There are approximately 1,000 hearing aid models that are available in the market today. To help you choose the right kind of hearing aid, you need to study first how hearing aids work. Understanding the basic principles of how do hearing aids work is very important so that you will know what this device can or cannot do for you.
The Basic Principles
To answer the question how do hearing aids work, we need to first look into the nature of these devices. Hearing aids have built in microphone that capture sounds. This microphone is so sensitive that it can pick up sound waves from a certain distance. Aside from having a microphone, the hearing aid is also fitted with sound amplifier. The amplifier increases the volume of the sound captured by the microphone.
While a hearing aid amplifies sound, it does not necessarily improve the quality of the sound. Aside from the microphone and the amplifier, your hearing aid also has a built in speaker that sends the sound into your auditory canals so that you can hear it. The whole process of capturing, amplifying and sending the sound wave into your auditory canal takes just a few seconds. Since your hearing aid runs on batteries, you need to check your batteries regularly to make sure that your hearing aid functions well. Like any types of battery operated devices, the hearing aid will not work well with diminished power.
Understanding how hearing aids work is very crucial. You must understand that a hearing aid is just a small machine that is fitted into your ear and it cannot really duplicate the same sound that people of normal hearing hear. This means that if you are wearing a hearing aid, you can expect to experience disruptions and distortions in the sound that you hear. This does not mean that a hearing aid is an unreliable piece of equipment, but they do have their limitations.
