Providing Latest Digital Hearing Aid Devices in Dehradun, Uttarakhand

A hearing aid is a small electronic device that you wear in or behind your ear. It makes some sounds louder so that a person with hearing loss can listen, communicate, and participate more fully in daily activities. A hearing aid can help people hear more in both quiet and noisy situations. However, only about one out of five people who would benefit from a hearing aid actually uses one. A hearing aid has three basic parts: a microphone, amplifier, and speaker. The hearing aid receives sound through a microphone, which converts the sound waves to electrical signals and sends them to an amplifier. The amplifier increases the power of the signals and then sends them to the ear through a speaker.

Analog and Digital Hearing Aids

What is the difference between analog and digital hearing aids?

Analog hearing aids are less common.

They make continuous sound waves louder by amplifying all sounds (speech and noise) in the same way. Some analog hearing aids have a microchip to store multiple program settings used in different listening environments, such as in a quiet place (library) or in a noisy place (restaurant or soccer field). As the listening environment changes, the hearing aid settings may be changed by pushing a button on the hearing aid.

Digital hearing aids are more common.

They have all the features of analog programmable aids, but they convert sound waves into digital signals and produce an exact duplication of sound. Microchips in digital hearing aids analyze speech and other environmental sounds and store multiple program settings. The digital hearing aids allow for more complex sound processing during the amplification process which may improve performance in certain situations, such as background noise and whistle reduction. They also have greater flexibility in hearing aid programming so the sound they transmit can be matched to the needs for a specific pattern of hearing loss.
