1. A computer-implemented method for programming a hearing aid device, the method comprising: collecting a plurality of audiograms from a plurality of individuals, an audiogram being a collection of hearing thresholds at various frequencies for a particular individual from said plurality of individuals; dividing the plurality of audiograms from the plurality of individuals into one or more sets of audiograms; creating by a processing device a representative audiogram for each set of said one or more sets of audiograms, the representative audiogram representing multiple individuals, the representative audiogram calculated as an overall mean of audiograms in the set of said one or more sets of audiograms; computing a hearing enhancement fitting based on the representative audiogram; and programming a hearing aid device with one or more hearing enhancement fittings computed based on the representative audiogram.
