[0002] A hearing aid is a small amplifier that amplifies sounds that are otherwise inaudible, allowing the residual hearing of the hearing-impaired person to transmit the sound to the auditory center of the brain, thus enabling them to perceive the sound. It brings great convenience to the hearing-impaired. Hearing aids mainly consist of five parts: a microphone, amplifier, earpiece, power supply, and volume control. Hearing aids are classified according to their conduction method into air conduction hearing aids and bone conduction hearing aids; and according to their usage method into body-worn, eyeglass-style, clip-on, behind-the-ear, in-the-ear, in-the-canal, and fully-in-the-canal hearing aids.

[0003] After the hearing aid is assembled, it needs to be tested. The testing of hearing aids is generally carried out in a hearing test room. The hearing test room needs to avoid the influence of external sounds on the hearing aid test. Most existing hearing test rooms are closed spaces pretending to be air replacement devices for hearing test operations. However, because the structure of the hearing test room is simple, the sound insulation effect is not good. Therefore, the use of the hearing test room is not good.
