Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1, fig. 1 is a schematic flow chart of an adaptive hearing parameter fitting method according to an embodiment, and the adaptive hearing parameter fitting method is applied to a hearing aid and a hearing parameter fitting device (e.g., a mobile phone terminal). After the hearing aid is switched on, the hearing parameter fitting device establishes a communication connection, such as a bluetooth communication connection, with the hearing aid, so as to perform adaptive hearing parameter fitting of the hearing aid.
The steps provided by the adaptive hearing parameter fitting method in the embodiment comprise:
In this embodiment, the preset environmental standard includes an environmental volume standard and a play volume standard, and the purpose of ensuring that the current environmental parameter meets the preset environmental standard is to enable the execution of the current adaptive hearing parameter fitting method not to be interfered by environmental noise, and to ensure that different patients can have the same test standard, thereby avoiding unnecessary differences in the adaptive hearing parameter fitting process.
In one embodiment, it is ensured that the current ambient volume meets the ambient volume criteria. Specifically, an ambient volume threshold, which is an allowable ambient noise test range, is preferably obtained, and is specifically set to 40dB, for example. Further, collecting the current environment volume, and prompting a user to test in a quiet environment when detecting that the current environment volume is greater than an environment volume threshold value; and when the current environment volume is detected to be less than or equal to the environment volume threshold value, determining that the current environment volume meets the environment volume standard. It will be appreciated that the accuracy of the hearing test is ensured by ensuring that only subsequent steps are performed when the current ambient volume meets the ambient volume criteria, avoiding noise interference.
In one embodiment, it is ensured that the current device volume meets the playback volume criteria. Specifically, the user is prompted to adjust the volume of the mobile phone to a specific volume, for example, the maximum volume of the current device, on the parameter matching interface. And when the volume of the current equipment is detected to be equal to the preset volume reference, determining that the volume of the current equipment meets the playing volume standard. The purpose of this particular embodiment is to: the volume of the mobile phone is adjusted to the same volume reference, so that the situation that the user performs hearing tests at different volume levels to influence the hearing test result is prevented.
In this embodiment, a test of playing audio at a plurality of preset target frequency points needs to be performed, where the current target frequency point is any one of the plurality of preset target frequency points. Illustratively, when the current environmental parameter is detected to meet the preset environmental standard, the hearing parameter verifying device generates a left channel pure audio stream with the frequency of 1000Hz and the volume of 50dB, and transmits the left channel pure audio stream to the hearing aid of the left ear through the bluetooth module, and the hearing aid plays the pure audio stream through the receiver.
And 104, acquiring user feedback information, adjusting the first preset volume according to the user feedback information, and acquiring a target listening threshold of the currently played audio after adjustment.
In this embodiment, the user feedback information includes first user feedback (inaudible) and second user feedback (inaudible). The target listening threshold refers to the minimum audio volume that the user can hear at the current target frequency point.
In a specific embodiment, initial feedback information of a user is obtained, and when the initial feedback information is feedback of a first user, it is indicated that a hearing threshold of the user at the current target frequency point is above a first preset volume. Therefore, the first preset volume is increased by the first change value, and the subsequent feedback information of the user is received. Illustratively, the first variation value is 5dB, thus controlling the hearing aid to play a pure tone with an intensity of 55 dB. When the subsequent feedback information is the second user feedback, the target listening threshold of the user is found, and 55dB is used as the target listening threshold. And when the subsequent feedback information is the first user feedback, indicating that 55dB is still too light for the user, repeating the steps of increasing the first preset volume by the first change value and receiving the subsequent feedback information of the user until the subsequent feedback information is the second user feedback. For example, when a pure tone with an intensity of 70dB is played, a second user feedback is received, with 70dB as the target listening threshold.
Correspondingly, when the initial feedback information is the feedback of the second user, it indicates that the hearing threshold of the user at the current target frequency point is below 50dB, so that the first preset volume is reduced by the second change value, and the subsequent feedback information of the user is received. Illustratively, the second variation value is 10dB, thus controlling the hearing aid to play a pure tone with an intensity of 40 dB. When the subsequent feedback information is fed back by the second user, the first preset volume still needs to be reduced, the steps of reducing the first preset volume by the second change value and receiving the subsequent feedback information of the user are repeatedly executed until the subsequent feedback information is fed back by the first user. Illustratively, the first user feedback is received, for example, when the hearing aid is controlled to play a pure tone with an intensity of 30dB, which indicates that the hearing threshold of the user at the current target frequency point is above 30B. Further, the step of increasing the first preset volume by the first variation value is repeatedly performed, i.e. the hearing aid is controlled to play a pure tone with an intensity of 35 dB. And receiving the subsequent feedback information of the user until the subsequent feedback information is fed back by the second user. For example, when the current first preset volume is 35dB, the second user feedback is received, and then 35dB is taken as the target listening threshold.
And 106, taking the next preset target frequency point in the plurality of preset target frequency points as the current target frequency point, and executing the step of generating the current playing audio with the first preset volume at the current target frequency point and the subsequent steps until the target listening threshold of the preset playing audio at each preset target frequency point is obtained.
In this embodiment, the preset target frequency points include 8 target frequency points of 1000Hz, 1500Hz, 2000Hz, 2500Hz, 3000Hz, 4000Hz, 500Hz, and 250Hz, and the target frequency points set by the left and right hearing aids are consistent. The testing method of other target frequency points is the same as the testing method of 1000Hz, and is not described herein.
Furthermore, a hearing test report of the target user is generated according to a target hearing threshold value of the preset playing audio at each preset target frequency point. The content of the hearing test report can comprise a drawing generated audiogram and the hearing loss condition of the target user. Specifically, the International health organization (WHO-1997) ranks hearing loss as normal with an average hearing loss of 25 dB or less; the average hearing loss is between 26 and 40 decibels and is mild hearing loss; the average hearing loss is between 41 and 60 decibels, and the hearing loss is moderate; the average hearing loss is 61-80 decibels, and the hearing loss is severe; the average hearing loss of 81 db or more is a very severe hearing loss.
And 108, acquiring a standard listening threshold value, calculating a gain parameter corresponding to each preset target frequency point according to the standard listening threshold value and the target listening threshold value, and generating a fitting parameter file according to the gain parameter corresponding to each preset target frequency point.
The standard listening threshold refers to the minimum audio volume that a normal person can hear, and is usually set to 20 dB. The gain parameter refers to the audio increment at each preset target frequency point.
In one embodiment, for example, the target hearing threshold value at 1000Hz frequency point is 60dB through testing, and the difference between the standard hearing threshold value and the target hearing threshold value is calculated, i.e. the difference is 40 dB. Further, gain coefficients are obtained. The gain factor refers to the increase ratio of the gain required for comfortable hearing in case of sensorineural deafness, and 1/2 is adopted in this embodiment as the hearing loss increases. And finally, calculating the product of the gain coefficient and the difference value, namely the product is 20dB, and taking the 20dB as the gain parameter of the corresponding 1000Hz preset target frequency point. The calculation of the gain parameters of other preset target frequency points of the left ear and the right ear of the user is the same as the method, and is not described herein again. And finally forming a hearing test parameter file suitable for the user after the calculation of each preset target frequency point.
And step 110, sending the fitting parameter file to the hearing aid so that the hearing aid performs performance configuration work according to the fitting parameter file.
In a particular embodiment, the validation parameter file is also subjected to security verification. Specifically, before sending the matching parameter file, frame header data, accumulation and check codes and frame tail data are added to the matching parameter file of the left ear and the right ear according to a preset communication protocol, so as to form a command for writing in the matching parameter file. After the matching parameter file is respectively transmitted to the left ear hearing aid and the right ear hearing aid through Bluetooth communication, a processor in the hearing aid checks whether the accumulation and check code accords with the accumulation value of the command according to whether the frame header data and the frame tail data in the written command are data required by a preset communication protocol. If the verification parameters are all in accordance with the verification parameters, the verification parameter file is determined to be a legal file. Further, whether the gain parameter of each preset target frequency point in the fitting parameter file is within the maximum support range is checked. If the requirements are all met, the matching parameter file can be judged to be an executable file, and the processor stores the matching parameter file into the memory so as to be called in work.
The fitting parameter file is an executable file of the hearing aid, and the hearing-impaired patient can experience the optimal hearing-aid effect based on the fitting parameter file, so that the purpose of adjusting hearing parameters is achieved.
According to the self-adaptive hearing parameter fitting method, the target hearing threshold values of the user at different preset target frequency points are detected, and the gain parameters at different preset target frequency points are obtained according to the target hearing threshold values, so that a fitting parameter file is formed, the hearing parameters of the hearing aid are adjusted, and hearing-impaired patients can experience the optimal hearing aid effect. Therefore, the invention greatly reduces unnecessary time expenditure and cost expenditure in the hearing parameter fitting process of hearing impaired people.
In order to better explain the adaptive hearing parameter fitting method, a specific application scenario is described below in combination with the above embodiment, where the hearing parameter fitting device is exemplified by a mobile phone:
when a user needs to perform hearing parameter verification, firstly, an App software for verification is downloaded and installed on a mobile phone of the user. After a user starts the hearing aid, the Bluetooth function of the mobile phone needs to be synchronously opened, surrounding Bluetooth devices are searched in a connection interface in the App, and the hearing aid needing to be checked and matched is clicked to be connected, so that communication connection with the hearing aid is achieved. The Bluetooth connection is based on BLE (Bluetooth Low Energy) communication, so the influence on the power consumption of the hearing aid is small.
When the hearing parameter is verified, the user needs to click back to the function page in the App and enter the audiometric function interface. The App collects and detects the ambient noise, and when the ambient noise is detected to be too high, the App reminds the user to test in a quiet environment. And when detecting that the ambient noise is reduced to an allowable range, the App allows the user to click to enter a 'prompt mobile phone volume' interface in the next step. In the interface of prompting the volume of the mobile phone, the App reminds the user to adjust the volume of the mobile phone to the maximum sound, or the user clicks the next step, and the App automatically adjusts the volume of the mobile phone to the maximum sound. The volume of the mobile phone can be adjusted to a specific volume through the adjustment, so that the user is prevented from conducting hearing tests under different volume levels.
The user clicks the next step and enters a test interface where a hearing test is performed at 8 frequency points including 1000Hz, 1500Hz, 2000Hz, 2500Hz, 3000Hz, 4000Hz, 500Hz and 250 Hz. Firstly, a hearing test of 1000Hz is carried out, an App generates a left sound channel pure tone with the frequency of 1000Hz and the volume of 50dB, a mobile phone transmits the pure tone to a hearing aid of a left ear through Bluetooth, and the hearing aid plays the audio stream through a loudspeaker.
At this time, the user cannot hear the sound initially, which indicates that the hearing threshold of the user at the frequency point is above 50dB, and the user cannot hear the sound through the button feedback in the App page. And the App plays the next pure tone with the intensity of 55dB, if the user can hear the pure tone at the moment, the test is successful, and the hearing threshold value of the user at the frequency point of 1000Hz is 55 dB. If the user still cannot hear at 55dB, the test is not successful, and the test is continuously increased by 5dB to 60 dB. And so on until the hearing threshold of the user at the 1000Hz frequency point is obtained.
Of course, if a pure tone with a volume of 50dB is played, it may be possible for the user to hear the sound at the beginning, which indicates that the user's hearing threshold at the 1000Hz frequency point is below 50 dB. At this time, App reduces the volume by 10dB, and then the App plays the next pure tone with the intensity of 40 dB. The user continues to adjust down by 10dB to 30dB if he can still hear it. At this time, if the user cannot hear the sound when the pure tone having the volume level of 30dB is played, the volume level is increased by 5dB, and the pure tone of 35dB is played. If the user can hear, the hearing threshold of the user at the 1000Hz frequency point is 35 dB. If the user can not hear, the hearing threshold of the user at the 1000Hz frequency point is 40 dB.
The above only describes the hearing test procedure at a frequency point of 1000 Hz. In the application scenario, the hearing tests are continuously performed on the remaining 7 frequency points of 1500Hz, 2000Hz, 2500Hz, 3000Hz, 4000Hz, 500Hz and 250Hz in sequence. The test method for other frequency points is the same as the test method for 1000 Hz.
The hearing test of the left ear of the user at 8 frequency points is completed through the test steps, and the hearing threshold of the left ear of the user at the 8 frequency points can be obtained. Then, the hearing test of the right ear is performed, and the test method is the same as that of the left ear, which is not described again.
The hearing test for the user is completed through the hearing tests at different frequency points. The App generates hearing test reports according to the hearing thresholds of the left ear and the right ear of the user at 8 frequency points. The user can view the report to learn about his or her hearing loss.
On the page of the hearing test report, the App prompts the user that automatic fitting can be performed. The user can perform automatic fitting after selecting the function. For example, the target hearing threshold value at the 1000Hz frequency point is 60dB through testing, and the difference value between the standard hearing threshold value and the target hearing threshold value is calculated to be 20dB, so that the difference value is 40 dB. The gain factor is then obtained. The gain factor refers to a ratio of gain increase required for comfortable hearing due to sensorineural deafness, and is set to 1/2, for example, as the degree of hearing loss increases. And finally, calculating the product of the gain coefficient and the difference value, wherein the obtained product is 20dB, and taking the 20dB as the corresponding gain parameter of the 1000Hz preset target frequency point. The calculation of the gain parameters of other preset target frequency points of the left ear and the right ear of the user is the same as the method, and is not described herein again. And finally forming a hearing test parameter file suitable for the user after the calculation of each preset target frequency point.
And the App transmits the fitting parameter file to the hearing aid through Bluetooth. The processor in the hearing aid checks whether the file is a legal file, and if the file is a legal file, the file is written into a Digital Signal Processing (DSP) chip in the hearing aid. The DSP will work with the newly written parameters to adapt to the hearing loss situation of the user.
