It has long been known that amplification alone in a hearing aid is not enough to enable someone with hearing loss to not only hear everything clearly again, but also as naturally as possible.
The human hearing system has a distinct dynamic range within which sounds can be detected and remain comfortable. In people with impaired hearing, this dynamic range is reduced. This means that they perceive loudness differently.
The result of simple amplification is that some sounds are still too soft, stay below the hearing threshold level and therefore remain inaudible. Conversely, other signals may be amplified too much, causing loudness discomfort.
To date, with many hearing aids, while most sound signals will indeed be reproduced within the residual hearing range of someone with hearing loss, they may not be perceived correctly in relation to the person's changed dynamic range or sound natural.
A new type of audio-processor is now available and used by several manufacturers in different ways in their hearing systems to manage and control hundreds of parameters.
The ability for all of them to react quickly and accurately to different sound situations means that the very latest audio-processors allow carefully controlled, amplified sound to be more accurately reproduced than before, to keep pace with the ever-changing soundscape a person experiences.
