Mathematical models of human auditory systems can contribute tremendously to the understanding of experimental hearing data and sound signal processing. A success story was MP3, a remarkable sound compression tool that employed empirical models of hearing threshold curves of human sound perception to significantly reduce the bit width of digital sounds [ 21,  134]. It has been routinely used for downloading and playing digital music.
