Are you becoming hard of hearing and wondering whether a digital hearing aid is for you? The fact that there are so many people affected by hearing loss has given rise to new research into hearing loss. In the last decade, there has been a sharp increase in the range of hearing aids on the market, and the state-of-the art digital hearing aid improves the hearing capacity of the hearing impaired person. A digital hearing aid is a device that receives sound and breaks the sound waves into minute units and amplifies the sound. The main difference between the old analog hearing aid and digital hearing aid is that while analog hearing aid magnifies the sound to amplify sounds, digital hearing aid breaks the sounds waves and amplifies it. While in-the-ear hearing aids are fixed in the outer ear, the behind-the-ear hearing aids fit behind the ear connecting to a plastic ear mold that fits inside the outer ear. Canal aids fit into the ear canal. Body aids are for those who are affected by profound hearing loss and it is attached to the pocket or belt that is connected to the ear by wire. How Do Digital hearing aids Work?Digital hearing aids convert the analog waveform into a string of numbers for processing.
It receives the continuous sound wave and splits it into very small discrete bits of data. This process is called ‘digitizing the sound waves’. Most of the digital hearing aids follow this process to produce superior sound quality. The latest digital hearing aids have sophisticated technology to amplify even the softest sounds. While processing the sound wave, this modern equipment filters the unwanted noises.
