Two interrelated and unsolved problems commonly experienced by many people with hearing aids are the inability to understand softly-spoken speech and the inability to wear hearing aids in high environmental noise levels. As one possible solution to these problems, the Etymotic Research K-Amp circuit (Killion Amplifier) has become available from several hearing aid manufacturers. Anecdotal comments from many highly enthusiastic hearing aid dispensers reveal that the K-Amp circuit has performed well for many people who are especially bothered by high levels of environmental noise. In fact, the K-Amp appears to have performed better in some of these situations than noise reduction circuits. This brief report attempts to address how the K-Amp circuit successfully handles high noise levels while also benefitting people with hearing impairments in quiet listening environments.
