Listeners stream interleaved tones by pitch rather than by ear of delivery

Evidence

In a further experiment, Deutsch (1975) played an ascending and descending C major scale simultaneously with alternate notes being switched between the two ears as shown in the lower part of Figure 5.13. The most commonly perceived response is also shown in the figure. Once again, the high notes tend to be heard in the right ear and the low notes in the left ear, resulting in a snippet of a C major scale being heard in each ear. Such effects are known as “grouping” or “streaming,” and by way of explanation, Deutsch invokes some of the grouping principles of the Gestalt school of psychology known as “good continuation,” “proximity” and “similarity.” — David M. Howard, Jamie Angus, Acoustics and Psychoacoustics, 1620
