ABD Engineering & Design worked with MWA Architects to provide full acoustical consulting for this 110-unit affordable housing project. The development includes a mix of 2 and 3-bedroom apartments and a view of the St. John’s Bridge.
The project needed to achieve a 45 dBA interior noise threshold. ABD conducted a site noise study to capture the frequency content and volume level of the noise sources nearby. We used that data to make recommendations for the building facade, roof deck, and window glazing performance. The proximity of the rail line required a vibration study to provide data for the structural engineer.
ABD’s acoustics services also included recommendations for noise isolation to meet STC and IIC goals, room acoustics in common areas, and mechanical noise and vibration control for the mechanical systems.
