dc.description.abstract | An efficient method for measuring stimulus-frequency otoacoustic emissions (SFOAEs) was developed incorporating (1) stimulus with swept frequency or level and (2) the digital heterodyne analysis. SFOAEs were measured for 550-1450 Hz and stimulus levels of 32-62 dB sound pressure level in eight normal human adults. The mean level, number of peaks, frequency spacing between peaks, phase change, and energy-weighted group delays of SFOAEs were determined. Salient features of the human SFOAEs were stimulated with an active cochlear model containing spatially low-pass filtered irregularity in the impedance, An objective fitting procedure yielded an optimal set of model parameters where, with decreasing stimulus level, the amount of cochlear amplification and the base amplitude of the irregularity increased while the spatial low-pass cutoff and the slope of the spatial low-pass filter decreased. The characteristics of the human cochlea were inferred with the model. In the model, an SFOAE consisted of a long-delay component originating from irregularity in a traveling-wave peak region and a short-delay component originating from irregularity in regions remote from the peak. The results of this study should be useful both for understanding cochlear function and for developing a clinical method of assessing cochlear status. (c) 2008 Acoustical Society of America. | - |

The experiments were conducted while Y.-S.C. was visiting the University of Connecticut Health Center supported by Brain Korea 21 Project, the School of Information Technology, KAIST, in 2002–2003. Y.-S.C. and S.-Y.L. have been supported partly by the Brain Neuroinformatics Research Program sponsored by Korean MOST and MOCIE from 2001. We thank Dr. Gerhard Hill for assistance in making measurements using the conventional method, Dr. S. Puria for providing numerical middle-ear data, Dr. M. Ruggero and Dr. A. Temchin for providing numerical cochlearpartition data. We also thank Dr. J. Siegel, Dr. C. Shera, and Dr. M. Ruggero for helpful discussions on topics of this study. | en |
