Cerami & Associates provided acoustical consultancy for the Park Avenue Synagogue’s rooftop liquid chiller. The chiller, located directly across from the bedroom of residents living next to the synagogue, created a disturbance as it cycled on and off during the evening hours. To make things worse, the synagogue’s chiller was located on top of steel litter on the roof, which amplifies the noise.
Cerami provided extensive site surveys on both the roof of the synagogue and the adjacent tenant space. These site surveys were used to determine whether the noise violated New York City building noise codes and to also ensure the recommendation of appropriate acoustical applications. We made specifications for acoustical lagging for each of the chiller’s compressors and the construction of an acoustical noise barrier. The noise barrier was specified to be constructed with fiberglass, mineral rock and plywood to aid in the mitigation of sound transmission from the synagogue’s chiller to the adjacent residential buildings.
