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.

Sound Intensity Testing

On-Site Acoustic Testing, LLC offers sound intensity testing of machinery of all types and sizes for a variety of mission requirements.

While sound intensity testing is a requirement for ISO noise declaration documents (in order to determine sound power) it can also be incredibly useful in determining the radiating pattern of equipment. Using our sound intensity test equipment, we are able to provide a visual representation showing the exact radiating pattern both by intensity as well as by frequency.

This process can also be used for leak detection, in order to determine where (a door, for example) is leaking around a seal. Often this can be the most effective way to diagnose a visually correct, but failing wall, window, or door partition.

Contact us today at 800-665-0080 or project@osatusa.com in order to discuss your project requirements.

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:

HIPAA and your practice….

As you probably already know, T\the Health Insurance Portability and Accountability Act of 1996 was enacted by the United States Congress and signed by President Bill Clinton in 1996.

Title II of HIPAA, known as the Administrative Simplification (AS) provisions, requires the establishment of national standards for electronic health care transactions and national identifiers for providers, health insurance plans, and employers.

What does this mean for your practice?

Whether you are a medical doctor, dentist, mental health professional, or other health care provider it means that you are responsible for maintaining the confidentiality of your patient’s records.

You’ve probably already paid close attention to your record keeping, billing, and client contact protocol, but have you given thought to maintaining the privacy of your clients while they are in your office?

Many office suites were designed and built prior to the implementation of the HIPAA Act and even offices constructed long after the start of the HIPAA Act may not have been constructed in a way that ensures the privacy of your patients.

Sound transmission between examination rooms is a common issue in many offices. It’s simply unacceptable for one patient to be able to overhear the private conversation between you and your staff with another patient.

We can provide testing to determine the Sound Transmission Class (STC) and the Speech Intelligibility Index (STI) of the examination rooms, private offices, and other areas of your facility to determine whether unwanted sound transmission between spaces is present.

Should testing disclose a problem, or if you’re already aware that your office has a problem, we can assist you in determining the correct materials that will be necessary to fix the problem.
