Even with all its sophistication, digital technology can’t know the words you need to hear or magically eliminate the noise you don’t want to hear.
That magic only occurs in your brain. With the right kind of input from both ears, it selects and ‘concentrates’ on the desired sounds. A million times more powerfully than any man-made processor.
When a hearing loss alters that input, digital technology can help improve understanding by selectively controlling certain characteristics of the signal.
Your willingness to relearn the necessary listening skills as you adapt to a world of amplified sound is the single most important factor in your success.
