Diana Deutsch, a psychology professor at the University of California, has studied how left and right-handed people hear sound differently. In this online experiment, a right-handed listener would expect to hear most of the higher-pitched tones in the right ear, even though both channels are exactly the same. Try it, then flip your headphones around and see if the higher pitches switch sides. Iif you’re left-handed, you’ll probably hear the higher notes on the left. Deutsch suggests, since most people are right-handed, this is why more high-pitched instruments are on the right side of the orchestra.
