HUMAN HEARING AND SPEECH DURING WHOLE-BODY VIBRATION

Binaural thresholds for four tones (500, 1000, 2000, and 4000 cycles per second) and tape recordings of spoken messages were obtained from eight subjects under various conditions of vertical sinusoidal vibration. The vibration frequencies ranged from 1 to 27 cps and were presented at four subjective...

description	Binaural thresholds for four tones (500, 1000, 2000, and 4000 cycles per second) and tape recordings of spoken messages were obtained from eight subjects under various conditions of vertical sinusoidal vibration. The vibration frequencies ranged from 1 to 27 cps and were presented at four subjective reaction levels. These data were systematically compared to control data obtained when no vibration was present. Hearing thresholds were significantly affected by vibration, but the effects were variable from subject to subject and from tone to tone. Rated judgments of change in intelligibility and speech ''pattern'' were inconclusive because of a lack of spread in the ratings. Report on Research On Low Frequency Vibration Effects On Human Performance.
