When a person has hearing loss and cannot be treated, he/she needs to wear a hearing aid as soon as possible to protect the residual hearing. A hearing aid is a miniature sound reinforcement device that amplifies sound from the outside world to the extent that a hearing loss patient needs. Using the patient’s residual hearing to compensate for hearing loss, so that hearing loss patients can hear the same sound as normal people, is the most effective tool to help patients with ear disease improve their hearing so far.

One such magical thing, naturally someone will be curious about how it works, and many people don’t know much about how it works. I am curious as to how small it is to help patients hear the sound? This just proves that “the sparrow is small and complete.” Hearing aids mainly consist of microphones, magnifiers, receivers, batteries and various volume tone knobs. Its principle is that the acoustic signal is converted into an electrical signal through a microphone, and then amplified by an amplifier, and finally the electrical signal is restored by the receiver to an acoustic signal and transmitted to the human ear.
