Excessive sound levels at events where amplified music is a central element pose a risk to hearing. Whereas noise exposure in the workplace has been recognized as a hazard for over a century, the potential harm resulting from recreational sound exposure has only become apparent in recent years. In occupational settings where sound levels are high, employers are required to implement risk-mitigation strategies to reduce sound exposure and protect employees in accordance with the hierarchy of controls. In principle, this same risk management approach can be applied to entertainment venues. In this paper we discuss how the measures stipulated in various policies and regulations aimed at protecting the hearing of audience members at entertainment venues fit within the hierarchy of controls. We compare the relative likely effectiveness of each of the measures and outline how the particular characteristics of entertainment venues impact on the practical application of these measures.
在以扩声音乐为主要元素的活动中，过高的声级会对听力造成危害。尽管一个多世纪以来，人们已经认识到工作场所的噪声暴露是一种危害，但近年来，人们才开始意识到娱乐性声音暴露所带来的潜在危害。在噪声水平较高的职业环境中，雇主需要根据控制层级来实施风险缓解策略，以减少噪声暴露并保护员工。原则上，这种风险管理方法也可以应用于娱乐场所。本文讨论了旨在保护娱乐场所观众听力的各项政策和法规中规定的措施如何适用于控制层级。我们比较了各项措施的相对有效性，并概述了娱乐场所的特定特征如何影响这些措施的实际应用。
