How Do Hearing Aids Work?

hearingDo you know how hearing aids work? Do they restore hearing? The answer is hearing aids don’t actually restore your hearing, but they help you overcome the loss by amplifying the sounds you pick up. Technological advances coupled with innovative thoughts of different manufacturers help hearing devices work in a way that help you to overcome your hearing difficulties and stay in style at the same time. Siemens hearing instruments are quite stylish and dead useful.

Granted these devices are expensive little devices, but the kind of role they play greatly justifies their cost. If cosmetic concerns are the biggest problem, there are modern in-the-ear designs that are so concealed, that they are impossible to see.

Different Parts of Hearing Aids

Let us know about different parts of these devices and then we will go to a more elaborate discussion of how hearing aids work. While there are different kinds of hearing aid styles, the features they all share are common.

Regardless of the degree of hearing loss the aid corrects, it will have

  • An amplifier
  • A receiver
  • A microphone
  • An on/off switch
  • A power source, provided by a replaceable battery

How Hearing Aids Work? The Working Mechanism

  • Hearing aids have an easy working mechanism.
  • The microphone picks up sounds from the environment and conducts it into an electrical signal.
  • This signal is then transmitted to the amplifier, which increases the volume of the sound and sends it to the receiver.
  • hearing-1Also called the speaker, the receiver converts the signal back to sound and sends it to the ear.
  • The signal is converted to a sound signal and sent to the brain through the auditory nerve.
  • The hearing aids are able to filter out the signals that are interpreted as noise.
  • This makes it possible to use the hearing aids in public places where diverse environmental noises may get in the way of conversation.

The simple design of the hearing aids is reflected in the simple method through which they work. This is not to say that the mechanics or electrical of the hearing aids have not evolved. Technology has caught up with them, and in attempt to get more minimalist designs, the arts have become digital, allowing an even more complex manipulation of the signals being received.

This makes it possible to tailor make the hearing devices for people suffering the different types, and degrees of hearing loss. Additionally, hearing aids have been made to be more versatile, allowing their compatibility with telephones, when a telecoil is included in the design, and with wireless hearing aids, such as FM listening systems. It has made life more convenient for those with hearing loss, as these capabilities were previously not available.

earsThe whole process is powered by a battery, as these aids have electrical components. While there are cases of aids having rechargeable batteries, most of them use replaceable ones. They are affordable, and they last for a couple of days before needing replacement. There are disposable hearing aids as well, for those who dislike the maintenance chores that include battery replacement and cleaning.

Preventing the Occlusion Effect

In the ear hearing aids occupy space in the outer part of the ear canal, leading to a resonation of their own sounds. This design shortcoming is overcome with over the ear hearing aid styles which free up as much canal space as possible.
