Abstract Noise from domestic ventilation systems is currently a little understood problem in the UK. Other European countries that have a longer history of using mechanical domestic ventilation systems have introduced noise limits for these systems. Without mandatory limits for noise in UK, noise is not a factor that is often considered during the design. However, noise can be a significant constraint to the use of ventilation systems. Research is reviewed from across Europe and North America which indicates residents turn off ventilation equipment that has objectionable noise. Without adequate ventilation in modern airtight dwellings, poor air quality can have a significantly adverse effect on the health of the occupants. There is a lack of evidence in the literature and performance standards for appropriate noise metrics and values that occupants find acceptable: this research is urgently required, and the steps to realise this are outlined; interim noise limits are proposed. Causes of excessive noise are found to originate due to problems during the design, procurement, installation, commissioning and operation of ventilation systems. A suitable metric is required along with regulatory control to ensure that residents are not forced to choose between intolerable noise or inadequate air quality.

太大声是多少？来自家用机械通风系统的噪音

摘要 来自家庭通风系统的噪音目前在英国是一个鲜为人知的问题。其他使用机械家用通风系统历史较长的欧洲国家已对这些系统引入了噪声限制。在英国没有对噪音的强制性限制，噪音不是设计过程中经常考虑的因素。然而，噪音可能是通风系统使用的重要制约因素。来自欧洲和北美的研究表明，居民关闭具有令人反感的噪音的通风设备。现代密闭住宅如果没有足够的通风，糟糕的空气质量会对居住者的健康产生显着的不利影响。对于居住者认为可接受的适当噪声指标和值，文献和性能标准中缺乏证据：迫切需要进行这项研究，并概述了实现这一点的步骤；提出了临时噪声限值。发现噪音过大的原因源于通风系统的设计、采购、安装、调试和运行过程中的问题。需要一个合适的指标以及监管控制，以确保居民不会被迫在无法忍受的噪音或空气质量不足之间做出选择。通风系统的调试和运行。需要一个合适的指标以及监管控制，以确保居民不会被迫在无法忍受的噪音或空气质量不足之间做出选择。通风系统的调试和运行。需要一个合适的指标以及监管控制，以确保居民不会被迫在无法忍受的噪音或空气质量不足之间做出选择。
