Abstract

This study was designed to evaluate noise exposure of motorcyclists at work. Open and full face safety helmets were compared and the effects of helmet design and the contribution of radio intercoms investigated. Special measuring equipment is described and hearing protection discussed. Previous studies concentrated mainly on the attenuation of noise by safety helmets, and were made under conditions untypical of day-to-day motorcycling. During town driving the sample equivalent continuous noise level (s.leq) ranged from 63 to 90 dB(A), the intercom giving the highest peak levels. On the open road s.leq was up to 105 dB(A); exposure to this level for only 15 min would exceed the present recommended maximum of 90 dB(A) for an 8 h working day.

摘要

本研究旨在评估摩托车骑手工作时的噪声暴露情况。对开放式和全脸式安全头盔进行了比较，并研究了头盔设计的影响以及无线电对讲机的作用。介绍了专用测量设备并讨论了听力保护问题。以往的研究主要集中在安全头盔对噪声的衰减上，且是在非日常骑摩托车的典型条件下进行的。在城镇行驶时，样本等效连续噪声级（s.leq）范围为63至90分贝（A），对讲机产生的峰值水平最高。在开阔道路上，s.leq高达105分贝（A）；仅暴露于该水平15分钟就会超过目前建议的8小时工作日90分贝（A）的最大限值。
