HEARING AID TECHNOLOGY
Programmable hearing aids are custom programmed using a computer with special software. The information in an audiogram is entered into the computer, and the hearing aids are then adjusted by computer to give the best possible hearing improvement. They can be reprogrammed or fine-tuned at any time.
