Resumen Noise and vibration measurements were carried out on 4 tankers, and the results expressed in the form of a total acoustic environment by using the combined NVR - noise and vibration rating as defined by Janssen (noise levels generally decrease and vibration levels increase the more remote the engine room; in tankers with no separate control room available to the engineers, the latter in most cases are exposed to noise levels exceeding 85dB). Simultaneously, 24h urinary 17-ketosteroid levels and urinary volumes were determined among ships officers, and their subjective response to noise, vibration and life on board obtained by interview. The NVR ranking of the 4 tankers tied in very well with the objective physiological response (17-ketosteroid changes) and the subjective assessment of overall comfort, but not with urinary volumes. It appears that the stressful effect of the ship's environment is somewhat alleviated by the long leave periods.
