Information about OSAT

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.

A brief overview…

On-Site Acoustic Testing provides nationwide acoustic, vibration, indoor air quality, light intensity, thermal and spectrum testing to military, commercial, and residential clients.

We are proud to offer testing of SCIF and SAPF areas to ensure compliance with ICD 705 standards, and have conducted testing for all four branches of the United States Military. We have also conducted testing for the United States Nuclear Regulatory Agency, The Office of the Inspector General, as well as many other state and municipal governmental agencies.

Our noise testing services include: noise surveys for neighborhoods, municipalities, state and federal agencies to assure compliance to community standards. We provide ASTC and AIIC testing services to architects, construction firms, property management companies, and individual residential users. We can furnish ISO noise declarations for manufacturers for use in machinery destined for EU community installation.

We provide OSHA compliance testing (including noise dosimeter testing for employees), as well as general shop floor, and machine/machine room noise level and indoor air quality testing for our commercial and industrial clients.

We can provide testing to ASTM, ISO, and ANSI standards for many applications, testing your product at your location, our location, or an end user’s location.

We offer indoor air quality testing for a wide spectrum of contaminants ranging from common molds to compounds generated during the manufacturing process.

Testing is only the first step, we offer noise abatement services as well. We work with leading isolation materials manufacturers to custom tailor their products to your application, with an eye towards minimizing costly downtime and maximizing results.

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.

Distribution Center Testing

The amount of packages moving across the United States each and every day is truly staggering. If you’ve ever been in a large scale distribution center (such as the distribution centers for FEDEX Ground – we’ve tested many of their facilites) you’ll quickly realize that no matter how much automation has taken the place of humans, there are still many women and men working along side of the machines.

While machines are (mostly) insensitive to noise, light, and air quality issues, the same cannot be said for the people working inside the facility.

That’s where On-Site Acoustic Testing comes in. We can provide the testing that you need to make sure that your employees are safe.

Whether you are in need of noise level testing, air quality testing, or light quality (or level) testing, we can get you the information you need to ensure OSHA compliance.
