The most common symptom of hearing loss is a reduction in the clarity of speech at conversation levels that are otherwise normal in loudness. This happens because hearing loss rarely affects all pitches equally. Early hearing loss may make only the soft high tones inaudible, but because these frequencies contain the most important information for understanding words, the result is a frustrating perception of mumbled speech that is loud enough to hear but not clear enough to understand.

Current hearing aid technology is able to resolve this problem by amplifying only the parts of the signal which are missing. Sounds which can be adequately heard, or are perhaps even loud without hearing aids, are not amplified by the hearing aids. Because hearing aid microchips automatically adjust several million times every second, they can be tuned to make soft high pitches audible without amplifying the louder, but less important, lower pitched sounds of speech.

This selective amplification restores a fuller range of sounds to the language areas of the brain. Increased information reduces the time and effort required by the brain to fill in the gaps in the speech signal caused by hearing loss. Listening skills improve as the wearer learns to recognize the new sounds and their meaning. The result is less guessing at what has been said and more accurate detection of words leading to better understanding and clearer perception of speech.
