What are Digital Hearing Aids?
The term digital is used for most of today's current technology, from televisions to cell phones. Hearing aids today are also digital, meaning incoming sound is converted into a series of numbers, which is then processed using mathematical equations. Digital processing enables very complex manipulation of sound, for example, to separate speech from noise.
The digital technology within hearing aids also allows to separate sound into different frequency regions and amplify each region selectively, depending on the hearing aid wearer’s hearing loss. The processing within hearing aids also enables different amounts of amplification for soft, moderate, and loud sounds, so sounds are audible, but loud sounds are not uncomfortable or over amplified. And, digital processing enables a natural sound quality with minimal distortion, resulting in excellent sound quality.
Digital hearing aids are programmable, meaning the hearing aid settings can be precisely fine-tuned and special features can be adjusted for each wearer by a hearing aid professional, using special hearing aid software on a computer. Hearing aids are programmed and customized for both the hearing loss and the preferences of the person who wears them.
