摘要

A simple acoustic radiation computer model based on the ISO 9613 parts 1 and 2 standards is applied with enhancements to address the effects of the large source size of industrial equipment. Large equipment modeled as a point source is discussed and how a point noise model can be adapted to accurately estimate sound from large sources. Often, industrial facility noise models ignore obvious factors, such as partial screening or partial reflections from large sound sources, directivity effects and the physical source dimensions as well. This paper addresses these typically ignored effects that are uniquely important to large industrial equipment by exercising the SPM9613~(TM) computer model to estimate the inaccuracy of simple point source models. The paper also presents comparisons of predicted and measured sound pressure levels of a simple cycle gas turbine power generation facility using the large source model.
