Effects of noise and vibration on choice reaction time task and paired associates learning task

抄録

Experiments on the individual and combined effects of noise and vibration of moderate intensity were conducted with choice reaction time (CRT) task and paired associates learning (PAL) task. The experiments related to continuous noise (64 and 74 dB (A)), intermittent noise (74 dB (A), peak az) and continuous vibration (vertical whole-body sinusoidal in 5 Hz at 76 dB (re 10^-5 m/s²)). Deterioration of performance in CRT were observed in all conditions of noise alone and vibration as compared with the control (43 dB (A) ambient noise and no vibration). As regards PAL, continuous noise produced promotion of performance, but intermittent noise and vibration alone led to deterioration of performance. The noise combined with vibration demonstrated three types of effects.
