Hearing is one of the most important senses in human beings. This is because it gives us alerts on dangers that we cannot see. Many thanks to the science and technology for introducing hearing aids. These devices can help many people who suffer from hearing complications. Outlined in this article is how these devices work.
First of all, you should bear in mind that these devices come in two types: analogue and digital. These two do not work the same, although they have similar components, which include microphone, amplifier, microchip, battery and receiver.
Microphone is placed on the outside of the hearing aid and its work is to pick up sound from air as it enters the ear. It then converts the sound waves into digital signals. The amplifier is used to strengthen the digital signals. Speaker converts those signals into some vibrations, which then passes through the inner ear straight to the brain. The minute battery provides power to the hearing aid while microchip helps in tuning and personalizing the device to your needs.
For the analogue one, it picks up sound and translates it into an electrical signal. It then amplifies it and feeds it into the ear. Some of the analogue hearing aids are able to detect whether the sound is loud or low, and thus whether or not it needs to be amplified.
Digital hearing aid is far much advanced as compared to the analogue one. It has a silicon chip that comprises of millions of electrical components, which continually process the incoming sound. It converts the sound into a clearer and more audible sound level into the ear. Due to its sophistication, it is able to distinguish between sound that need to be amplified and that does not require any amplification. These ones contain several pre-set programs, which can be used in different environments, such as concerts, quiet conversations, or at occasions where there is a lot of background noise.
Sophisticated digital hearing aids naples fl enable users to watch the television while taking part in conversations. They are able to locate where sound is coming from or eliminate whistling while on the phone. They can also link up through wireless technology to the television, mobile phone or computer. In a nutshell, a hearing aid takes up sound that enters into the ear and processes it to match the hearing loss. Then, it releases the signal back into the ear and all this is done instantaneously.
