ABSTRACT:
A "loudness balance" procedure is used to determine the amount of dynamic range for syllabic compression loss in an individual's cochlea. In particular, an individual is asked to adjust a set of tone volumes, which are played to them, until the tone volumes sound equally loud. Based on the adjustments performed by the individual, a compression ratio is determined for that individual over at least one frequency band. The determined compression ratio is then subsequently used by a telecommunications system to provide an individual-specific sound enhancement in a telephone call. As a result, the individual-specific sound enhancement particularly compensates for an amount of hearing loss unique to that individual.
