Shipboard Habitability During Low Frequency Active Sonar Operations: Mood Effects

摘要

This component of the low frequency active sonar noise (LFAS) exposure researchproject evaluated the effects of sonar exposure on mood and subjective activation. Volunteer participants (n=45) exposed to sonar at 83 dB (n = 11) or 89 (113 (n = 34)) were studied. Mood and activation were adversely affected by LFAS onset, but the effects of exposure to 89 (113 were the same as those for exposure to 83 dB) even in subjects whose personality traits should make them exceptionally sensitive to the exposure. Mood and activation effects of LFAS exposure do not provide a basis for choosing between the exposure intensities considered here because these effects were the same for 83 (113) and 89 (113).
