A widely common principle of sound quality engineering is the development of objective measures determining human perception. Beside stationary sound parts, auditory events that are based on time-variant attributes have a traceable influence on human perception, particularly in the field of product sound quality. In this paper the significance and identification of the relevant sound quality parameters for power seat adjusters are investigated with a specific design of experiments (DoE). This methodology was used to advance the efficiency of subjective tests. The necessity of an efficient design is given through a relatively high number of variable parameters and, furthermore, through the demands of a qualitative experiment with limited effort for each subject in the listening tests. Instead of investigating randomly picked sounds this approach concentrates on a systematic scanning of the parameter space. With the results, this paper propose both to enhance the capabilities of subjective response tests and to ensure the essential high quality claims to subjective testing.
