The spatial buildup of nonlinear compression in the cochlea by Kostas Kondylidis, Kostas Kondylidis, Anna Vavakou, Anna Vavakou, Marcel van der Heijden

“…Previous work by our group suggested that compression does not occur locally, but is realized by a cascade of weakly nonlinear elements along the cochlear partition. The resulting progressive accumulation of nonlinearity was termed the spatial buildup of compression. …”
