The Ins and Outs of a Hearing Aid
Hearing aids are very small, electronic devices that fit in the outer ear of an individual within the ear canal, or sometimes, behind the ear. The hearing aid has a main function – which is to make sound clearer and louder in a comfortable way.
Components of a hearing aid
When making a purchasing decision on hearing aids, one needs to look at the parts. On a hearing aid, there are tubes and receivers. Tubes are more cost effective than receivers, but are limited in the function. The receiver tube places the speaker into the ear, and the tube allows sound to go through it to ear canal. Maintaining the receiver is complex – more complex than maintenance required for regular tubes. Receivers provide better sound quality and they are also pretty connected to moisture damage. Maintenance is simple for the regular tube.
The parts of a hearing aid are easy to understand. Most of the parts of the hearing aid revolve around amplifying sound. There is one or more microphones to gather sound, an amplifier to process a wide range of sounds, a receiver or speaker for transmitting sound from the amplifier to the ear and a battery to keep the process going.
A lot of today's hearing aids – or at least the most complex – have a microscopic coating that is bounded to the inner circuitry and outer casing. The workings of a hearing aid are encompassed into coverings known as shells. Shells come in a variety of shapes, styles and colors to fit the user's hearing loss, daily routine and needs.
Along with those common parts of a hearing aid, today's new digital devices include a small computer that is programmed to make the signals fit the hearing loss of the individual user. Hearing aids do offer remote control that is used for making adjustments and users with dexterity issues.
Hearing aids function similarly to mini-computers as one researcher said – mini-computers for your ears. In fact, there is a lot of technology inside. You don't need to understand how the technology works as long it works and you hear. It is important to understand the parts.
Hearing aids won't restore your hearing to where it was before you started having problems. Of course, they do help you in improving the hearing by making soft sounds louder and help you with hearings sounds you are having trouble with. Understanding the parts of the hearing aid as mentioned in previous paragraph will assist in making your experience with hearing aids a positive one.
