Today’s hearing aids are small, but—thanks to Beltone’s micro-processor technology— they are more powerful than ever.
Hearing aid anatomy
Hearing aids are small, lightweight electronic devices that sit in the outer ear, within the ear canal, or behind the ear—depending on the style. Their main function is to amplify sound in a natural and comfortable way.
The physical components of hearing aids include one or more microphones to gather sound, an amplifier designed to process a wide range of sounds, a receiver or speaker that transmits the sound signal from the amplifier to the ear, and a battery to fuel the process.
Beltone hearing aids are protected from the effects of daily wear by a microscopic coating that's molecularly bonded to the inner circuitry and outer casing. This increases the life and performance of hearing aids, and also reduces maintenance.
The delicate inner workings of custom hearing aids are contained inside coverings known as shells. Shells come in a variety of shapes, styles, and colors to fit the user's hearing loss, daily routine, and cosmetic needs.
