Development and validation of spreadsheet tools for noise path characterization

Machinery noise is a major issue in many industries. Some industries, like aerospace, automotive, HVAC, and heavy equipment, are well equipped to determine noise mitigation measures and design accordingly even in the early product development stages. However, noise control practice is limited in most manufacturing industries including textile, paper, metal fabrication, and food preparation. The objective of this work is to develop a simple spreadsheet tool that can be used to predict the effectiveness of common noise treatment measures. Though some basic noise control knowledge is needed, the user need not be a noise control expert. The methods and relevant theory are described. As examples, the methods have been applied to a generator set and HVAC equipment in a bakery
