A hearing aid is a small electronic device designed to amplify sound for individuals with hearing loss. It improves communication and enhances daily interactions by making sounds clearer and more audible.

How Hearing Aids Work

A hearing aid consists of three main components:

• Microphone – Captures surrounding sounds.
• Amplifier – Increases the volume of sound signals.
• Speaker (Receiver) – Sends the amplified sound into the ear.

Types of Hearing Aids

• Behind-the-Ear (BTE) – Fits behind the ear witha small tube leading to an earmold.
• In-the-Ear (ITE) – Custom-molded to fit inside the ear canal.
• Completely-in-Canal (CIC) – Nearly invisible and fits deep inside the canal.
• Rechargeable Hearing Aids – Modern devices with long battery life.

Who Can Benefit from Hearing Aids?

• People with Age-Related Hearing Loss – Presbycusis is common among seniors.
• Individuals with Noise-Induced Hearing Loss – Caused by prolonged exposure to loud environments.
• Children with Hearing Impairment – Helps in speech and language development.
