Digital Hearing AIDS

Fully digital hearing aids process sound mathematically. In place of electronic components, digital hearing aids contain hundreds of tiny electrical parts which are micro-manufactured into a signal silicon chip. The computer programmed chip applies continuous digital processing to incoming sound. Here’s how these digital hearing aids work:

Five Step Guide to
How digital Hearing Aids Work

1

The hearing aid microphone turns sound into an electrical signal.

2

A filter removes inaudible frequencies.

3

The electrical signal goes to the analog-to-digital converter, which changes it to a digital signal to be manipulated by the hearing aid’s computer (DSP chip)

4

The chip is programmed to perform many operations (noise reduction, filtering feedback cancellation, etc.) depending on the algorithm used.

5

The digital signal is converted back into audible sound for the patient to hear. These functions are performed instantly and continually.

User Benefits For Digital Hearing Aids

  • Availability of Automatic Signal Processing circuits which are not available with non-programmable instruments
  • Multiple circuit options within a single instrument which achieve different sound qualities.
  • Automatically achieves more volume for the soft, high frequency sounds and less volume for the more intense, low frequency sounds.
  • Capable of retaining the patients complete audiometric file and preferred listening programme for various environments.
  • Ability to readjust your prescription should your hearing loss change.

 

6 IMPORTANT QUESTIONS TO ASK ABOUT DIGITAL HEARING INSTRUMENTS

1 How many channels does it have? How many do I need?

2 What type of Automatic Signal Processing compression does it use and what type would best suit my current lifestyle?

3 Does it offer directional microphones for hearing in noise?

4 Does it have wireless capability? Do my listening situations indicate I would benefit from hearing aids with wireless compatibility?

5 How many memories does it have? How many various listenings situations do I encounter?

6 Does it come with a remote control? Do I need a remote control?
