Equipment Sound Rating
notes
Formal standards are written by industry organizations to promote uniformity
of data between different manufacturers. Air-Conditioning & Refrigeration
Institute (ARI), the Air Movement and Control Association International (AMCA),
and the American Society of Heating, Refrigerating, and Air-Conditioning
Engineers (ASHRAE) are three such organizations.
However, methods for predicting sound data may still vary from manufacturer
to manufacturer, hampering comparisons of similar equipment. Done properly,
collecting accurate sound data for an entire line of products is an expensive and
time-consuming endeavor. A single product line may consist of many models,
and each model may come in a range of sizes with various options that alter the
sound generated by the equipment.
