FIIC / AIIC – Field Impact Insulation Class Testing Services / Apparent Impact Insulation Class E1007 – 14

Field Impact Insulation Class (now known as Apparent Impact Insulation Class) measures a floor/ceiling assembly’s resistance to the transmission of structure-borne or impact noise. Virtually all states and municipalities have set guidelines for the minimum FIIC (AIIC) test rating that a building may have, and it’s not at all uncommon to find minimum FIIC (AIIC) ratings inserted into requests for proposals from architects and other designers.

Performing an FIIC (AIIC) test requires a specialized piece of equipment called a floor tapper. This machine can be likened to an internal combustion engine that features exposed pistons which are mounted in a manner in which they strike the floor in a repetitive sequence. The specifications for this machine are contained in the ISO 140 and ASTM E 413,  E 492 and E 1007 – 14 specifications. This machine generates a controlled amount of impact noise which is then measured in the room below the room in which the tapping machine is operated.

On-Site Acoustic testing utilizes the Bruel & Kjaer Type 3207 Tapping Machine in conjunction with a Bruel & Kjaer 2260 and 2270  sound level/analyzer meters running the most recent Building Acoustics software.

We are able to provide commercial and residential tenants, building managers, architects, contractors, insurance companies, and governmental agencies FIIC (AIIC) ratings for any building. Call us today to talk about your impact sound problem, whether it involves air handling equipment or upstairs neighbors that tap dance even whilst asleep!

On-Site Acoustic Testing provides FIIC (AIIC) Testing services in all parts of the United States according to ASTM guidelines, and tests through much of the rest of the world to ISO standards.

Indoor Air Quality Testing

Indoor air quality is one of those things that people just don’t spend very much time thinking about…at least until their family or employees start getting sick. While there is more awareness in the manufacturing/industrial world, it’s our opinion that there is still a lack of awareness concerning this important issue. That said, the problems are many times magnified when talking about multi-unit dwellings!

On-Site Acoustic testing can provide indoor air quality testing services for the following agents (and to ASTM/ISO/ANSI standards)

  • Temperature
  • Humidity
  • Carbon Dioxide
  • Carbon Monoxide
  • Mold and other bacteria
  • Particulate Matter and other dust
  • Pharmaceutical agents
  • Organic chemicals
  • NH3
  • CO
  • HCN
  • H2S
  • NO
  • NO2
  • SO2
  • Chrome
  • Lead
  • Phthalates
  • Silica
  • Stainless Steel
  • Iron
  • Mild Steels
  • Solvents

Our expert engineers will develop an individualized profile to first and foremost make sure that the problem is fully diagnosed. Often this can be accomplished relatively quickly via a single day broad spectrum sampling session, followed by submission to one of the regional ISO certified labs we utilize for sample analysis. In other cases, a more detailed approach may be necessary, which could include partial wall dis-assembly, robotic sample collection (for inaccessible duct work), and flooring removal.

After the analysis has been completed, we will develop a treatment protocol that will neutralize the contamination issues and render the treated areas much less susceptible to future recurrence of contamination.

FSTC / ASTC Field Sound Transmission Class testing services / Apparent Sound Transmission Class – ASTM E336 – 14

FSTC (ASTC) Testing Services –Field / Apparent Sound Transmission Class Tests

FSTC (ASTC), or as it’s formally known Field / Apparent Sound Transmission Class is a double digit number that refers to the sound transmission properties of a wall structure. It may also be applied to measure the sound transmission properties of a window or door unit. Virtually all states and municipalities have set guidelines for the minimum FSTC / ASTC test rating that a building may have, and it’s a vital part of the International Building Code.  It’s not at all uncommon to find well-above-minimum FSTC / ASTC  test (and related FIIC / AIIC) ratings inserted into requests for proposals from architects and other designers especially for luxury housing. The most common standards for testing in the United States include the ASTM E90, ASTM E336 and ASTM E413 standards, while in European Union countries the ISO 140 and ISO 717 standards are used.

Performing a FSTC / ASTC test requires some specialized equipment, the first being an omni-directional sound source. This just means a sound source (speaker) that radiates sound in all directions equally, quite unlike a typical speaker which radiates most of its sound to the front. This ensures that the room is equally driven by sound pressure in all directions. Typically this is achieved by utilizing a multi-driver speaker systems that resembles a large soccer ball…think of each of the black sections as a speaker! The Bruel & Kjaer 4292 speaker is probably the best known of the current crop of omni-directional sound sources, and our personal reference unit. This unit is placed in what is called the sending room and then switched on, in order to excite the wall structure (and other structures that comprise the room) so that the resultant noise may be measured on the other side.

Secondarily, a sound level analyzer is required to accurately measure the sound in the room on the other side, which is named the receiving room. We utilize a  Bruel & Kjaer 2260 and 2270  sound level/analyzer meters running building acoustics software BZ 7204 and BZ 7229 which is capable of providing results compliant with ASTM, ISO, DIN, BS, and NBE among others.

We provide commercial and residential tenants, building managers, architects, contractors, insurance companies, and governmental agencies STC testing services and  ratings for any building. Call us today to talk about your noise transmission sound problems.

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.

Logistics Center Testing

Let’s face it, loading docks are hot, noisy, and subject to carbon monoxide emissions from even the cleanest running rigs.

While most packaged products are (mostly) insensitive to noise, light, and air quality issues, the same cannot be said for the people working on the loading docks.

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.

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.

FSTC (Field Sound Transmission Class) is now ASTC (Apparent Sound Transmission Class)! ASTM E336 – 14

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.

ASTM E336 – 14

Standard Test Method for Measurement of Airborne Sound Attenuation between Rooms in Buildings

FIIC (Field Insulation Impact Class) is now AIIC (Apparent Impact Insulation Class)! ASTM E1007 – 14
