SOME PRIMARY AUDITORY ABILITIES IN PITCH AND LOUDNESS

Ninety-two young men with normal auditory acuity were given 18 separate auditory tests involving frequency, intensity, and contact detection. Test data were intercorrelated and factor analyzed by a centroid technique. The following factors were identified pitch-memory, pitch-modulation, loudness masking in noise, complex auditory determination and loudness, discrimination at 1,000 cps, and masking for 1,000 cps in wide-band noise. The two pitch factors were correlated more closely than were the loudness or masking factors. Evidently, the loudness domain was not covered sufficiently by the tests used to provide a further description of loudness discrimination. Another matrix of loudness tests alone is envisaged.
