A digital hearing aid takes signals from the microphone and converts them into a code. The code is then manipulated by a tiny computer in the hearing aid to enable digital hearing aid to be set to an individual’s hearing needs. A digital hearing aid is a device which gets sound and then digitizes it before the amplification. To digitize means to break the sound into small units. A hearing aid which is analogue simply makes the sound higher to intensify the sound. And just like the analogue hearing aids, digital hearing aids as well come in different prices and a variety of capabilities. Digital hearing aids can be different, but the most sophisticated ones have the ability to decide what is wanted and what is unwanted. So it can discern between soft, wanted sounds and loud, unwanted sounds. A digital hearing aid can be programmed to adjust itself, so that the hearing can always be just right, there are no volume settings because everything is done digitally. What is also great with this type of hearing aid is that technologists can make a digital hearing aid customized to the needs of an individual. Because not everyone has the same hearing disabilities. Some hear better some worse, and therefore this is an excellent way to get exactly what you need from a hearing aid.
