To determine the combined effects of noise and vibration on mental performance as a function of time of day, subjects were randomly exposed to each of the following conditions stress 5 Hz vibration, 110 dB noise at 6 AM no stress no vibration - 85 dB noise at 6 AM stress at 3 PM and no stress at 3 PM. Subjects performance on a mental arithmetic task was measured during each of these exposures on consecutive days. The average exposure time was approximately 20 minutes. The results are discussed in the context of arousal theory. Author
