Identifying Localized Noise Sources During Industrial Vehicle Passbys

Abstract

Commercial truck pass-by noise is comprised of multiple noise sources that all contribute the whole of the vehicle pass-by noise, including engine, exhaust, tires and trailer-related sources. In order to determine appropriate noise mitigation strategies, it is important to understand how each localized noise source contributes to the whole of the vehicle pass-by noise emission. It is also important to know where these noise sources are located on the vehicle in question should noise mitigation be investigated.Identifying and quantifying the discrete noise sources on a vehicle pass-by can be difficult due to the transient nature of some sources. To locate and quantify these noise sources the Norsonic Nor848, an acoustic camera capable of mapping the spatial distribution of sound, was used to measure several different truck pass-by events. Using the acoustic camera, we were able to observe several loaded and un-loaded commercial trucks passing over flat and uneven road surfaces to determine the location and contribution of each localized noise source. This paper will discuss our measurement processes, findings, and conclusions of our study.
