Noise Criteria

The first step to an acoustically well designed mechanical system is the establishment of proper and realistic noise goals. Our recommendations are based on not only standards and published guidelines (ASHRAE, etc.), but our experience as well. Impacts of stringent noise criteria, where applicable, are always discussed with clients and design teams.

Equipment Selection

Not all mechanical equipment is created equal. Our recommendations regarding selection of one type of fan vs. another, for example, may save a mechanical system design money in noise control efforts in the overall design of a system. Our theory is that the best noise control method is to use none at all (when possible). If a quieter noise source is selected from the beginning, the job is done.

Sketches and Drawing Markups

A picture is worth a thousand words. Our sketches and drawing markups help convey information regarding the acoustical design of a mechanical system.

Noise Data Review

When available, we can review all noise data for mechanical equipment and model the effects of the overall system noise. This can be usefull in estimating whether a particular system design will meet it noise criteria goals, or if outdoor equipment will achieve noise regulation levels, for example.

Vibration Isolation

Many times noise control of mechanical equipment is a function of isolating the vibration produced by the machinery from the building. Many times these details are left to contractors. Proper implementation of vibration isolation often requires more than simple product selection. Our experience with implementing effective vibration isolation is a very valuable service to add to your project.
