In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present application with unnecessary detail.

In order to explain the technical solution described in the present application, the following description will be given by way of specific examples.

The terminal device 11 is configured to generate a control command and transmit the control command to the headset 12.

And the control instruction is used for generating a test audio signal by the earphone.

It should be noted that the terminal device 11 may be, but is not limited to, a mobile phone or a computer, and the headset 12 may be, but is not limited to, a wired headset or a wireless headset, and accordingly, the transmission mode between the terminal device 11 and the headset 12 includes, but is not limited to, a wired mode or a wireless mode.

In the embodiment of the application, the audiometry system can realize accurate audiometry on the hearing of a tested person.

Example two

As can be seen from the first embodiment, the audiometric system includes a terminal device and an earphone communicatively connected to the terminal device, and the purpose of this implementation is to introduce a process of taking the earphone of the audiometric system as an execution main body to perform audiometry on the hearing of a person to be tested.

It should be noted that the parser includes, but is not limited to, a java parser or a python parser.

Step S203, generating a test audio signal according to the sound parameter.

The test audio signal refers to a carrier with frequency and amplitude label information of regular sound waves of voice, music and sound effects.

Specifically, the process of generating the test audio signal according to the sound parameters may be: firstly, respectively constructing an excitation model, a sound channel model and a radiation model of a test audio signal; then, generating an excitation signal by exciting the digital model; then, the sound parameters of the input sound channel model are processed digitally; and finally, radiating the sound parameters subjected to digital processing by a radiation model to obtain a test audio signal.

It can be understood that the earphone of the embodiment of the application generates the test audio signal according to the sound parameter obtained by analyzing the control instruction, and the test audio signal does not need to be generated through the terminal device, thereby avoiding the situations of inaccurate sound pressure level, distortion and the like in the process of transmitting the test audio signal from the terminal device to the earphone due to technical obstacles, and being capable of accurately measuring the hearing of a person to be tested.

Step S204, playing the test audio signal.

EXAMPLE III

In the second embodiment, although it is possible to avoid the situation that the sound pressure level is inaccurate and distortion occurs in the process of transmitting the test audio signal from the terminal device to the earphone due to technical obstacles, the state of the test audio signal in step S202 of the second embodiment is a digital state, the state of the test audio signal in step S203 of the second embodiment is an analog state, and in the process of converting the test audio signal from the digital state to the analog state, the sound pressure level of the test audio signal played to the testee cannot be accurately predicted due to noise interference or the influence of device parameters, and distortion may occur, so that the hearing of the testee cannot be accurately measured.

The purpose of this embodiment is to avoid the inaccurate sound pressure level and the distortion of the test audio signal that is played to the testee, which results in the inaccurate audiometry of the testee.

Referring to fig. 3, another schematic flow chart of an audiometric method provided in the second embodiment of the present application is shown, where the method may be specifically applied to headphones, including but not limited to wired headphones or wireless headphones, and the method may include the following steps:

and S301, acquiring a control instruction of the terminal equipment.

And step S302, analyzing the control command to obtain the sound parameter.

Where the state of the test audio signal comprises a digital state or an analog state, the calibration data includes, but is not limited to, an audio parameter, a wavelength parameter, an amplitude parameter, a phase parameter, or the like.

The state of the test audio signal generated in step S303 based on the sound parameter is a digital state, and the state of the test audio signal played in step S307 is an analog state.

Specifically, a correspondence between the test audio signal in the digital state and the calibration data is established in advance, and the calibration data is searched based on the test audio signal in the digital state.

For example, in a mute environment such as an acoustic anechoic room or a mute room, the earphone first executes the steps S301 to S303 to obtain a test audio signal in a digital state, converts the state of the test audio signal from the digital state to an analog state, and plays the test audio signal in the analog state to an acoustic parameter analysis device such as an acoustic analyzer; then, the earphone acquires and records calibration data measured by the acoustic parameter analysis device according to the test audio signal in the simulation state; and finally, the headset establishes a corresponding relation between the calibration data and the test audio signal in the digital state.

Step S305, performing digital-to-analog conversion on the test audio signal in the digital state to obtain a test audio signal in an analog state.

Specifically, the digital-to-analog converter may perform digital-to-analog conversion on the test audio signal in the digital state to obtain a test audio signal in an analog state.

And S306, calibrating the test audio signal in the simulation state based on the calibration data.

It can be understood that parameters such as audio parameters, wavelength parameters, amplitude parameters, phase parameters and the like of the test audio signal in the analog state are respectively calibrated based on the calibration data, so that the inaccurate sound pressure level and distortion of the audio detection signal played to the tested person due to noise interference or device parameter influence are avoided, and the effect of accurately measuring the hearing of the tested person is further achieved.

It should be noted that, in the process of calibrating the test audio signal in the analog state based on the calibration data, the hardware architecture of the headphone system and the acoustic structure of the headphone system are also depended on.

And step S307, playing the test audio signal.

It should be noted that step S307 is the same as step S204, and is not described herein again.

In the embodiment of the application, the earphone acquires calibration data according to the test audio signal in the digital state, and calibrates the test audio signal in the analog state based on the calibration data, so that the inaccuracy and distortion of the sound pressure level of the audio detection signal played to the tested person due to noise interference or device parameter influence are avoided, and the effect of accurately testing the audiometry of the tested person is further achieved.

Example four

As can be seen from the first embodiment, the audiometric system includes the terminal device and the earphone communicatively connected to the terminal device, and the second embodiment is to introduce a process of taking the earphone of the audiometric system as an execution main body to perform audiometry on the hearing of a person to be tested.

In this embodiment, a process of taking the terminal device of the audiometric system as an execution subject to audiometry of the hearing of the subject is described.

Referring to fig. 4, a schematic flow chart of a listening method provided in the fourth embodiment of the present application is shown, where the method may be specifically applied to a terminal device, where the terminal device may be, but is not limited to, a mobile phone or a computer, and the method may include the following steps:

and step S401, generating a control command.

Specifically, the terminal device generates a control instruction according to a pre-selected sound parameter.

The sound parameter sound includes, but is not limited to, a sound type parameter, a sound frequency parameter, or a sound intensity parameter, and the sound type parameter includes, but is not limited to, a pure sound parameter, an sing sound parameter, or an impulse sound parameter.

Thus, a sound parameter is formed according to the selected sound type parameter, the sound audio parameter and the sound intensity parameter, and then a control instruction is generated according to the sound parameter to test the hearing of the tested person.

It should be noted that, if a detection result is obtained subsequently, for example, a confirmation operation of the detected side is detected, the sound intensity parameter selected in the third step is used as a sound intensity threshold parameter, that is, the sound intensity parameter in the sound parameters corresponding to the confirmation operation is used as a sound intensity threshold parameter, then the second step is returned to re-select a sound frequency parameter, and the subsequent selection step is continuously performed.

Wherein the sound parameters include, but are not limited to, a sound type parameter, a sound frequency parameter, or a sound intensity parameter.

And step S402, transmitting the control instruction to the earphone.

The confirmation operation includes, but is not limited to, a click operation, a sliding operation, and the like performed by the subject in a preset area of the display interface of the terminal device.

Specifically, when the confirmation operation of the subject is detected, indicating that the subject has heard the played test audio signal, and the test audio signal is generated from the sound parameter, the confirmation operation is associated with the sound parameter, and the sound parameter is recorded as the hearing parameter of the subject.

Further, in step S401, the sound intensity parameter of the sound parameters corresponding to the detected result, for example, when the confirmation operation of the subject is detected, is used as the sound intensity threshold parameter, so that the sound intensity parameter of the hearing parameters is the sound intensity threshold parameter.

Step S404, generating a hearing curve graph according to the hearing parameters.

It should be noted that the sound type parameter is selected according to the hearing conditions of different testees, for example, a pure tone parameter is selected for a general testee, and sing tone parameters or a pulse tone parameter is selected for a tinnitus testee.

It can be understood that, under the premise of determining the sound type parameter, the hearing curve graph of the tested person is generated according to the sound audio parameter and the sound intensity parameter.

Therefore, the embodiment can further analyze the partial frequency band of the hearing loss of the tested person according to the obtained hearing curve.

In the embodiment of the application, the examinee can be accurately audited to obtain the hearing curve graph.

Referring to fig. 5, a schematic flowchart of an audiometric method according to an embodiment of the present application after step S204 in fig. 2 is shown. The method may be particularly applicable to headphones, which may be, but is not limited to, wired headphones or wireless headphones, and may comprise the steps of:

It will be appreciated that a first speech test may be subsequently performed on the subject based on the hearing parameters.

And S503, acquiring the first speech test text content from the database.

The first speech test text content refers to content for performing a further first speech test on the hearing of the tested person, such as "milk", "stool", and the like.

It should be noted that the database may be a database built in the headset.

Step S504, generating a first speech test audio signal according to the first speech test text content and the hearing parameter.

It can be understood that the present embodiment generates the first text test audio signal based on the hearing parameters and the first speech test text content to further test the hearing of the subject.

And step S505, transmitting the first speech test text content to the terminal equipment.

It can be understood that, because the testee receives the first speech test audio signal that the earphone broadcast after, the testee can follow the reading according to the text audiometry signal of the broadcast of listening, through transmitting first speech test text content to terminal equipment for terminal equipment can be according to the text content of the first speech test text content detection testee that receives follow the reading the speech signal who sends unanimously, reaches the effect of carrying out first speech test to the testee.

Step S506, playing the first speech test audio signal.

Step S602, the first speech test instruction is transmitted to the earphone.

Step S603, obtaining the voice signal of the tested person and the first speech test text content output by the earphone.

The voice signal is a signal sent by a first speech test audio signal played by the earphone of the testee.

It can be understood that, because the first speech test audio signal played by the earphone is generated by the first speech test text content and the hearing parameter, the tested person is further subjected to the first speech test by obtaining the voice signal of the tested person and comparing the first speech test text content output by the earphone.

Step S604, if the text content of the voice signal of the tested person is identified to be inconsistent with the text content of the first speech test, taking the part of the text content of the first speech test inconsistent with the text content of the voice signal as missing text content and recording.

It can be understood that, if the text content of the voice signal of the tested person is identified to be inconsistent with the first speech test text content, the part of the text content of the voice signal inconsistent with the first speech test text content is the text content of the tested person who follows the reading error, and the part of the text content of the first speech test text content inconsistent with the text content of the voice signal is taken as the missing text content and recorded, so that the hearing of the tested person is further analyzed according to the missing text content in the following.

For example, the first speech test text content may be "stool", the text content of the speech signal may be "board x", the missing text content is "stool", and part of the syllables in "deng" cannot be recognized.

It should be noted that the missing text content refers to the expression of the missing syllable of the first speech test result in the above embodiment. For example, the missing text content may be a "stool" and the further missing text test content associated with the pronunciation of the missing text content may be "big", "but", "cold", "very", to further confirm that "d efng" identifies the wrong syllable detail.

It can be appreciated that the terminal device generating the second verbal test instruction can cause the headset to generate and play the second verbal test audio according to the second verbal test instruction.

And S702, transmitting the second speech test instruction to the earphone.

And S703, acquiring a second speech test voice signal of the tested person and missing text test content transmitted by the earphone.

The second speech test voice signal is a signal sent by the testee reading the missing text content played by the earphone.

Step S704, if the text content of the second speech test voice signal of the tested person is identified to be inconsistent with the missing text content, taking the syllables of the missing text content as missing syllables and recording the syllables.

It can be understood that if the text content of the second speech test voice signal for identifying the tested person is not consistent with the missing text test content, the syllable of the missing text content is further confirmed to be the missing syllable of the tested person with hearing loss, and the hearing loss of the tested person is further confirmed.

For example, the missing text test content may be "etc", and the missing syllable is a part or all of the "deng".

Step S705, generating a second speech test result according to the missing syllables.

It will be appreciated that the subject's hearing may then be further analyzed based on the second speech test results. For example, the missing syllable may be "deng", and the hearing of the subject may be measured subsequently by the text content including the "d" syllable and the text content including the "eng" syllable, so as to further measure the frequency band in which the hearing loss exists in the subject.

In some embodiments, the analysis of the partial frequency bands with hearing loss of the testee can be continued according to the second speech test result.

In the embodiment of the application, the terminal device can further confirm the missing text content of the first speech test result based on the first speech test text content, take the confirmed missing text content as the missing syllable, and generate the missing second speech test result according to the missing syllable, thereby achieving the effect of effectively utilizing the first speech test result of the testee.

Step 903, the terminal device obtains the voice signal of the testee and the first speech test text content output by the earphone, if the text content of the voice signal of the testee is identified to be inconsistent with the first speech test text content, the part, which is inconsistent with the text content of the voice signal, in the first speech test text content is used as missing text content and recorded, and a first speech test result is generated according to the missing text content.

The text content of the first speech test may be a bench, the text content of the voice signal may be a board x, and the missing text content is a bench and cannot be recognized by a part of syllables in the deng.

And 904, generating a second speech test instruction by the terminal equipment according to the missing text content, and transmitting the second speech test instruction to the earphone.
