Performing ASTM E336 at a construction site

Architects, builders, and construction companies use sound transmission loss results to ensure code or other third-party compliance. Consultants use the data to make accurate predictions of sound levels the occupants or active or passive listeners will hear on opposite sides of partitions under specific noise conditions. We use field testing per ASTM E336 when a quantifiable sound transmission loss rating is needed to satisfy these requirements or when no laboratory data is available. Clients may use field test data to assure other third-party specifications or as a marketing tool to establish a competitive advantage.

Acoustic sound survey at industrial site

As with our laboratory testing, North Orbit has many years of experience designing and conducting specialized field sound testing programs. We perform sound hygiene surveys to help businesses comply with OSHA noise level regulations. We conduct pre-construction environmental acoustic surveys to help architects customize sound mitigation to their building site. 


We have tested everything from air and road traffic noise to fitness centers, gun ranges, and industrial sites, and we enjoy a new challenge.

Sound power testing on HVAC system in-situ

We use noise level dosimetry to measure employee exposure. We monitor industrial clients’ noise load by mapping whole areas and measuring each component to determine contribution. When OSHA requires remediation, we sort and rank contributions and choose equipment and locations not to exceed recommended doses.


Acousticians and engineers use sound power levels when designing noise control of their building HVAC and other mechanical systems. Knowing sound power levels helps set, then satisfy, customer expectations and comply with third-party regulations.
