What You Should Know About The Directional Microphone Functionality In A Hearing Aid

Analog hearing aids have grown in popularity as years pass and have been easily available for many years. These devices have a microphone that collects sounds and convert them to electrical energy; an amplifier to increase the volume of the energy as well as receivers that convert the energy to sounds. An analog hearing aid works by amplifying sounds without making it too loud; a simple enough process when you get right down to it but this simple device does come with a number of advanced features. Some of the more popular hearing aid features are directional microphones. If you are a little undecided about choosing analog hearing aids with directional microphones, a close look at this feature can help you decide whether or not it is beneficial for you. If so, then how does a directional microphone in a hearing aid works?

One of the most challenging situations in listening when you have hearing impairments is to understand conversation especially in noisy places. And the most efficient method of cutting down the effects of ambient noises is to use two microphones on each hearing aid you are going to wear; one for the front area of the device and one on the back. Each of these microphones give information to the processor in the hearing aid, that in turn analyzes the sound in the environment. When the analysis comes back with a heightened level of background noise, the sensitivity level of the microphone at the back of the hearing aid is reduced which means that background noises are also reduced. In a cheaper hearing aid, you can minimize the sensitivity of the microphone by pushing a button on the device or by remote control in order to reduce the level of background noise.

There are also more expensive hearing aids that have more powerful processors that can automatically reduce the sensitivity of the back microphone when the surrounding noises gets too loud. These processors would also increase the sensitivity of the rear microphone or put it back to normal levels as soon as background noises are minimized, allowing you to hear sounds coming from behind you. It is important to understand however, that directional microphones are designed to REDUCE noise, and not eliminate them so you would still be able to hear background noises, albeit significantly reduced in volume which would help you understand conversations even in crowded, noisy places. Before buying hearing aids with this feature, do study all the information you have gathered very carefully.
