Abstract
Previous papers [e.g., Kanis and de Beer, J. Acoust. Sec. Am. 94, 3199 -3206 (1993); 96, 2156-2165 (1994)] have described and applied an appr oximation method, called the quasilinear method, to solve nonlinear lo cally active cochlea models in the frequency domain. This method consi sts of treating higher-order distortion components as perturbations. T his letter compares results obtained with the quasilinear method with results computed in the time domain. The time-domain method described by Diependaal et al. [J. Acoust. Sec. Am. 82, 1655-1666 (1987)] was us ed. The comparison for single-tone as well as for two-tone stimulation was performed. In most cases the match between the two solutions is e xcellent. (C) 1996 Acoustical Society of America.
