The accuracy of any environmental noise impact model depends on the quality and application of its input data, typically consisting of at-source emission levels, propagation factors, and receiver characteristics. In the realm of construction noise modelling, this starts with the determination of the noise emission level for each construction activity or item of equipment. This data can be procured from a variety of sources including manufacturer data, standards and guideline documents, or proprietary measurements. This study explores how emission levels from different data sources can be utilized to assess noise impacts against project criteria, and aims to validate the reliability through real-world case studies.
