Abstract

An auditory-input/keypad-output system was evaluated for use as a performance test system that would be independent of artifactual vibrational decrement. Six young Navy volunteers were administered a non-cognitive Auditory Response Task Before, During, and After whole-body sinusoidal vibration. Two were tested at each of three vibration conditions (8 Hz/0.21 gzrms, 16 Hz/0.43 gzrms, and 32 Hz/0.85 gzrms). Results showed no direct decrement due to vibration, but a moderately significant subjects-within-conditions by frequency interaction. This interaction, paired with subjective measures taken during experimentation, pointed to a deficit in the keypad output system. It was concluded that the system was not satisfactory for future experimentation and recommended that a modified input system be developed. It is noted that purely cognitive effects of vibration have not been identified in the body of previous research.
