A Psychoacoustical Evaluation of the Frequency Influence on the Human Binaural-Beat Perception
When two tones of slightly different frequencies are presented to each ear separately, binaural beats might be heard. Although this is an old topic, there is a renewed interest in such beats due to novel applications indicated by recent electrophysiological and psychological studies. This paper reports psychoacoustical experiments conducted to study the human binaural-beat sensitivity. We observed that it decreases almost linearly with the stimulus frequency, being virtually zero for 1400 Hz. Unlike previous works, the obtained data were analyzed using signal detection theory, so that the results are theoretically bias-free and independent of the psychophysical procedure.
