The Basics Of How Hearing Aids Work

Feb 29, 2008
Hearing loss is gradually aggravating problem in the whole of United States as the latest report from American Hearing Aid Association has indicated that more than 10 percent of the American popular is suffering from hearing loss in someway or the other. Hearing loss is a condition when sound is prevented from reaching the inner ear, resulting in blocking of the sound signals to the brain.

The one and only proficient way of fighting the menace of hearing loss is to adapt to hearing aid. There are different kinds of hearing aid available; however, all of them vary in size and design, while the fundamental function remains the same. Several components constitute the making of a hearing aid - microphone, circuit, receiver and battery.

The basic mechanism of all hearing aids irrespective of models and design is that, after the microphone accepts up sound, the circuit converts the sound waves into an electrical signal and changes it based upon computer data given by the audiologist. And to know how hearing aids work, it is essential to know the function of a circuit.

The circuit manipulates it with software that adjusts the sound waves in different perceptions. While a receiver after that converts the amplified sound back into an electrical signal to deliver the sound through the ear canal. All these functions are run by battery, which charges energy particles and supply the necessary power to the hearing aid components.

To know how hearing aids work, we have to know and understand the flow of sound through the hearing process. Sound travels in waveforms through the air, and they are gathered in by the ear and altered, before being sent to our brains to be interpreted. However, in case of hearing loss, hearing loss aids work towards amplifying sound, with the components that are guided with some form of internal or external controllers.

The microphone works by receiving the sound from any source and changes or converts it into varying electrical impulses. However, the fundamental of how hearing aids work is mainly due to the functioning of the circuit.

The circuit is mainly responsible for the amplification of the sound according to its prescribed settings. And the settings differ according to the environment in which the user is placed. Just as, circuit can maintain and reduce the loud sounds of vehicles, reduce any background sound, just amplifying the speech in any public place, etc.
