In the following description, for purposes of explanation, specific details are set forth in order to provide a thorough understanding of the present invention. It is apparent that the invention is not limited to the specific details known to those skilled in the art. The following detailed description of preferred embodiments of the invention, however, the invention is capable of other embodiments in addition to those detailed.
It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of exemplary embodiments according to the invention. As used herein, the singular is intended to include the plural unless the context clearly dictates otherwise. It will be further understood that the terms "comprises" and/or "comprising," when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof.
Exemplary embodiments according to the present invention will now be described in more detail with reference to the accompanying drawings. These exemplary embodiments may, however, be embodied in many different forms and should not be construed as limited to only the embodiments set forth herein. It should be understood that these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of these exemplary embodiments to those skilled in the art. In the drawings, the same reference numerals are used to designate the same elements for the sake of simplicity, and thus their description will be omitted.
Embodiments of the present invention may be performed using a sound source localization test system. The sound source localization system comprises a sound feeding device. Preferably, the sound feeding means may comprise a first speaker and a second speaker. The first loudspeakers are all arranged on the same horizontal plane, and the second loudspeakers are arranged outside the horizontal plane where the first loudspeakers are located. In particular, the first speaker may comprise at least two speakers, and the at least two speakers are arranged at different positions in space to provide sound sources having different spatial positions. For example, at least two loudspeakers are arranged at different positions on the same horizontal plane. In this way, test conditions for completing the discrimination of different spatial positions of the sound source by the subject can be provided, so that the test of the sound source localization capability can be carried out.
Fig. 1 is a schematic flow chart of a method for testing sound source localization capability according to an embodiment of the present invention. A tester terminal, a subject terminal, and an acoustic device are shown in fig. 1. The method can comprise the following steps:
s1, sending a sound emission instruction to the sound emitting device to make the sound emitting device emit sound.
Illustratively, before S1, it may include: and realizing communication connection between the tester terminal and the sound giving device. Preferably, the tester terminal is in wired communication with the sound delivery device to reduce audio quality loss. For example, the tester terminal is connected to the sound feeding device through an audio cable.
As one example, the tester terminal establishes communication with each of the at least two speakers of the sound delivery device through the serial port. Each loudspeaker corresponds to one relay, and a plurality of relays form a control circuit. The common terminal of each relay is communicated with the serial port of the tester terminal, and the normally open contact of each relay is respectively communicated with each loudspeaker. When the tester terminal sends a sound-emitting instruction to the sound-emitting device, the corresponding relay responds to the sound-emitting instruction to close the normally open contact, so that the serial port of the tester terminal is communicated with the corresponding loudspeaker, and the corresponding loudspeaker emits sound according to expectation. It will be appreciated that the intensity, frequency, duration, etc. of the sound may be controlled by the sound emission instructions. Generally, in the embodiment of the present invention, the sound emitted from the speaker lasts for about 2s to 3 s. Preferably, the sound emitted by the speaker may simulate natural sounds such as thunder, bird, water flow, etc., or the sound emitted by the speaker may be pure tones, which may be selected according to the actual hearing conditions of the subject.
Illustratively, sending the voicing instruction to the voicing device includes sending the voicing instruction to a predetermined one of the first speakers. For example, a plurality of speakers are arranged around the subject, and the tester terminal may transmit a sound emission instruction to one of the plurality of speakers. Where "predetermined" means that which speaker is to sound is actually determined by the tester terminal. In other words, although the speaker that emits the sound may be randomly selected as any of the plurality of speakers, which speaker will emit the sound is objectively known to the tester terminal. Accordingly, the relevant parameters of the predetermined one of the loudspeakers are also known to the tester terminal.
S2, receiving input information from the terminal of the subject, the input information including position information of the sound input by the subject.
Illustratively, before S2, it may include: and realizing communication connection between the tester terminal and the subject terminal. Preferably, the tester terminal and the subject terminal are wirelessly communicatively connected to eliminate a distance restriction therebetween. For example, the connection is made wirelessly via communication means such as bluetooth, wireless fidelity (Wi-Fi), and the like. Because the distance limit between the tester terminal and the subject terminal is eliminated, the interference of the tester or other external factors on the subject can be avoided during the test process. Of course, the tester terminal and the subject terminal may be connected in wired communication, so that the signal transmission quality is higher and more stable.
Illustratively, the subject terminal may receive input information through an input interface, such as contactable by physical buttons, virtual buttons in a touchable screen, and the like. The mode is convenient and fast to operate. Alternatively, the subject terminal may receive input information in a non-contact manner such as voice input. The mode has wider applicable crowd range. The input information includes position information of a sound input by the subject. In particular, this refers to the relative position of the sound emitted by the speaker in spatial orientation as subjectively perceived by the subject, and not to the actual relative position of the sound in spatial orientation. Thus, the same sound emitted by the sound delivery device may correspond to different input information for different subjects.
S3, input information is processed.
Illustratively, in one example, the first speaker of the sound delivery device includes more than two speakers, the method includes causing a predetermined one of the first speakers to emit sound, where processing the input information may include comparing an angle of deviation between an actual position of the predetermined one of the speakers and the position information. As mentioned before, the relevant parameters of the predetermined one of the loudspeakers are known to the tester terminal, i.e. the actual position of the predetermined one of the loudspeakers is known to the tester terminal.
The deviation angle is an angle between two positions corresponding to the actual position of the speaker and the position information with respect to the subject (origin) in a spatial coordinate system established with the subject as the origin. The value of the deviation angle may be equal to or greater than 0 degrees. Specifically, a spatial coordinate system may be established with the midpoint of the subject's binaural line as the origin and the midsagittal plane, coronal plane, and transverse plane of the subject as orthogonal planes. In this case, the deviation angle can be calculated easily.
It will be readily appreciated that the smaller the deviation angle, the more accurate the subject can be considered to be in identifying the location of the sound emitted by the sound emitting device. Conversely, the larger the deviation angle, the more inaccurate the subject can be said to recognize the position of the sound emitted by the sound emitting device. Therefore, the deviation angle can intuitively reflect the sound source localization capability of the subject.
Illustratively, in another example, the first speaker of the sound delivery device includes two speakers, the method includes causing a predetermined one of the first speakers to emit sound, where processing the input information may include determining whether the position information input by the subject is equal to an actual position of the predetermined one of the speakers. In other words, it is determined whether the speaker of the subject selected in the input information is the predetermined one that actually uttered.
Specifically, the two speakers of the first speaker may be located on the left and right sides of the subject, respectively, and the position information input by the subject may include the left or right side. Therefore, the term "equal to" here means that the position information input by the subject and the actual position of the predetermined one of the speakers are both the left side of the subject or the position information input by the subject and the actual position of the predetermined one of the speakers are both the right side of the subject.
The left and right sides of the subject are also based on the spatial coordinate system established above with the subject as the origin. For example, bounded by the midsagittal plane of the subject, the two sides are the left and right sides of the subject, respectively. Therefore, the judgment result and the correctness of the test subject can be obtained in each test, and the proportion of the correct result in the judgment results can be obtained after a plurality of tests. In this example, the relative positions of the two speakers are changed when the correct result reaches a certain percentage (e.g., 75%), and then the next set of tests is performed. After a plurality of such tests are performed, until the proportion of correct results in the judgment results of the subject fails to reach the proportion, the relative positions (e.g., relative angles in the coordinate system described above) of the two speakers at which the proportion of the correct results can reach the proportion at the last time, that is, the minimum angle which can be correctly discriminated by the subject is taken as the minimum angle discrimination threshold of the subject, so that the minimum angle discrimination threshold in the sound source localization capability of the subject can be finally determined.
As an example, the actual positions of at least two speakers of the first speaker of the sound giving device have been stored in the local memory of the tester terminal or the server in advance, and at this time, the actual position of a predetermined one of the speakers may be acquired from the local memory or the server. This approach is responsive and can take full advantage of the processing speed and high memory capacity of the local memory or server.
As another example, the tester terminal may detect the actual position of a predetermined one of the speakers in real time by an infrared sensor or the like, and at this time, the detected actual position of the predetermined one of the speakers may be acquired by the infrared sensor or the like. The method has accurate detection, can obtain a result more consistent with the actual situation, and avoids errors caused by tiny movement of the loudspeaker.
Illustratively, processing the input information may further include calculating a reaction time of the subject. The reaction time is defined as the difference between the time of receipt of the input information and the actual sound production time of a predetermined one of the speakers. The reception time of the input information is a time at which the subject terminal receives the input information of the subject, which is reflected as a time instant. In addition, as mentioned above, the relevant parameters of the predetermined one of the speakers are known to the tester terminal, i.e. the tester terminal knows the actual sound emission time of the predetermined one of the speakers. The actual sound emission time of a predetermined one of the speakers is reflected as another time. These two moments have the same format for the calculation of the reaction time by the tester terminal.
It will be readily appreciated that the smaller the reaction time, the more rapidly the subject can be considered to identify the location of the sound emitted by the sound delivery device. Conversely, the longer the reaction time, the slower the subject can be considered to recognize the position of the sound emitted from the sound emitting device. Thus, the reaction time may also intuitively reflect the sound source localization capabilities of the subject.
Furthermore, any deviation angle that falls within a small neighborhood of 0 degrees (referred to herein as the right neighborhood) is reasonable for subjects with a general level of sound source localization capability. In other words, when the deviation angle obtained by the comparison falls within the small neighborhood (e.g., 5 degrees), the current judgment result of the subject can be considered as valid, and can reflect the true hearing level of the subject. Accordingly, when the compared deviation angle falls outside the small neighborhood, the present judgment result of the subject may be considered as invalid and may not reflect the true hearing level of the subject. It will be appreciated that the 5 degrees described above are used as examples only, and the interval length of the small neighborhood may be determined according to the age stage or physical signs of the subject, etc.
Further, since there may be a correlation between the reaction time and the correctness of the determination result, in another embodiment, the reaction time obtained from one input information may be weighted to calculate the nominal deviation angle based on the deviation angle. Wherein the proportional weight of the reaction time should be less than the proportional weight of the deviation angle. Then, the judgment result of the subject is screened according to whether the nominal deviation angle is within a small neighborhood of 0 degree (for example, 5 degrees) to avoid the interference of invalid data. Therefore, the test error can be reduced, and the accuracy of the test result is improved.
Similarly to the first speaker, the tester terminal may also send a sound emission instruction to the sound emission device to cause the second speaker of the sound emission device to emit sound. Also, the tester terminal may receive and process input information from the subject terminal after the second speaker sounds.
And S4, generating report information according to the processing result.
The tester terminal processes the input information to derive parameters including, but not limited to, deviation angle and reaction time, or minimum angle discrimination threshold and reaction time. Thus, the generated report information may also include parameters such as deviation angle or minimum angle discrimination threshold, and reaction time. In addition, the degree of compliance of the subject may be quantified and transmitted to the tester terminal as one of the influencing factors of the report information. The report information can be presented on a screen through a display or played through voice playing. This may facilitate the knowledge of the reporting information.
Therefore, in the embodiment of the invention, the test result can be obtained by controlling the sound giving device to sound and receiving and processing the input information by the tester. The process simplifies the testing process, reduces the burden of the work of recording, observing and the like of a tester, and improves the testing efficiency and the accuracy of the testing result.
Illustratively, prior to S1, the method further includes signaling a start of the test to the subject terminal.
This may be done based on the way the communication connection between the tester terminal and the subject terminal is made. For example, a signal to start the test may be sent to the subject terminal over a wireless communication connection such as bluetooth, wireless fidelity (Wi-Fi). This may indicate to the subject that the test is about to begin, to encourage concentration, and thus obtain test results closer to the true level of the subject. Of course, the test start signal may also be sent to the subject terminal via a wired communication connection.
Illustratively, after S3, the method further comprises: the actual number of utterances of the sound-imparting means is compared with a predetermined number. Wherein the predetermined number of times may be equal to or greater than the number of at least two speakers in the sound delivery device.
After the comparison, when the number of actual utterances is less than the predetermined number, the steps S1-S3 are repeated. In fact, performing steps S1-S3 may complete one test, that is, repeating steps S1-S3 may complete multiple tests. In this way, contingencies in testing can be eliminated to reduce random errors, thereby significantly improving the accuracy of the test results. And before the whole set of test is not finished, report information does not need to be generated after the single test is finished, so that the test flow is simplified. This can shorten the processing time of the tester terminal and improve the test efficiency.
Specifically, in each test, the speaker that emits sound may be randomly selected as any of the plurality of speakers. In other words, each speaker may sound multiple times during the entire set of tests, and the speaker that sounds each time may be different from or the same as the speaker that last occurred.
Further, in case the sound delivery device comprises more than two speakers, the position of the speakers that sound is not changed with respect to the subject, i.e. the position of the speakers that sound is fixed with respect to the subject, but the order of the individual speakers sound is random. At this point, the number of times each speaker sounds may be the same throughout the entire set of tests. For example, the sound giving means may comprise 7 loudspeakers, each of which may each sound 7 times. That is, the entire set of tests in this case includes 49 single tests. Therefore, the sound source positioning capability of the test subject can be tested in terms of the sound source position identification deviation, and the accuracy of the test result is improved as much as possible through multiple tests.
Further, in the case where the sound-imparting device includes two speakers, the position of the speaker that emits sound may be changed, and the position of the speaker that emits sound last is closer to the midsagittal plane of the subject than the position of the speaker that emits sound initially. At this time, the order and number of times each speaker sounds in the entire set of tests may be determined by an adaptive method. The basic principle is that when the judgment result of the subject is correct and the accuracy of the multiple tests reaches a certain proportion, the position of the speaker which sounds next time is closer to the median sagittal plane of the subject than the position of the speaker which sounds last time; when the judgment result of the subject is 'wrong' and the error rate of the multiple tests reaches a certain proportion, the position of the loudspeaker which sounds next time is farther from the median sagittal plane of the subject than the position of the loudspeaker which sounds last time. When the number of times reaches a predetermined number, the position of the speaker which generates the next sound is closer to the midsagittal plane of the subject than the position of the speaker which generates the previous sound, regardless of whether the determination result is "correct" or "incorrect". For example, in a part of the set of tests, the angle between the line connecting the position of the speaker generating each sound and the subject and the median sagittal plane of the subject is, in turn, for example, 90-75-60-45-60-45-60-55-50-55-50-55-50-55 degrees, or for example, 45-30-15-10-5-2.5-5-2.5-5 degrees. Compared with the existing testing method, the embodiment of the invention can test the sound source positioning capability of the testee in terms of the sound source position discrimination threshold, and reduce the redundant testing times as much as possible so as to improve the testing efficiency.
Then, until the comparison results in that the number of actual utterances is equal to the predetermined number, step S4 is executed. At this time, the tester terminal has performed a sufficient number of tests, and therefore can obtain a test result with sufficiently high accuracy, and generate report information from the test result. The report information can be displayed or played to make the tester know.
Illustratively, the tester terminal may be communicatively coupled to the stimulation device and configured to control activation of the stimulation device. Preferably, the tester terminal is in wireless communication with the stimulation device to eliminate distance limitations therebetween. For example, the connection is made wirelessly via communication means such as bluetooth, wireless fidelity (Wi-Fi), and the like. In this way, the stimulation device can be activated without close-up operation to eliminate the disturbance of the test person to the subject during the test.
Illustratively, in one example, after S3, the method further comprises: and comparing the deviation angle with a preset reference value, and sending an actuating instruction to the actuating device to actuate the actuating device when the deviation angle is smaller than the preset reference value.
The motivational devices are intended to improve the fit of the subject and may include motorized toys, playing devices, and the like. When the deviation angle is smaller than a preset reference value, the exciting device is started, so that the attention of the testee is attracted by the interestingness of the exciting device, and the test of the sound source positioning capability is smoothly carried out; or the fatigue of the subject is reduced by the leisure of the exciting device, and the mental stress is relieved, so that the test of the sound source positioning capability is carried out efficiently. Of course, the energizing means is not limited to the above examples.
The predetermined reference value may be set to any value in a small neighborhood of 0 degrees (for example, 5 degrees) of the aforementioned deviation angle, which may facilitate comparison by the tester terminal. The predetermined reference value may have different relative sizes for different subjects. For example, for a group of subjects such as children with less mental maturity, the predetermined reference value may be set to a larger value in the small neighborhood. For a population of subjects, such as adults with more sophisticated mental skills, the predetermined reference value may be set to the smaller value in the small neighborhood. Alternatively, the predetermined reference value may also be set based on the hearing condition of the subject himself, for example, whether or not a cochlear implant, a hearing aid, or the like is worn. Therefore, the method of the invention can combine high matching degree and high testing efficiency through the balance of the concentration degree and the relaxation degree for different subjects.
However, independently of the above-described condition for sending the start instruction, the tester terminal can control the activation of the stimulation device. For example, the tester terminal may control the activation of the stimulation device depending on the age stage of the subject. In a preferred embodiment, the tester terminal may be turned on when the subject is a child, thereby improving the fitting degree of the subject, and not turned on when the subject is an adult, thereby saving a part of the test procedure to improve the test efficiency as a whole. For example, the tester terminal may control the activation of the stimulation device depending on the hearing ability of the subject. In a preferred embodiment, the tester terminal can be opened when the test subject is a hearing-impaired person, so as to reduce the mental stress of the test subject and avoid the error between the test result and the actual situation from being too large. Of course, the control of the activation of the stimulation device by the tester terminal is not limited to the above-described embodiment.
Exemplarily, in another example, after S3, the method further includes: when the position information input by the subject is judged to be equal to the actual position of the predetermined one of the speakers, an activation instruction is sent to the excitation device to cause the excitation device to activate. The function of the stimulation device and the control of the tester terminal to turn on the stimulation device are the same as described above.
In addition, the embodiment of the present invention further provides a tester terminal, which includes a memory, a processor and a computer program stored in the memory and running on the processor, wherein the processor executes the computer program to implement the steps of the method executed by the tester terminal in fig. 1.
In addition, the embodiment of the present invention also provides a subject terminal, which includes a memory, a processor and a computer program stored in the memory and running on the processor, wherein the processor executes the program to implement the steps of the method executed by the tester terminal in fig. 1.
In addition, the embodiment of the invention also provides a computer storage medium, and the computer storage medium stores a computer program. The computer program, when executed by a processor, may implement the steps of the method of fig. 1, previously described, as performed by the tester terminal. For example, the computer storage medium is a computer-readable storage medium.
Thus, according to the embodiment of the invention, the relevant input information from the terminal of the subject can be obtained by controlling the sound-giving device to give out sound, so that the input information is processed to generate the test result. The attention and the degree of cooperation of the testee can be improved by controlling the exciting device. Therefore, the method of the invention can simplify the testing process, improve the automation degree, reduce the burden of testers and obtain a comprehensive testing result. Meanwhile, the problem that the testee is not matched with the test is also solved, so that the test accuracy and the test efficiency are improved.
