Lj. Kanis et E. Deboer, COMPARING FREQUENCY-DOMAIN WITH TIME-DOMAIN SOLUTIONS FOR A LOCALLY ACTIVE NONLINEAR MODEL OF THE COCHLEA, The Journal of the Acoustical Society of America, 100(4), 1996, pp. 2543-2546
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.
