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.

噪声是城市健康问题的主要贡献者，仅在危害方面仅次于空气质量（欧洲生活质量研究，2020年）。世界卫生组织保守地估计，西欧国家的环境噪音损失的残疾调节年度包括：61,000年的心脏病；睡眠障碍的903,000年，烦恼654,000年。在西方，大约87％的时间在室内花费，因此建筑物必须使居民免于噪音，以改善健康和福祉。气候紧急情况迫使建筑业发生变化。将来，使用更可持续的材料（例如跨层压木材（CLT））将更多的建筑要素预制在工厂中。当前，没有可预测声学性能的强大方法，这阻碍了CLT分区的开发。取而代之的是，CLT的声学性能是根据具体情况衡量的，以确保产品满足立法要求。这样的测试是大规模的，并且涉及昂贵的基础设施，这可能是过于艰难的，尤其是对于开发新产品的中小型企业而言。此外，SARS-COV-2大流行导致了研究和开发预算的减少或重定向，这意味着小型初创企业面临着重大障碍以资助创新。简单的总体目的是通过使用结合预测和测量的混合方法来创建一种通用的设计方法来释放CLT产品的潜力来进行声音绝缘。这种新方法将通过减少声学测试的程度来降低发展成本，从而提高制造商和建筑行业的经济效率。因此，从长远来看，简单将促进室内较低的噪音水平，从而改善许多人的健康和福祉。
