As
many of you know, we have been evaluating and fitting the fully
digital hearing aids. Digital hearing aids are now available in all
styles, including the small completely in the canal style. The
response to this new technology has been excellent.
Digital
hearing aids use a computer processor to make more than a
million calculations per second to process and control
incoming sound. The microprocessor actually measures the pitch and
loudness of the sounds and responds automatically. The advantages
we have seen include:
Easier to use because volume control is fully
automatic;
Better hearing for soft sounds because the
aids can be programmed for greater amplification of soft sounds;
Greater comfort for loud sounds because the
aids can be programmed to automatically reduce amplification as
sounds get louder;
More exact fit to a wide range of hearing
loss patterns because of the microprocessor's tremendous
flexibility;
