Influence of vehicle color on loudness judgments (L)

This experiment investigates the effect of images of differently colored sports cars on the loudness of a simultaneously perceived car sound. Still images of a sports car, colored in red, light green, blue, and dark green, were displayed to subjects during a magnitude estimation task. The sound of an accelerating sports car was used as a stimulus. Statistical analysis suggests that the color of the visual stimulus may have a small influence on loudness judgments. The observed loudness. differences are generally equivalent to a change in sound level of about 1 dB, with maximum individual differences of up to 3 dB. (c) 2008 Acoustical Society of America.
