Abstract: | Allowable sound pressure levels for industrial, commercial and residential sources of noise are typically governed by state and/or local noise regulations. This paper presents a six-step methodology which was successfully applied by a supermarket in Massachusetts to secure state permission to build and operate a new 52,000 square foot store. This multiple step process included baseline noise monitoring, obtaining reference sound levels of the proposed rooftop refrigeration equipment, predicting future sound levels, and recommending soundlevel mitigation techniques. Post-construction monitoring at the store verified that actual worst-case sound levels agreed with predicted values. |
