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.

Modeling of walls, floors, and windows

Sometimes you start out with the best of intentions, a veritable roadmap to success…but someone, somewhere along the way drops the ball.

That’s where we come in (along with our modeling software) assessing what you already have in situ, and determining what will be necessary for fulfillment of your mission.

We can model virtually any wall, ceiling, floor, window or HVAC structure in order to determine the correct remediation to bring your building partition into compliance.

Spectrum Analysis

Sure, you can measure noise (of all kinds) with your iPhone or Android phone. That may (or may not) tell you something regarding the noise level in your facility or area. Truth is, though, that’s not the whole picture.

What is really important is the actual distribution of the frequencies.

That’s where spectral/spectrum analysis comes into play.

We can measure in 1/1 or 1/3 octaves the actual noise levels from 8 Hz on to the 20 kHz band. If necessary we can actually perform subsonic, or ultrasonic measurements to determine the actual noise emissions in situ.

Contact us at 800-233-8700 or project@osatusa.com for more information.

Thermographic (FLIR) Testing

We can provide expert imaging of equipment, rooms, and building envelopes. Using infrared sensitive equipment, we are able to capture thermal images to pinpoint hot spots on electrical panels (or equipment surfaces), energy loss through walls, windows, doors, and other building facade elements.

Both spot readings and average temperatures of equipment and processes can be acquired, accurately and safely.

Additionally, thermal images can help pinpoint areas where sound may be leaking from area to area.

This technology combined with Sound Intensity Testing and Image Mapping, can provide the required information to diagnose and remediate even the most difficult sound leakage issues in SCIFS and SAPF’s (and other secure areas)

Light Quality Testing

Great lighting makes any room look better…that’s something that you probably would expect to hear from an interior decorator, but the truth is that proper lighting is essential for any and every workplace, restaurant, or retail establishment.

On-Site Acoustic Testing can provide lighting surveys (in LUX or Footcandles) to determine whether your lighting is suitable for the area and purpose.

We also provide ultraviolet light (UVA, UVB, and UVC) testing (commonly found in printing and other production environments).

The following table illustrates acceptable minimum levels of lighting (in LUX) in different areas:

FSTC (Field Sound Transmission Class) is now ASTC (Apparent Sound Transmission Class)! ASTM E336 – 19

Recently the name of the field sound transmission class rating system which was known as FSTC has been changed to apparent sound transmission class (ASTC).

What does this mean, to you, the end user?

The simple answer is: not very much!

The test is still conducted using the same basic methodology, meaning that the equipment and testing process is largely the same.

So be aware that test results that used to say FSTC now say ASTC.
