subject: Some things about class D hearing aids [print this page] Hearing aids are devices that hearing impaired people need most. These devices help those people to hear the sounds that they want to hear well. Nowadays, there are various options that can be chosen when it comes to these devices.
There are three main parts in hearing aids that you should know. They are amplifiers, receivers and microphones. In this case, the parts that make the sounds louder are the amplifiers. Amplifiers take the signal that is sent by receiver. In this case, there are some classes of amplifiers that you should know. They are class A, class B, class D, Sliding Class A and Digital.
From those classes, you will find that the most complicated class but great for people with average hearing impairment is class D amplifiers. Devices for hearing with these amplifiers work by cutting the level of the oscillation into a half. This will create better sounds so that the sounds can be heard clearly.
The hearing aids with class D amplifiers break down the sounds into some pulses. In the process of breaking down the sounds, the wild pulses are converted from loud sounds and narrow pulses are converted from soft sounds. When the pulses are sent to the aids, they will be on.
Furthermore, there are two important benefits offered by hearing aids with class D amplifiers. The first benefit is better lifetime of the battery. Another benefit is less distortion of sounds. Compared to other classes of amplifiers in hearing aids, devices for hearing with class D amplifiers have smaller amplifiers. This will make the sounds that are resulted better.
