INDUSTRIAL NOISE CONTROL

Food Processing Plant, Bordentown, New Jersey

Food Processing Plant, Bordentown, New Jersey · Noise was overlooked in the design of a new ammonia refrigeration system for this food processing plant. When operational, the nearest residents strongly complained of noise from the system. The noise emanated primarily from a vertical array of air-cooled heat exchangers. Based on Ostergaard Acoustical Associates analysis and design, a 45-foot tall noise control barrier was installed. The barrier reduced the noise level by 15 dB, brought the plant into compliance with the New Jersey Noise Code, and allowed plant operations around-the-clock.
