Abstract

Low‐frequency, wind‐generated ambient noise source levels are important input parameters for newly developed ambient noise prediction models such as DUNES. However, there has been a significant variation among recently reported source levels. An analysis is made of these values. Although the actual noise measurements, the assumed source model, and a small angle approximation are similar for all papers, differences arise due to additional geometrical factors or a further approximation to shift the source level to the surface. A standard source level definition and evaluation method are proposed. Standard values of low‐frequency, wind‐generated source levels are presented based on this strategy.
