Why State-of-the-Art Technology
Until recently, all electronic devices such as televisions, stereo systems and hearing aids have employed analog technology. In an analog world, sound waves are collected, turned into electronic signals and then made audible again using an amplifier and loudspeaker. This technology provides a realistic depiction of the sounds that were recorded but it does have its limitations. Just think about the hissing and popping
of a record versus the clean, clear sound of a compact disc.

With the widespread use of computer technology, digital signal processing has begun to take over nearly all analog applications. Instead of sound waves being turned into electromagnetic energy, they are now scanned by computer chips, measured and then split into discrete components. Finally, these components are turned into a language called binary code. This code can be manipulated to greatly enhance sound. What was originally recorded can then be reproduced without distortion or artifact.

In the case of hearing aids, digital technology makes it possible to manipulate sound frequencies to more closely match an individual’s hearing loss. Digital hearing instruments can amplify a wider dynamic range of sounds and may contain a variety of auditory lenses and filters to improve hearing in the most difficult
of settings.

Patients who wear digital hearing instruments, experience significantly greater satisfaction than those wearing analog models. They also appreciate the longer functional lifespan the technology brings since these instruments can be programmed over and over again, as well as the excellent warranty protection that comes with digital technology.
