How Hearing Aids Work
hearing aids July 26th, 2010
Technology can be difficult for some mature adults to grasp. Wwhen it comes to hearing aids, even the most savvy person sometimes does’t understand the mechanics behind the device. All hearing aids have the same basic mechanics, parts, and functions, styles, colors, sizes and features vary, but the general concept is the same.
Hearing devices in the form of a hearing aid have a microphone receiving the sound in the room and passes it through to the amplifier. You can also opt to get a hearing aid with a directional microphone helping to pick up sound only from right in front of you reducing background noise & let you focus on a person speaking directly to you.
The amplifier increases the volume of the sound, the process of amplifying sound is accompanied by features that reduce background noise and purify the sound so you can hear voices more clearly. After the sound is received by the microphone and amplified, it is passed through the speaker so that you can hear it delivering sound from the amplifier into your ear.
And the last piece that ever hearing aid has is a battery that provides power to the hearing aid’s electronic parts. Most batteries last 5-7 days, but of course the exact life of the battery depends on the type of hearing aid you get. Some hearing aids require more battery power than other hearing aids to deliver better sound to your ear, but require more battery power, meaning you have to change the batteries out more often.
