HEARING AID TECHNOLOGY -

A hearing instrument contains mainly two different types of electronic circuitry.

Analogue or Conventional Analogue & Digital.

CONVENTIONAL ANALOGUE -

This type of circuity offers few automatic features and limited flexibility. Volume is adjusted mannually and it is not possible to program the hearing instrument. The circuit treats both soft and loud sounds the same, which means that both speech and background noise typically become louder.

DIGITAL -

Digital devices are the most advanced solutions on the market today. It can be programmed using a computer or trimmer controlled in economical models. A digital instrument provides the greatest flexibility for matching individual hearing requirements and filtering out unwanted sounds. The performance of these instruments can also change with listening needs for example, they can analyze surrounding sounds to maximize soft speech like sounds, while minimizing louder background noises such as traffic or wind.

DIGITAL ADVANTAGES -

Digital processing of sound ensures great sound quality and makes it possible to create hearing instruments with enhanced processing features. Some of the advantages are :

Directionality

Directional technology features advanced microphones that can identify sounds based on the direction they are coming from. Unwanted sounds coming from a certain direction can then be reduced. For example, background noises coming from behind are dampened while others sounds coming in front (such as speech ) are amplified. Directionality is scientifically proven to be the single most important means of understanding speech in noisy situations.

Feedback Cancellation

Feedback cancellation monitors for feedback squealing while the listeners is wearing the hearing instrument. Moderate feedback is than reduced or eliminated by a digital cancellation system.

Multiple Programs

Many hearing instruments can be set up with a variety of listening programs for different sound environments. Pressing a button on the aid or on a remote control allows you to instantly change programe - from quiet to noise, for example, when going outside onto a busy street.

Noise Reduction

The noise reduction processing available in some digital hearing instruments assist to discriminate between sounds that the user probably wants to hear - such as speech. Noise reduction is also useful in quiet surroundings to dampen softer, often irritating sounds such as the hum of computers, ventilating systems and household appliances.
