ASHRAE Hawaii Duct System Acoustics
Duct System Acoustics
Patric Brooks, PE
Senior Project Manager for SMACNA
Wednesday, November 30th
12:00 pm - 1:00 pm HST
This presentation covers the fundamentals of calculating duct system acoustics. The designer will learn what noise is, how to mathematically combine noise levels, and how to control noise in duct systems. Frequency, amplitude, and how people perceive noise are important concepts that are also covered. The designer will also learn the difference between sound power and sound pressure and how to convert sound power levels to sound pressure. The range of hearing and the problems with low frequency noise vs. high frequency noise are discussed. Natural attenuation of duct elements and how to determine it will be reviewed. How to solve acoustic problems using distance, silencers, and duct insertion losses are examined as well as how noise criteria (NC) levels are used.
