It will be apparent that the invention is not limited to the specific details set forth in the skilled artisan. Preferred embodiments of the present invention are described in detail below, however, the present invention may have other embodiments in addition to these detailed descriptions.

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 the embodiments set forth herein. It should be appreciated 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 a description thereof 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 giving device. Preferably, the sound giving means may comprise a first speaker and a second speaker. The first speakers are all arranged on the same horizontal plane, and the second speakers are arranged outside the horizontal plane where the first speakers are arranged. 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 speakers are arranged at different positions on the same horizontal plane. In this way, test conditions for distinguishing different spatial positions of the sound source by the subject can be provided, so that the sound source positioning capability can be tested.
FIG. 1 is a schematic flow chart of a method for testing sound source positioning capability according to an embodiment of the present invention. A tester terminal, a subject terminal, and a sound-giving device are shown in fig. 1. The method may include:
s1, sending a sounding instruction to the sound giving device so that the sound giving device can give out sound.
Illustratively, prior to S1, it may include: the communication connection between the tester terminal and the sound giving device is realized. Preferably, the tester terminal is connected to the audio-giving device in a wired communication manner, so as to reduce audio quality loss. For example, the tester terminal is connected to the sound-giving device via an audio cable.
As one example, the tester terminal establishes communication with each of the at least two speakers of the acoustic device through a serial port. Each loudspeaker corresponds to a relay, and a plurality of relays form a control circuit. The common end of each relay is communicated with the serial port of the terminal of the tester, and the normally open contact of each relay is respectively communicated with each loudspeaker. When the tester terminal sends a sounding instruction to the sounding device, the corresponding relay responds to the sounding instruction to enable the normally open contact to be closed, so that the serial port of the tester terminal is communicated with the corresponding loudspeaker, and the corresponding loudspeaker can make a sound according to the expectations. It will be appreciated that the intensity, frequency, duration, etc. of the sound may be controlled by audible instructions. Generally, in an embodiment of the present invention, the sound emitted from the speaker lasts for a period of about 2s to 3s. Preferably, the sound emitted by the loudspeaker can simulate natural sounds such as thunder, bird song, water flow sound and the like, or the sound emitted by the loudspeaker can be pure sound, which can be selected according to the actual hearing condition of the subject.
Illustratively, sending the sound emission instructions to the sound emitting device includes sending the sound emission instructions to a predetermined one of the first speakers. For example, a plurality of speakers are arranged around the subject, and the tester terminal may send a sound instruction to one of the plurality of speakers. Where "predetermined" means that which speaker will sound is actually determined by the tester terminal. In other words, although the speaker that utters can be randomly selected as any speaker of the plurality of speakers, it is known to the tester terminal which speaker will objectively utter. Accordingly, the relevant parameters of the predetermined one speaker are also known to the tester terminal.
S2, receiving input information from a subject terminal, wherein the input information comprises position information of sound input by the subject.
Illustratively, prior to S2, it may include: and realizing communication connection between the tester terminal and the subject terminal. Preferably, the tester terminal is in wireless communication with the subject terminal to eliminate distance limitations therebetween. For example, wireless connection is through bluetooth, wireless fidelity (Wi-Fi), or the like. Because the distance limitation 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 in the testing process. Of course, the tester terminal and the subject terminal can also be connected in a wired communication manner, so that the quality of signal transmission is higher and more stable.
Illustratively, the subject terminal may receive input information through an input interface, such as through a physical button, a virtual button in a touchable screen, or the like. This way the operation is convenient. Or the subject terminal may receive the input information through a non-contact manner such as voice input. The applicable crowd scope of this kind of mode is wider. The input information includes positional information of a sound input by the subject. In particular, this refers to the relative position in spatial orientation of the sound emitted by the speaker that the subject subjectively perceives, and not to the actual relative position of the sound in spatial orientation. Thus, the same sound emitted by the acoustic device may correspond to different input information for different subjects.
S3, processing the input information.
Illustratively, in one example, the first speaker of the acoustic device comprises more than two speakers, and the method comprises causing a predetermined one of the first speakers to emit sound, at which time processing the input information may comprise comparing an angle of deviation between an actual position of the predetermined one of the speakers and the position information. As previously mentioned, 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 refers to an angle formed between two positions corresponding to the actual position and position information of the speaker 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 can be established by taking the midpoint of the binaural connecting line of the subject as an origin and taking the median sagittal plane, the coronal plane and the cross section 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 angle of deviation, the more accurate the subject can be considered to recognize the position of the sound made by the sound-giving device. Conversely, the greater the angle of deviation, the more inaccurate the subject can be considered to be in recognizing the location of the sound made by the acoustic device. Thus, the deviation angle can intuitively reflect the sound source localization capability of the subject.
In another example, the first speaker of the acoustic device comprises two speakers, and the method comprises causing a predetermined one of the first speakers to emit sound, at which time processing the input information may comprise determining whether the subject-input location information is equal to an actual location of the predetermined one speaker. In other words, it is determined whether or not the speaker selected in the input information of the subject is the predetermined one of the speakers that actually uttered.
In particular, the two speakers of the first speaker may be located on the left and right sides of the subject, respectively, and the positional information input by the subject may include the left or right side. Thus, "equal to" herein means that both the subject-input positional information and the actual position of the predetermined one speaker are to the left of the subject or both the subject-input positional information and the actual position of the predetermined one speaker are to the right 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, the subject is bounded by the median sagittal plane, which is flanked by left and right sides of the subject, respectively. In this way, in each test, the judging result and the correctness of the judging result of the test subject can be obtained, and after multiple tests, the proportion of the correct result in the multiple judging results can be obtained. In this example, the relative positions of the two speakers are changed when the correct result reaches a certain ratio (e.g., 75%) and then the next set of tests is performed. After a plurality of such tests are performed until the ratio of correct results among the judgment results of the subject cannot reach the ratio, the relative positions of the two speakers (for example, the relative angles in the coordinate system described above) at which the ratio of the last correct result can reach the ratio, that is, the minimum angle at which the subject can correctly discriminate is taken as the minimum angle discriminating threshold of the subject, so that the minimum angle discriminating threshold in the sound source positioning ability of the subject can be finally determined.
As an example, the actual positions of at least two loudspeakers of the first loudspeaker of the sound-giving device have been stored in advance in a local memory or server of the tester terminal, from which local memory or server the actual position of a predetermined one of the loudspeakers can be retrieved. This way of responding quickly, the processing speed and high storage capacity of the local memory or server can be fully utilized.
As another example, the tester terminal detects 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 detection in this way is accurate, and results which are more consistent with the actual situation can be obtained, so that errors caused by small movements of the loudspeaker are avoided.
Illustratively, processing the input information may further include calculating a response 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 emission time of a predetermined one of the speakers. The reception time of the input information is a time when the subject terminal receives the input information of the subject, and is reflected as one time. In addition, as previously mentioned, the relevant parameters of the predetermined one speaker are known to the tester terminal, i.e. the tester terminal knows the actual sound emission time of the predetermined one speaker. The actual sound emission time of a predetermined one of the speakers is reflected as another time. The two moments have the same format for the tester terminal to calculate the reaction time.
It will be readily appreciated that the smaller the reaction time, the more quickly the subject can be considered to recognize the location of the sound made by the acoustic device. Conversely, the greater the response time, the more slowly the subject can be considered to recognize the location of the sound made by the acoustic device. Thus, the reaction time can also intuitively reflect the subject's sound source localization ability.
Furthermore, any deviation angle that falls into 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 (for example, 5 degrees), the determination result of the subject can be considered valid, and the true hearing level of the subject can be reflected. Accordingly, when the deviation angle obtained by comparison falls outside the small neighborhood, the determination result of the subject can be considered as invalid, and the true hearing level of the subject cannot be reflected. It will be appreciated that the 5 degrees described above are for example only, and that the interval length of the small neighborhood may be determined based on the age or physical sign of the subject, etc.
Further, since there may be a correlation between the reaction time and the positive or negative of the determination result, in another embodiment, the reaction time obtained from one input information may be weighted, and the nominal deviation angle may be calculated based on the deviation angle. Wherein the proportional weight of the reaction time should be smaller than the proportional weight of the deviation angle. And then screening the judging result of the subject according to whether the nominal deviation angle falls within a small neighborhood (for example, 5 degrees) of 0 degrees so as to avoid the interference of invalid data. Therefore, the test error can be reduced, and the accuracy of the test result is improved.
Similar to the first speaker, the tester terminal may also send a sound emission instruction to the sound emitting device to cause the second speaker of the sound emitting device to emit sound. And, the tester terminal may also receive and process the input information from the subject terminal after the second speaker sounds.
S4, generating report information according to the processing result.
The tester terminal processes the input information to obtain parameters including, but not limited to, bias angle and reaction time, or minimum angle discrimination threshold and reaction time. Thus, the generated report information may also include parameters such as the deviation angle or minimum angle discrimination threshold, and the reaction time. In addition, the matching degree of the subject may be quantified and then transmitted to the tester terminal as one of the influencing factors of the report information. The report information may be presented on a screen via a display or played by way of voice playback. This may facilitate the learning of reporting information.
It can be seen that in the embodiment of the invention, the test result can be obtained by controlling the sound producing device by the tester and receiving and processing the input information. The process simplifies the test flow, lightens the workload of the tester for recording, observing and the like, and improves the test efficiency and the accuracy of the test result.
Illustratively, prior to S1, the method further comprises signaling the subject terminal to start the test.
This may be done based on the manner of communication connection between the tester terminal and the subject terminal. For example, a signal to the subject terminal to start a test may be sent over a wireless communication connection such as bluetooth, wireless fidelity (Wi-Fi). This may prompt the subject that the test is about to begin to focus on it, thereby obtaining test results that are 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 acoustic device 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 loudspeakers in the sound-giving device.
After the comparison, when the actual number of utterances is less than the predetermined number of times, the steps S1-S3 are repeated. In practice, performing steps S1-S3 may complete one test, that is, repeating steps S1-S3 may complete multiple tests. In this way, contingencies in the test 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 uttered the sound may be randomly selected as any speaker of the plurality of speakers. In other words, each speaker may sound multiple times during the whole set of tests, and the speaker for each sound may be different or the same as the speaker that last occurred.
Further, in case the sound emitting device comprises more than two loudspeakers, the position of the sound emitting loudspeakers with respect to the subject does not change, i.e. the position of the sound emitting loudspeakers with respect to the subject is fixed, but the order in which the individual loudspeakers sound are emitted is random. At this time, the number of sounds made by each speaker may be the same throughout the entire set of tests. For example, the sound-giving device may comprise 7 loudspeakers, each of which may sound 7 times individually. That is, the whole set of tests in this case includes 49 single tests. This makes it possible to test the sound source positioning ability of the subject in terms of the sound source position recognition deviation and to improve the accuracy of the test result as much as possible by a plurality of tests.
Furthermore, where the sound emitting device comprises two speakers, the position of the speaker that emits sound may vary, and the position of the speaker that emits sound last is closer to the mid-sagittal plane of the subject than the position of the speaker that emits sound initially. At this time, in the whole set of test, the order and the number of sounds of the respective speakers can be determined by an adaptive method. The basic principle is that when the judging result of the subject is 'correct' and the accuracy of multiple tests reaches a certain proportion, the position of the loudspeaker making the next sound is closer to the median sagittal plane of the subject than the position of the loudspeaker making the last sound; 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 sounding next time is farther from the median sagittal plane of the subject than the position of the loudspeaker sounding last time. When the number of times is reached, the speaker for the next sound production is positioned closer to the median sagittal plane of the subject than the speaker for the last sound production, regardless of whether the determination result is "correct" or "incorrect". For example, in a portion of the overall test, the angle between the line of the speaker and the subject's location for each utterance and the subject's median sagittal plane is, in turn, for example, 90-75-60-45-60-45-60-55-50-55-50-55-50-55 degrees, or 45-30-15-10-5-2.5-5-2.5-5-2.5-5 degrees. Compared with the existing testing method, the method can test the sound source positioning capability of the subject in terms of the sound source position distinguishing threshold, and reduce redundant testing times as much as possible so as to improve testing efficiency.
Then, until the actual number of sounds obtained by the comparison is equal to the predetermined number of sounds, step S4 is performed. At this time, the tester terminal has performed a test a sufficient number of times, and thus can obtain a test result with a sufficiently high accuracy, and generate report information according to 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 the tester terminal is configured to be able to control the activation of the stimulation device. Preferably, the tester terminal is in wireless communication with the excitation device to eliminate distance limitations therebetween. For example, wireless connection is through bluetooth, wireless fidelity (Wi-Fi), or the like. In this way, the stimulation device can be activated without close range operation to eliminate the interference of the tester on the subject during the test.
Illustratively, in one example, after S3, the method further comprises: comparing the deviation angle with a preset reference value, and sending a starting instruction to the excitation device when the deviation angle is smaller than the preset reference value so as to enable the excitation device to start.
The motivating means is intended to increase the degree of fit of the subject, which may include an electric toy, a playing device, etc. When the deviation angle is smaller than a preset reference value, the excitation device is started, so that the interest of the excitation device attracts the attention of a subject, and the sound source positioning capability test is smoothly carried out; or the fatigue of the subject is reduced by the leisure nature of the excitation device, and the mental stress is relieved, so that the sound source positioning capability can be effectively tested. Of course, the excitation means is not limited to the above example.
The predetermined reference value may be set to any value in a small neighborhood (e.g., 5 degrees) of 0 degrees of the aforementioned deviation angle, which may facilitate the comparison by the tester terminal. The predetermined reference values may have different relative sizes for different subjects. For example, for a population of subjects such as children whose mind is less mature, the predetermined reference value may be set to a larger value in the small neighborhood. For a population of subjects such as mentally mature adults, the predetermined reference value may be set to a smaller value in the small neighborhood. Or the predetermined reference value may be set based on the hearing condition of the subject itself, for example, whether to wear a cochlear implant, a hearing aid, or the like. Therefore, for different subjects, the method of the invention can have high matching degree and high test efficiency through the balance of the concentration degree and the relaxation degree.
However, independently of the above-described condition for sending the start instruction, the tester terminal can control the activation of the stimulus means. 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 fit of the subject, and turned off when the subject is an adult, thereby saving a portion 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 turned on when the subject is a hearing impaired person, so as to reduce the mental stress of the subject, and avoid excessive error between the test result and the actual situation. Of course, the control of the activation of the stimulation device by the tester terminal is not limited to the above-described embodiment.
Illustratively, in another example, after S3, the method further comprises: and when the position information input by the subject is judged to be equal to the actual position of the preset loudspeaker, sending an actuating instruction to the actuating device so as to actuate the actuating device. Wherein the function of the excitation device and the control of the opening of the excitation device by the tester terminal are the same as described above.
In addition, the embodiment of the invention also provides a tester terminal, which comprises a memory, a processor and a computer program stored in the memory and running on the processor, wherein the processor realizes the steps of the method executed by the tester terminal in the figure 1 when executing the program.
In addition, the embodiment of the invention also provides a subject terminal, which comprises a memory, a processor and a computer program stored on the memory and running on the processor, wherein the processor realizes the steps of the method executed by the tester terminal in the figure 1 when executing the program.
In addition, the embodiment of the invention also provides a computer storage medium, on which the computer program is stored. The steps of the method performed by the tester terminal in fig. 1 described above may be implemented when the computer program is executed by a processor. The computer storage medium is, for example, 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 producing device to produce sound, so that the input information is processed to generate a test result. The attention of the subject can also be improved and the degree of fit can also be improved by controlling the excitation device. Therefore, the method of the invention can simplify the test flow, improve the automation degree, lighten the burden of a tester and obtain the comprehensive test result. Meanwhile, the difficulty that the test is not matched with the test by the test subject is overcome, so that the accuracy and the efficiency of the test are improved.
