Recognizing that you have hearing loss can be difficult and overwhelming. Add to that the many choices of hearing aids available, the various style selections, the steps to go through to get one, and you have quite a lot of thinking to do. On top of that, many times the technology behind the hearing aid is the last overwhelming factor for senior citizens.

How do these things work? Technology in general can be difficult for some mature adults to grasp, and when it comes to hearing aids, even the most savvy person sometimes does't understand the mechanics behind the device that helps them hear.

All hearing aids have the same basic mechanics, parts, and functions. Styles, colors, sizes and features vary, but the general concept is the same.

First, all hearing devices in the form of a hearing aid have a microphone. The microphone receives the sound in the room and passes it through to the amplifier. Most hearing aids come with a standard microphone, but you can also opt to get a hearing aid with a directional microphone, which helps to pick up sound only from right in front of you. This would help reduce background noise & let you focus on a person speaking directly to you.

The amplifier increases the volume of the sound. In some hearing aids, the process of amplifying sound is accompanied by features that reduce background noise and purify the sound, so that you can hear voices more clearly.

After the sound is received by the microphone and then amplified to be louder & more easily heard, it is passed through the speaker so that you can hear it. The speaker's job is simple - it delivers sound from the amplifier into your ear.

And the last piece that ever hearing aid has is a battery. The battery 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.

Digital hearing aids, for example, include more features and have more ability to deliver better sound to your ear, but require more battery power, meaning you have to change the batteries out more often.

Ultimately, the selection for hearing aids is broad, but all hearing aids include a microphone, amplifier, speaker, and battery. These four units are the basic mechanics for helping you hear better than you did before.
