About digital hearing aids…

Digital hearing aids take the continuous sound wave and break it up into very small, discrete bits of information. This is called digitizing the signal and all digital hearing aids do this. The very fact that a hearing device is digital does not make it better than a comparable analog hearing aid device.

Beyond just digitizing the sound prior to amplification, there are differences in exactly how various digital hearing aid devices amplify or process sound. The more sophisticated digital hearing aids are able to amplify the softest sounds of speech while at the same time subtracting out certain types of unwanted noises.

Digital signal processing allows hearing aid designers to write computer programs, called algorithms that can be customized to each individual's hearing loss. In addition, digital hearing aids enable important features — such as directional microphone arrays, and multiple user programs to be placed into cosmetically appealing device. It is this potential that makes digital hearing devices so promising for so many hearing losses.

Selecting the type of hearing aid that is right for your hearing loss and unique listening needs requires the guidance of a professional well versed in all of variations of hearing instrument technology. Today, over 75% of all hearing aids sold are digital.
