusted. In a system design with more than one speaker (40), all speakers (40) can be operated simultaneously. In this case, a 360° sound experience can be provided. In addition, the speakers (40) can be operated one by one. This prevents problems such as the user hearing sounds coming from the right side better or worse than those coming from the left or from the front, and ensures the equalization of sounds coming from different directions. The database (20) contains thousands of sound files. The characteristic of these sound files is that each one addresses a different frequency range. As is known, the frequency range of each sound is different from each other. The frequency of the sound of a fork and knife is different from the frequency of a dog barking. For this reason, sounds with different frequencies from the sound recordings in the database (20) are played to patients to determine how well they can hear the sounds. When sounds are selected from sound files with different frequency ranges, if the patient has frequency-related hearing loss, it can be adjusted and the optimum hearing setting can be made for the hearing aid. In the invention, the sound card (30) enables the transfer of sounds from the database (20) to the speakers (40). It has as many inputs as the number of speakers (40) in the system. The processor (10) in the invention contains the software that can play the sounds. The processor mentioned can be a computer. The task is to run the programs. The invention performs phoneme discrimination in whispers. The phonemes of words at low decibels are different from those at high decibels. The hearing aid user needs to be able to hear the sounds and understand the other party in both cases. The invention also performs phoneme discrimination in noisy environments. Noisy environments are simulated with a simulation system, and the patient needs to distinguish the sounds and understand the other party. The problem is solved by making appropriate adjustments in the hearing aid frequency settings. The invention performs right and left ear equalization. Right and left ear equalization is achieved by controlling the sounds given from speakers (40) in different directions. As is known, each word has a different sound frequency. Patients may complain that they cannot hear certain words or letters specifically. This situation can be analyzed by using (20) different frequency sound files in the database in the simulation. Noise control can be performed in the invention. Noise control enables the simulation of environments such as cafe environment, concert environment, meeting environment, quiet environment, pool environment, and sea environment. These environmental sounds can be simulated for patients. In the invention, even if the patient has no complaints, words, sounds or environments in different frequency ranges are simulated and played to the patient. Whether they hear and understand what they hear is determined, and the appropriate frequency setting is made for the hearing aids. The use of the system in question ensures consistency and conformity with scientific data compared to systems used for hearing aid adjustment. The sounds provided are sound files recorded taking into account their frequencies and decibels and are valid for the whole world. Regardless of the individual and the brand of device used, this system will ensure accurate adjustments. The simulation system discussed in this invention can also be used in rehabilitation applications. Individuals with hearing loss, after their hearing loss is diagnosed and necessary treatment or solutions such as hearing aid adjustment or cochlear implants are provided, receive auditory rehabilitation training for speech and language acquisition. In this process, recognition-discrimination-diagnosis-interpretation studies or more detailed auditory studies can be conducted with the assistance of an audiologist. These studies, which vary depending on the audiologist's skill and experience, can also change according to the patient's hearing loss and its degree. Because audiologists may not be able to objectively adjust the sound or frequencies during their studies, rehabilitation centers can utilize a system that objectively adapts sound recordings at different frequencies and decibels—recorded globally—to incorporate 360-degree, comprehensive training in hearing recognition, differentiation, identification, interpretation, and various auditory therapy techniques. This allows for objective monitoring of the auditory development of individuals with hearing loss during rehabilitation. In conclusion, the invention includes at least one speaker (40), at least one database (20) containing audio files in different frequency ranges, at least one sound card (30) that transfers audio files to the speakers (40), at least one processor (10) that plays the audio files, at least one cable (50) or wireless communication module (bluetooth, WiFi, etc.) that provides audio and data communication between equipment, and can also be used in ear rehabilitation studies and training. The sound card (30) in the invention can be external or an internal sound card (30) located inside a computer. Similarly, although the speaker (40) is considered external, an internal speaker (40) of a computer can be used within the system. Finally, a VR (Virtual Reality) system can be integrated into the system in question. In VR systems, during rehabilitation and device adjustment, the visual stimulation provided to support patients' adaptation to new environments will have a positive impact on adaptation and visual stimulation during simulation. It will also be important for localization skills. In the system, the side from which the sound is coming is supported by visual stimulation. When used in auditory rehabilitation, as the difficulty increases and the person uses visual reinforcement during the training process, it provides extra support in the evaluation of sound hearing and creates a realistic simulation experience. At the same time, visual simulation prevents the patient from getting bored during the rehabilitation process.
