What can you tell me about digital hearing aids?

There are many digital hearing instruments available, including modern designs that are discreet and wireless, easy to operate, and fully automatic. Most of these hearing aids analyze sounds, determine if the sound is speech versus noise and then convert this information to numbers which are analyzed and manipulated by a set of rules or algorithms that are programmed into a chip that controls the hearing aid amplification. As a result, digital hearing aids have less distortion than is generally found in analog hearing aids. These devices are extremely flexible and can be fine-tuned in many different ways via a computer.
