ICD 705 Acoustical Testing Considerations for SCIF and SAPF areas

ICD 705 is a wide ranging document that concerns itself with all aspects of site security for secure facilities. Our focus is to provide acoustical testing of SCIF and SAPF areas to satisfy the acoustical testing requirements.

We have provided ICD 705 compliant testing in SCIF and SAPF secure facilities at United States Military and governmental agencies around the world.

From Guantanamo Bay to Bahrain, to Weisbaden, Germany, all around the CONUS (and Pearl Harbor as well) we have worked with contractors of all sizes, as well as directly with governmental agencies to ensure that secure facilities perform according to specification.

We can also provide assistance during the design and construction phase, as well as provide information and design for remediation of SCIF and SAPF areas through field testing and computer based modeling of wall, floor, and ceiling assemblies.

The following parameters as detailed in ICD 705 Version 1.4:

A. Overview
1. This establishes DNI guidelines to protect classified conversations from being inadvertently overheard outside a SCIF.
2. This is not intended to protect against deliberate technical interception of audio emanations.
B. Sound Group Ratings
The ability of a SCIF structure to retain sound within the perimeter is rated using a descriptive value, the Sound Transmission Class (STC). To satisfy the normal security standards of SCIFs, the following transmission attenuation groups have been established:
Sound Group 3 – STC 45 or better. Loud speech from within the SCIF can be faintly heard but not understood outside of the SCIF. Normal speech is unintelligible with the unaided human ear.
Sound Group 4 – STC 50 or better. Very loud sounds within the SCIF, such as loud singing, brass music, or a radio at full volume, can be heard with the human ear faintly or not at all outside of the SCIF.
C. Acoustic Testing
1. Audio tests shall be conducted to verify standards are met. Tests may be instrumental or non instrumental as approved by the AO. Test method used shall be detailed in the CSP.
2. Instrumental Acoustic Tests:
a) Only those with training on audio testing techniques shall conduct instrumental acoustic tests
b) With all SCIF doors closed, all perimeter walls and openings (e.g., air returns, doors, windows, etc.) shall be tested along multiple points to ensure that either Sound Group 3 or 4 is met.
c) Audio test sources shall have a variable sound level output.
d) The output frequency range shall include normal speech.
e) Test speakers shall be placed six feet from the test wall and 4 feet off the floor.
f) Audio gain of the test source shall produce “loud or very loud speech” as defined by Sound Group 3 and 4 levels respectively.
g) As an alternative, instrumented testing may be performed to Noise Isolation Class (NIC) standards. Results shall comply with NIC 40 for Sound Group 3 and NIC 45 or Sound Group 4

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 for more information.

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.

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:

Conflicts of Interest – Consultants that ALSO sell materials and installation services

Almost every week, we hear from prospective clients who are looking for a second opinion of a report (and accompanying bill of materials and installation) they they have received from an acoustical, vibrational, or air quality testing firm or consultant.

Often they are both perplexed and upset by the financial burden that adherence to the report/materials list will cause.

In our opinion, consultants and testing agencies should NEVER be in the business of selling (and/or installing) materials for the following reasons:

1. Consultants should never be in a position where recommending materials adds to the bill. Recommendations for remediation should be based upon facts, rather than added profit.

2. Consultants should always be free to represent the best solution, not the one that is sold or distributed by the consultant.

3. Consultants who have a stake in the effectiveness for materials sold into a project have a conflict of interest between unbiased results and proving that their solutions worked.

4. Consultants (testing firms, and worse yet, material distributors) who sell materials have been known to conduct testing as an afterthought (with substandard tools and methods)

On-Site Acoustic Testing does not sell any products, materials or installation services, nor do we take payment of any kind from materials or vendors that we may recommend as part of our project recommendations.
