A noise source can be very complex in nature. In noise control engineering an essential first step is to identify the strongest contributing noise sources. There are many tools available for predicting noise levels in industrial workrooms. These comprise simple theoretical formulae or empirical models as well as more complex methods of image or ray-tracing approaches. These more complex methods, such as the ray-tracing approaches, are proven prediction methods, but they involve considerable calculation times. Simple formulae and empirical models involve reduced computation times, at the cost of reduced performance.

Abstract


A noise source can be very complex in nature. In noise control engineering an essential first step is to identify the strongest contributing noise sources. There are many tools available for predicting noise levels in industrial workrooms. These comprise simple theoretical formulae or empirical models as well as more complex methods of image or ray-tracing approaches. These more complex methods, such as the ray-tracing approaches, are proven prediction methods, but they involve considerable calculation times. Simple formulae and empirical models involve reduced computation times, at the cost of reduced performance.
