Description

Technical Field

[0001] The present invention relates to the field of hearing aids, in particular to a hearing aid self-fitting method. Background Art

[0002] A hearing aid is a small loudspeaker that amplifies sounds that are originally inaudible, and then uses the hearing-impaired person's residual hearing to send the sounds to the auditory center of the brain, so that the person can feel the sounds, bringing great convenience to the hearing-impaired. A hearing aid mainly consists of five parts: microphone, amplifier, receiver, power supply and volume control. The amplifier in the hearing aid amplifies the received sound and then inputs it into the ears of the hearing-impaired person, making the sound heard by the hearing-impaired person clear and loud.

[0003] Hearing aids need to be fitted before use. Through fitting, hearing-impaired patients can choose suitable hearing aids. However, the audio of existing hearing aids uses a unified audio signal. Different audio will produce different effects when transmitted to the ears of different patients. This will cause some hearing-impaired patients to not get a perfect hearing experience. In addition, the microphone and speaker of the hearing aid are prone to damage during use. When the microphone and speaker are damaged, the audio heard by the patient will change, which will cause the sound emitted by the speaker to change, which can easily mislead. Summary of the invention

[0004] In view of the problems in the prior art, the present invention provides a hearing aid self-fitting method.

[0005] The technical solution adopted by the present invention to solve the technical problem is: a hearing aid self-fitting method, comprising the following steps: (1) First, the self-fitting function of the hearing aid is activated. The hearing aid outputs a digital signal, which is converted into an electrical signal through a digital-to-analog converter. The electrical signal is then output through a speaker, causing the speaker to output a sound for detection. The detection sound is then received by a microphone, which then inputs the received sound into a digital-to-analog converter and converts it into a digital signal. (2) Input the digital signal into the detection chip to detect the digital signal. By detecting the difference between the digital signal and the detection digital signal through the detection chip, it can be tested whether the speaker of the hearing aid can make sound correctly, so that the audio detection of the speaker can be performed; (3) The hearing-impaired patient then puts on the hearing aid, controls the external playback device to play an audio clip, and then receives the audio clip through the microphone of the hearing aid. The audio clip is then emitted through the speaker inside the hearing aid, and then the sound is transmitted to the ear of the hearing-impaired patient. The hearing-impaired patient then speaks the repeated sound, and then the sound output by the hearing-impaired patient is received through the microphone of the hearing aid. (4) Compare the digitally converted sound output by the hearing-impaired patient with the sound received by the speaker microphone, so that the difference between the sound heard by the hearing-impaired patient and the output audio can be distinguished, and then the different audios are adjusted until the detected audio and the audio output by the patient maintain a high degree of similarity, so that suitable hearing aids can be adjusted for different patients; (5) When hearing-impaired patients who cannot speak are undergoing audio testing, text is displayed in front of the patients at the same time. The hearing-impaired patients will hear the parts of the audio that are significantly different, and then adjust the audio with these differences until the tested audio maintains a high degree of similarity with the audio output by the patient. Ultimately, the sound heard by the hearing-impaired patients after wearing hearing aids is clear and accurate.

[0006] Specifically, the speaker detects audio and selects multiple groups of sounds with large sound frequency fluctuations. During detection, the audio signal is directly input into the speaker through the control chip inside the hearing aid for playback.

[0007] Specifically, the detection chip compares the two sets of audio signals output and input by the speaker and the microphone, and performs self-test during the use of the speaker.

[0008] Specifically, when adjusting the audio, the hearing aid will make fine adjustments for commonly used characters to prevent the patient from being troubled by unclear sounds emitted by the hearing aid.

[0009] Specifically, when the microphone receives an audio signal, it converts the audio signal into a digital signal, and then compares the digital signal with the emitted audio signal, so that the audio accuracy of the microphone can be synchronously detected.

[0010] Specifically, the hearing aid will record all received and output audio signals for a period of time after being worn, and then the hearing-impaired patient will record all audio signals with errors based on the sounds heard in daily life, so as to facilitate subsequent maintenance and adjustment.

[0011] Beneficial effects of the present invention: (1) The present invention provides a hearing aid self-fitting method, wherein a digital signal is output from the hearing aid, the digital signal is converted into an electrical signal through a digital-to-analog converter, and then the electrical signal is output through a speaker, so that the speaker outputs a detection sound. After the detection sound is emitted, it is received by a microphone, and the microphone inputs the received sound into the digital-to-analog converter to convert it into a digital signal, and then the digital signal is input into a detection chip to detect the digital signal. The detection chip detects the difference between the digital signal and the detection digital signal, so that it can be checked whether the speaker of the hearing aid can emit sound correctly.

[0012] (2) The hearing aid self-fitting method described in the present invention can distinguish the difference between the sound output by the hearing-impaired patient and the sound received by the speaker microphone by digital conversion, and then adjust the different audio until the detected audio and the audio output by the patient maintain a high degree of similarity. In this way, suitable hearing aids can be adjusted for different patients. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] The present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0014] Figure 1 The present invention provides a flowchart of a hearing aid self-fitting method. Implementation

[0015] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0016] like Figure 1 As shown, a hearing aid self-fitting method according to the present invention comprises the following steps: (1) First, the self-fitting function of the hearing aid is activated. The hearing aid outputs a digital signal, which is converted into an electrical signal through a digital-to-analog converter. The electrical signal is then output through a speaker, causing the speaker to output a sound for detection. The detection sound is then received by a microphone, which then inputs the received sound into a digital-to-analog converter and converts it into a digital signal. (2) Input the digital signal into the detection chip to detect the digital signal. By detecting the difference between the digital signal and the detection digital signal through the detection chip, it can be tested whether the speaker of the hearing aid can make sound correctly, so that the audio detection of the speaker can be performed; (3) The hearing-impaired patient then puts on the hearing aid, controls the external playback device to play an audio clip, and then receives the audio clip through the microphone of the hearing aid. The audio clip is then emitted through the speaker inside the hearing aid, and then the sound is transmitted to the ear of the hearing-impaired patient. The hearing-impaired patient then speaks the repeated sound, and then the sound output by the hearing-impaired patient is received through the microphone of the hearing aid. (4) Compare the digitally converted sound output by the hearing-impaired patient with the sound received by the speaker microphone, so that the difference between the sound heard by the hearing-impaired patient and the output audio can be distinguished, and then the different audios are adjusted until the detected audio and the audio output by the patient maintain a high degree of similarity, so that suitable hearing aids can be adjusted for different patients; (5) When hearing-impaired patients who cannot speak are undergoing audio testing, text is displayed in front of the patients at the same time. The hearing-impaired patients will hear the parts of the audio that are significantly different, and then adjust the audio with these differences until the tested audio maintains a high degree of similarity with the audio output by the patient. Ultimately, the sound heard by the hearing-impaired patients after wearing hearing aids is clear and accurate.

[0017] Specifically, the speaker detects audio and selects multiple groups of sounds with large frequency fluctuations. During detection, the audio signal is directly input into the speaker through the control chip inside the hearing aid for playback. By detecting multiple groups of sounds with large frequency fluctuations, the accuracy sensitivity of the speaker can be detected.

[0018] Specifically, the detection chip will compare the two sets of audio signals output and input by the speaker and microphone, and perform self-tests during the use of the speaker, so that problems with the speaker and microphone can be detected in a timely manner.

[0019] Specifically, when the hearing aid adjusts the audio, it will make fine adjustments for commonly used words to prevent the sound emitted by the hearing aid from being unclear and causing distress to the patient. By checking the commonly used words, the commonly used words of the hearing aid will not be incorrectly emitted, which can improve the user experience of hearing-impaired patients.

[0020] Specifically, when the microphone receives an audio signal, it converts the audio signal into a digital signal, and then compares the digital signal with the emitted audio signal, so that the audio accuracy of the microphone can be synchronously detected.

[0021] Specifically, the hearing aid will record all received and output audio signals for a period of time after being worn. The hearing-impaired patient will then record all audio signals with errors based on the sounds they hear in daily life, which facilitates subsequent maintenance and adjustments. Through continuous adjustments, the hearing-impaired patient can continuously optimize during use and continuously improve the accuracy of the hearing aid use.

[0022] When in use, first start the self-fitting function of the hearing aid, and the hearing aid will output a digital signal. The digital signal is converted into an electrical signal through the digital-to-analog converter, and then the electrical signal is output through the speaker, so that the speaker outputs the detection sound. After the detection sound is emitted, it is received by the microphone, and the microphone inputs the received sound into the digital-to-analog converter to convert it into a digital signal. The digital signal is input into the detection chip to detect the digital signal. The detection chip detects the difference between the digital signal and the detection digital signal, so that it can be checked whether the speaker of the hearing aid can make a sound correctly. In this way, the speaker can be tested for audio, and then the hearing-impaired patient completes the wearing of the hearing aid, controls the external playback device to play a piece of audio, and then receives the audio through the microphone of the hearing aid. The audio is emitted through the speaker inside the hearing aid, and then the sound is transmitted to the hearing-impaired person. In the patient's ear, the hearing-impaired patient speaks the repeated sound, and then the sound output by the hearing-impaired patient is received through the microphone of the hearing aid. The sound output by the hearing-impaired patient is compared with the sound received by the speaker microphone through digital conversion. In this way, the difference between the sound heard by the hearing-impaired patient and the output audio can be distinguished, and then these different audios are adjusted until the detected audio and the audio output by the patient maintain a high degree of similarity. In this way, suitable hearing aids can be adjusted for different patients. When the hearing-impaired patient who cannot speak is undergoing audio testing, the text is simultaneously displayed in front of the patient. After the hearing-impaired patient hears the audio, there are large differences. Then these different audios are adjusted until the detected audio and the audio output by the patient maintain a high degree of similarity. Finally, the sound heard by the hearing-impaired patient after wearing the hearing aid is clear and accurate.
