Post-installation measurements of mechanical system noise and vibration in order to arrive at an engineered noise-control solution for newly installed air handlers and transformers, along with evaluation of performance of industrial-scale silencers.
Vibration Isolation
The Talisman Centre, Multi-Sports Complex
Madison Avenue Radiology Center, 1820 Madison
Atop a mixed-use building, the rooftop cooling systems, connected to a ground-level magnetic resonance imaging (MRI) installation, caused complaints from the residents within a penthouse condominium. Noise and vibration measurements were made to compare levels to the provisions of Local Law 113 Noise Code along with recommendations to mitigate the problematic levels.
