SSA Acoustics completed a thorough noise assessment of the
space developing a noise map to describe the sound within the space. From these
test results a 3-dimensional noise model was created to provide a virtual test
environment. Within this test
environment we were able to predict the performance of various mitigation
measures, eliminating guess work.
A phased design and installation approach was recommended to
address the most significant noise sources first. We engineered one solution to reduce sound
transmission from the large diameter piping utilizing a mass-air-mass barrier
pipe wrap; this assembly was designed specifically for this application and reduced
the overall noise level by 6-8 decibels, which is a 70% noise reduction.
