Sound Quality Evaluation of Power Seat Adjusters

摘要

The present study utilized the DoE method to derive psychophysical functions for a selection of parameters strongly related to the noise annoyance of power seat adjusters. A listening experiment was performed based on the experimental variations of three parameters (f_(mod, m, △f_c(t)). As opposed to a full-factorial design that would have resulted in a total of 125 stimuli, the DoE method required to prepare only 15 noises for the auditory assessment. Subspace diagrams were derived from mean annoyance ratings according to the DoE standards which allowed for an estimation of the underlying psychophysical functions.
