Provided measurements and analysis to document the extent to which noise within 4th floor office spaces is compromised by a poorly vibration isolated chiller in a 5th floor mechanical room. Provided recommendations for design improvements.
Comprehensive design services including architectural acoustics; and mechanical noise control and vibration isolation.
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.
Comprehensive design services including specification of mechanical noise control for two gas turbines; 2000-cooling ton chillers; and operators’ room
Provided LEED credit design review for acoustics of administration/control/maintenance building.
Residential Sound Insulation Program. Measured sound transmission of aircraft noise within approximately 160 single family dwellings.
Recommendations to Papakura District Council for a program of residential sound insulation at a general aviation airport with historic 1950s vintage “warbird” jet fighters.
Analysis and reporting of Noise Isolation Class (NIC) of doors and partitions to assess contractual compliance.
