Experience Designing Peace and Quiet

Members of the firm belong to the following professional organizations:

From behind the drafting table:

We’re a team of professional, specialized consultants with engineering and architectural backgrounds. We’ve been in business since 2005 and together our group has more than fifty years of combined experience in the field of acoustic and vibration control.

Our firm is just the right size to maintain the hands-on style we prefer. And when the scope or scale of a project calls for additional expertise, we also can partner comfortably with appropriate, outside specialists. What ever the size or complexity of the job, we’re players now, and we can handle it.

An irony of our business is when we’ve done the job right, all our hard work is or should be imperceptible. When we’ve focused our attention on resolving existing or potential noise and vibration issues of a particular project, our clients shouldn’t have to. For us, a job well done is one that enables our clients to work or live in relative peace and quiet.
