“…In this regard, several efforts had been made to develop computational models ͑Deng and Geisler, 1987;Goldstein, 1990;Kates, 1991;Carney, 1993;Kates, 1995;Robert and Eriksson, 1999;Zhang et al, 2001;Meddis et al, 2001;Bruce et al, 2003;Sumner et al, 2003;Tan and Carney, 2003͒ that integrate data and theories from a wide range of research in the cochlea. Describing and understanding the mechanisms behind the nonlinearities in the cochlea such as compression, two-tone rate suppression, etc., was the main focus of these modeling efforts.…”
