Abstract

This paper provides calculations of outdoor sound pressure levels (SPLs) at dwellings for 10 wind turbine models, to support Health Canada's Community Noise and Health Study. Manufacturer supplied and measured wind turbine sound power levels were used to calculate outdoor SPL at 1238 dwellings using ISO [(1996). ISO 9613-2-Acoustics] and a Swedish noise propagation method. Both methods yielded statistically equivalent results. The A- and C-weighted results were highly correlated over the 1238 dwellings (Pearson's linear correlation coefficient r > 0.8). Calculated wind turbine SPLs were compared to ambient SPLs from other sources, estimated using guidance documents from the United States and Alberta, Canada.

摘要

本文提供了10种风力涡轮机型号在住宅处的室外声压级（SPL）计算结果，以支持加拿大卫生部的社区噪声与健康研究。利用制造商提供的和实测的风力涡轮机声功率级，采用ISO标准（ISO 9613-2-声学，1996年）和一种瑞典噪声传播方法，计算了1238处住宅的室外声压级。两种方法得出的统计结果相当。在这1238处住宅中，A加权和C加权结果高度相关（皮尔逊线性相关系数r > 0.8）。将计算得出的风力涡轮机声压级与来自其他来源的环境声压级进行了比较，后者是根据美国和加拿大艾伯塔省的指导文件估算得出的。
