Description

Technical Field

[0001] This invention relates to the field of hearing aid testing, specifically to a method for measuring the feedback path of a hearing aid. Background Technology

[0002] A hearing aid is an amplifier that increases the intensity of sound energy and transmits it into the ear with as little distortion as possible. It is an assistive device used by people with hearing impairments. Hearing aids help people with hearing disabilities improve their hearing impairment, thereby enhancing their ability to communicate with others. For people with hearing loss or weak hearing, air conduction hearing aids are often chosen. Air conduction hearing aids transmit sound through the outer ear, middle ear, and inner ear, which is also the most effective transmission method.

[0003] Existing hearing aids require feedback path measurement before use to confirm their status and prevent unstable states such as whistling when the provided gain exceeds a certain range, thus failing to meet people's normal usage needs. Therefore, it is necessary to propose a method for measuring the feedback path of hearing aids. Summary of the Invention

[0004] To address the problems in the prior art, the present invention provides a method for measuring the feedback path of a hearing aid.

[0005] The technical solution adopted by this invention to solve its technical problem is: a method for measuring the feedback path of a hearing aid, comprising a body module, a control module, a separation module, and a measurement module. The body module includes a hearing aid body and an outer ear hook. The hearing aid body includes a shell, a microphone, a radio, and a battery, a charging interface, a processor, and buttons installed inside. The outer ear hook is suspended on the outer ear and supports the hearing aid body. The control module includes a processing module, a connection module, and a control button module. The connection module connects the processing module, the control button module, and other devices. The control button module inputs operation commands by pressing buttons. The processing module receives the operation commands and then inputs them into the corresponding running module for execution. The separation module includes a rotating module, a storage module, and an expansion separation module. The rotating module is located at the bottom of the hearing aid body and is rotatably connected to the hearing aid body. The storage module is located on the outer side walls of the rotating module and can extend to both sides. The expansion separation module is provided with an expansion airbag, and a layer of sound insulation cotton is provided inside the expansion airbag. The measurement module includes an auxiliary sound receiving module and an auxiliary sound broadcasting module. The auxiliary sound receiving module and the auxiliary sound broadcasting module are respectively fixedly connected to both sides of the rotating module, and respectively assist the sound broadcaster and the sound receiver of the hearing aid in sound reception. When using, Step 1: First, rotate the rotating module. The rotating block will cause the auxiliary sound receiving module and the auxiliary sound broadcasting module to rotate. The auxiliary sound receiving module will rotate to the bottom of the hearing aid's sound broadcasting module, and the auxiliary sound broadcasting module will rotate to the bottom of the hearing aid's sound receiving module. Step 2: Then, pull out the storage module and expose the expansion partition module. Then, control the expansion partition module to expand using the control button module. The expanded partition module will cover the auxiliary sound receiving module and the hearing aid's microphone into a closed sound receiving area, and cover the auxiliary sound receiving module and the hearing aid's microphone into a closed sound receiving area, thus separating the two areas. Step 3: Control the auxiliary audio playback module to play sound within the closed sound reception area via the control button module. The sound is received by the hearing aid's microphone and then transmitted to the processing module for processing via the transmission module. The processing module then transmits the processed sound back to the audio playback module for playback within the closed sound reception area via the transmission module. The auxiliary audio playback module receives the sound, and then the sound played by the auxiliary audio playback module is compared with the sound received by the auxiliary audio playback module. The comparison result is used to determine whether the hearing aid's feedback path is normal. Step 4: After use, the expansion separator module can be retracted into the storage module and the storage module can be reset. At this time, rotate the rotating module, and the rotating block will drive the auxiliary sound receiving module and the auxiliary sound broadcasting module to rotate. The auxiliary sound receiving module will rotate to the bottom of the hearing aid's microphone, and the auxiliary sound broadcasting module will rotate to the bottom of the hearing aid's speaker, thereby assisting the hearing aid's speaker and microphone in receiving sound.

[0006] Specifically, the two storage modules are set on the outer side walls of the rotating module on both sides, and the auxiliary sound receiving module and the auxiliary sound broadcasting module are set on the outer side wall of the rotating module above the two storage modules.

[0007] Specifically, the expansion partition module is elliptical after expansion, and the auxiliary broadcasting module and the hearing aid's microphone, as well as the auxiliary radio module and the hearing aid's broadcasting module, are respectively enclosed within the two expansion partition modules.

[0008] Specifically, a layer of sound-absorbing cotton is fixedly installed on the inner wall of the hearing aid body.

[0009] Specifically, a layer of sound-absorbing cotton is fixedly connected to the inner wall of the airbag of the expansion separation module, thereby isolating the covered area from the outside to avoid external interference.

[0010] Specifically, the rotating module is equipped with a positioning component inside, which fixes the rotating module to prevent it from rotating randomly and affecting the normal use of the hearing aid.

[0011] Specifically, the auxiliary radio module, auxiliary broadcast module, radio, battery, charging interface, processor, buttons, and broadcast are connected to the processing module via a transmission module.

[0012] Specifically, the ear hook is rotatably connected to the outer shell of the hearing aid body. The ear hook can only be suspended when it is rotated open, and it will abut against the outer shell of the hearing aid body when it is folded and stored.

[0013] The beneficial effects of this invention: The method for measuring the feedback path of a hearing aid described in this invention, during normal use, uses an auxiliary sound receiving module and an auxiliary sound broadcasting module to assist the hearing aid's microphone and receiver in receiving and transmitting sound. When testing is required, the positions of the auxiliary sound receiving module and the auxiliary sound broadcasting module are swapped, and then separated and covered. The auxiliary sound broadcasting module is controlled to play sound while the hearing aid's receiver receives sound. Then, the hearing aid's receiver is controlled to play sound while the auxiliary sound receiving module receives sound. The sound played by the auxiliary sound broadcasting module and the sound received by the auxiliary sound receiving module are compared, and the comparison result is used to determine whether the hearing aid's feedback path is normal.
