What is a "hearing aid"?
A hearing aid is a small electronic device worn inside or behind the ear to make sounds louder for individuals with hearing loss. It includes a microphone that picks up sound, a device that increases the volume of the sound, and a speaker that delivers the louder sound into the ear. Hearing aids are designed to improve hearing by making sounds clearer and louder, helping people with hearing difficulties to communicate more effectively and participate more in daily activities. They come in various styles and technologies to suit different types and degrees of hearing loss.
