A hearing aid is a small electronic device that is designed to amplify sound for individuals who have hearing loss. It works by capturing sound waves through a microphone, converting them into electrical signals, and then amplifying those signals before sending them into the ear canal. The amplified sound helps individuals with hearing loss to hear better and improve their communication abilities. There are different types of hearing aids available on the market, including behind-the-ear (BTE), in-the-ear (ITE), in-the-canal (ITC), and completely-in-the-canal (CIC) devices. Choosing the right type of hearing aid depends on the severity of hearing loss, personal preference, and lifestyle needs.
