Abstract

In a previous study of the beating complex by the writer two electrically driven tuning forks having frequencies of 256 d.v. and 244 d.v. respectively were used as the source of the tones. The intensities of the two tones could be valued independently from maximum to minimum by means of rheostats. The sound was conducted to the observer in a sound proof room by means of rubber tubes. When the two primary tones had equal intensities two beating intertones were heard. The pitch of one was near the upper primary while the pitch of the other was near the lower primary.
