Building Acoustics Testing Services – ASTC, AIIC, OITC, and RT

We offer a full variety of building acoustics field testing services that are geared towards military and commercial clients.

Using the most current ASTM (and/or ISO) standards, as well as industry leading equipment, we perform building acoustics measurements throughout the United States and world.

We work with all four branches of the military, federal, state, and local governments, as well as with builders, developers, and architects to verify that building partitions meet their required field tested values.

While our services are geared towards governmental and commercial clients, we do work with homeowners and condominium owners to provide testing services, most often of flooring installations.

The most common building acoustics testing services that we offer are:

ASTC – Apparent Sound Transmission Class – which is used to determine the airborne sound transmission values of wall and floor partitions. This testing has implications for secure (SCIF and SAPF) areas, as well as for general residential or commercial use buildings.

AIIC – Apparent Impact Insulation Class – which is used to determine the structure borne (impact sound) transmission of floor partitions. This testing is most often performed in a residential setting.

OITC – Outdoor Indoor Transmission Class – which is used to determine the airborne sound transmission of the exterior facade of building elements, such as walls, windows, and roof partitions. This testing is often performed on buildings that must be proven to be secures (such as SCIF and SAPF) areas, as well as general residential or commercial use buildings.

RT- Reverberation Time – which is used to determine the length of time that sound takes to decay within an enclosed space. This testing is always performed in conjunction with ASTC, AIIC, and OITC testing, as it is an integral part of the calculation when performing those testing protocols. It can also be performed to determine the suitability of a room for a particular task. Long reverberation times are pleasing in a concert hall (for example) but harmful to speech intelligibility in a classroom or subway tunnel.
