Digital vs. Analogue Hearing Aids

From an engineering point of view, digital processing is much more stable than analogue processing. It offers better performance and is easy to update and revise. Also, from an end user's viewpoint, digital technology performs better, occupies less space and is more reliable. Comparing CDs to vinyl LPs is an obvious example of this.

Is digital processing really necessary, or is it an expensive and complicated way of doing things?

That depends. The bottom line with digital technology is its considerable potential. Digital technology allows us to make better hearing aids. They offer the possibility of new features, that are impossible to implement in the design of a conventional analogue hearing aid. To consider what features might be offered, we need to summarize a few of the expectations from the literature:

1. programmability

2. greater precision in fitting

3. control of acoustic feedback

4. noise reduction

5. automatic control of signal levels

6. self-adaptive adjustments to changing acoustic environments

7. self-monitoring capabilities

8. compensation for recruitment

9. management of masking
