Description

The present invention relates to a sound-absorbing transmission-type earplug suitable for a hearing impaired person.

In general, earplugs are used in places where noise is generated, such as factories and road construction sites, in order to reduce the burden on the ears and seek sound and sound insulation effects.

  However, for hearing-impaired people, if the hearing ability of low-frequency and medium-frequency sounds is lower than the voices that they listen to in daily life, the sounds of turning newspapers, and the sounds of opening and closing doors, it is normal for high-frequency sounds. Even when maintaining a good level of hearing, due to hearing loss, high-frequency sounds can be heard as if they were cracked, or they can be heard with discomfort as if the sound squeezed into the body. There was a problem that the drug had to be taken.

  Also, in hearing tests, normal hearing is confirmed for all low-frequency sounds, medium-frequency sounds, and high-frequency sounds, and even if no abnormalities are diagnosed in the eardrum, Low-frequency / medium-frequency sound that uses compressors and home appliances as sound source enters the ear through the external auditory canal as air vibrations from the outer ear, generates sound pressure, and can be heard roughly, or if it deteriorates further, the sound source cannot be identified I hear it. As a symptom at this time, it is thought that the bone part and eardrum of the ear canal are closed, and since the sensitivity near the frequency that resonates as a resonator is increased, the sound resonates and inflammation occurs at the boundary between the cartilage part and the bone part of the ear canal Cause pain, and pain continues. However, since the relationship between low-frequency noise and the effects on the human body is not well known, the treatment is routine, such as the application of steroid ointment, as in the case of temporary external ear canalitis caused by wounds or bacteria. There was a problem that we had to take a method that was said to be undesirable.

In view of the above problems, the present invention uses the earplugs for high frequency sound countermeasures, low frequency sound / medium frequency sound countermeasures, and low frequency sound / medium frequency sound / high frequency sound countermeasures having a sound absorbing function. It is an object of the present invention to provide three types of sound-absorbing transmission-type earplugs that do not require any medication or application, and that can reproduce and listen to natural soft sounds.

In order to solve the above-mentioned problem, the sound-absorbing transmitted-tone earplug according to claim 1 is a fine-sponge with good skin and a little tension so that the outer ear hole of a person's ear is not burdened. in order to have a little formed into the shape of the larger similarity than the ear hole, which was the ear hole sponge, the ear hole sponge is inserted and held in the cartilage of the ear hole, the hole opened to the outside of the ear hole and a portion pinna lead regarded as an ear hole end, shaping the end face facing the outside of the ear hole sponge and its end so as to be a shape of the same surface, also in contact with this surface, ear hole end In order to avoid interference with the part where the auricle is connected to the end of the ear canal, excellent rubber plate wear resistance by forming a sound absorbing plate a as a countermeasure, the the said sound absorbing plate a A material obtained by partial and combined adhesive in contact with the end face of the same shape and surface facing the outside of the ear hole sponge and earplugs, the earplugs of the sound by plugging a hole in which the sound absorbing plate A is opened to the outside of the ear It is characterized by being configured to prevent diffraction.

Absorbing type transmission sound type earplug of claim 2, wherein instead of the sound absorbing plate A in absorbing type transmission sound type earplug of claim 1, since the sound absorption is also influenced by the frequency band, low-frequency sound, the rubber plate elastic excellent as a measure medium frequency sound produced in the same manner as the sound absorbing plate a sound-absorbing plate B, the a pre-Symbol acoustical panel B ear hole sponge molding and bonding in claim 1 and the same methods An earplug is used as the earplug, and the earplug is configured such that the sound absorbing plate B can prevent sound diffraction by closing a hole opened outside the ear.

Absorbing type transmission sound type earplug of claim 3 is the external auditory pore sponge and the sound absorbing plate A · said sound absorbing plate B in the sound absorption type transmission sound type earplug of claim 1 and claim 2, firstly the the sound absorbing plate a and the sound absorbing plate B was bonded together in the same shape and surface, this as a sound absorbing plate C measures the low frequency sound, medium frequency sound-high frequency sound, face and this was the sound absorbing plate B side The end plug facing the outside of the outer ear hole sponge is bonded in the same shape and surface to make an ear plug, and the ear plug has a sound by closing the hole opened by the sound absorbing plate C to the outside of the ear. It is characterized in that it can be prevented from diffraction.

The present invention has the following effects.
According to the sound-absorbing transmission-type earplug according to claim 1, since the outer ear canal sponge uses a fine, fine-grained sponge and has a shape similar to that of the outer ear canal. There is no sense of incongruity or pressure as if I put it in, and I can hardly feel the feeling of insertion as an insertion part of the same earplug into the outer ear hole.

Further, the earplugs because blocking the ear acoustical panel A, the moisture such as sweat loving in the ear ear hole sponge can be absorbed.

  In addition, since the sound absorbing plate A has a notch, it is easy to distinguish the left and right earplugs from each other, and the earplugs can be easily inserted into the outer ear hole.

  Further, since the sound absorbing plate A can block a hole opened outside the ear, sound diffraction can be prevented. Therefore, external sound can be heard through the sound absorbing plate A and only transmitted sound can be heard through the ear canal.

  In addition, since a rubber plate with excellent wear resistance is used as the sound absorbing plate A as a measure against high frequency sound, when the sound wave energy of the high frequency sound comes into contact with the sound absorbing plate A, the sound is converted into thermal energy and reverberates. It can be reduced and the original natural soft sound can be reproduced as the transmitted sound.

  As a result, the high frequency sound does not sound as if it was broken, or the sound does not feel uncomfortable as if it crawls on the body, so the use of a tranquilizer is also unnecessary.

  According to the sound-absorbing transmission-type earplug according to claim 2, the sound-absorbing plate B has a notch, so that it is easy to distinguish between the left and right earplugs and to the outer ear hole of the earplugs. It is easy to insert according to the shape.

  Further, since the sound absorbing plate B can block a hole opened outside the ear, sound diffraction can be prevented. Therefore, only the transmitted sound can be heard through the external auditory canal through the sound absorbing plate B.

  In addition, since a rubber plate with excellent elasticity is used as the sound absorbing plate B as a countermeasure against low frequency sound and medium frequency sound, the energy of the sound waves of the low frequency sound and medium frequency sound is absorbed and decomposed by the sound absorbing plate B, and the sound is It is converted into thermal energy to reduce reverberation, and the original natural soft sound can be reproduced as transmitted sound.

This eliminates the noise that can be heard roughly so that the sound source cannot be identified, thus eliminating the inflammation and tingling pain that occurred in the ear canal. It becomes useless.

  According to the sound-absorbing transmission-type earplug according to claim 3, since the sound absorbing plate C has a notch, it is easy to distinguish between the left and right earplugs and to the outer ear hole of the same earplug. It is easy to insert according to the shape.

  In addition, the sound absorbing plate C can block a hole opened outside the ear, so that sound diffraction can be prevented. Therefore, only the transmitted sound can be heard through the external auditory canal through the sound absorbing plate C.

  Further, since the sound absorbing plate C used as a countermeasure against low frequency sound / medium frequency sound / high frequency sound is composed of the sound absorbing plate A according to claim 1 and the sound absorbing plate B according to claim 2, the energy of sound waves is reduced. It is contacted, absorbed and decomposed, and the sound is converted into thermal energy to reduce reverberation, and the original natural soft sound can be reproduced as transmitted sound.

  This makes it possible to naturally approach various sound sources that are difficult to approach physiologically in daily life.
