Transportation infrastructure, dense urban settings and the mechanical systems of commercial and industrial facilities can generate significant ambient noise levels impinging on a target design space. The first step in a new design is often a careful measurement of the interior and/or exterior baseline noise environment. Alternately, an existing design might be measured to diagnose noise complaints or confirm compliance with noise regulations. We have extensive experience making a wide variety of noise measurements (STC, IIC, NC, reverberation time, etc.) in all kinds of spaces. Below are some of our projects in which noise measurement and/or testing was critical to the client’s needs or the success of a design.
