项目摘要

Noise is a major contributor to health problems in cities, second only to air quality in terms of harms (European Quality of Life Study, 2020). The World Health Organisation conservatively estimated the disability-adjusted life-years lost from environmental noise in western European countries to include: 61,000 years for heart disease; 903,000 years for sleep disturbance, and 654,000 years for annoyance. In the West, around 87% of time is spent indoors, so buildings must insulate occupants from noise to improve health and well-being. The climate emergency is forcing the construction industry to change. In future, many more building elements will be prefabricated in factories using more sustainable materials such as Cross Laminated Timber (CLT). Currently, there are no robust methods to predict acoustic performance, which is holding back the development of CLT partitions. Instead, the acoustic performance of CLT is measured on a case-by-case basis to ensure products satisfy legislative requirements. Such tests are large-scale and involve expensive infrastructure, which can be prohibitive, especially for small and medium-sized enterprises developing newproducts. Furthermore, the SARS-CoV-2 pandemic has caused a reduction or redirection of research and development budgets, meaning that small start-ups face major hurdles to fund innovation. The overarching goal of SIMPLE is to unlock the potential of CLT products for sound insulation by creating a generic approach to design using hybrid methods that combine prediction and measurement. This new approach will reduce development costs, by reducing the extent of acoustic testing, and so improve economic efficiency for manufacturers and the construction industry. Thus, in the long term, SIMPLE will facilitate lower noise levels indoors, improving health and well-being for many people.

就危害而言，噪音是城市健康问题的主要因素，仅次于空气质量(欧洲生活质量研究，2020)。世界卫生组织保守估计，西欧国家因环境噪音而损失的残疾调整寿命年包括：心脏病6.1万岁；睡眠障碍90.3万岁；烦扰65.4万岁。在西方，大约87%的时间是在室内度过的，因此建筑物必须将居住者与噪音隔绝，以改善健康和福祉。气候紧急状态正迫使建筑业做出改变。未来，更多的建筑元素将在工厂中使用更可持续的材料预制，如交叉叠层木材(CLT)。目前，没有稳健的方法来预测声学性能，这阻碍了CLT分区的发展。相反，CLT的声学性能是在个案的基础上进行测量的，以确保产品满足法律要求。这样的测试规模很大，涉及昂贵的基础设施，这可能是令人望而却步的，特别是对于开发新产品的中小型企业。此外，SARS-CoV-2疫情导致研发预算减少或重新定向，这意味着小型初创企业在为创新提供资金方面面临重大障碍。SIMPLE的首要目标是通过创建一种使用预测和测量相结合的混合方法进行设计的通用方法，来释放CLT产品在隔音方面的潜力。这种新方法将通过减少声学测试的范围来降低开发成本，从而提高制造商和建筑业的经济效益。因此，从长远来看，SIMPLE将有助于降低室内噪音水平，改善许多人的健康和福祉。
