Digital Hearing Aids
Digital Hearing aid, which means incoming sound is converted into a series of numbers which are then processed using mathematical equations. Very complex manipulation of sound can be done by digital processing, for example, to separate speech stimuli from the overall noise floor present.
The digital technology within hearing aids allows sounds to be divided into separate frequency regions, or bands, and amplify each region selectively, depending on the hearing aid user’s hearing loss. It also enables different amounts of amplification for soft, moderate, and loud sounds, so that soft sounds are audible, but loud sounds are not uncomfortable or over amplified. Digital signal processing allows a more natural sound quality.
Digital hearing aids are programmable, the hearing aid settings can be precisely fine-tuned, and special features can be adjusted for each patient or user by the Audiologist.
Some of the key feature which makes it more powerful in terms of usage and performance are:
· Noise Reduction
· Feedback Management
· Wind Noise Reduction
· Data Logging/Learning
· Bluetooth Interface or Connectivity
· Online Programming or Fine tuning.
