Data are presented on changes of pitch with intensity for 18 ears, for frequencies from 125 cps to 8000 cps and for intensities up to a loudness level of approx. 100 db. There are wide individual differences, but most observers show changes of less than 2% of pitch with intensity. In general, as intensity is increased pitch falls at low frequencies and rises at high frequencies. Two different methods of measuring pitch-intensity changes showed no significant difference.
