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
  • 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.

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.

Noise, vibration, air, or water quality testing at your facility

Workplace Noise Testing Services

If you’ve built a business, you know that your employee’s health and welfare is a critical part of your business’s overall wellness. The fact is, that workers who are exposed to high levels of noise are susceptible to long-term hearing loss as well as other health related issues. In addition to the physical and emotional toll this can take upon your employee, it can potentially put your business at risk for costly and time-consuming workers compensation actions. The only way to be sure that your employees and partners are safe is to have workplace noise level testing done at your facility.

At On-Site Acoustic Testing we specialize in coming out to your workplace and performing non-invasive work place testing of the equipment and processes in your factory, retail establishment, bar, night club, or office suite. We measure all kinds of noises ranging from heavy industrial equipment to heavy metal bands! We use the very techniques specified by OSHA, MSHA, and other regulatory bodies to make sure that your employees, partners, and patrons are safe. If there are violations, it’s best that YOU are the first person to know about it, rather than an agent from one of the regulatory bodies.

We offer noise surveys, dosimetric testing, noise maps, spectral analysis, and general noise testing of all kinds of workplaces.

Talk to us today at 1-800-665-0080 about workplace noise testing, and find out how we can help!

 

Noise Dosimetry Testing Services

Whether it comes by way of your insurance company, a client’s request for an audit, ISO certification, or the long arm of OSHA and/or MSHA, at some point your company is likely going to need to provide documented evidence of the noise levels to which your employees are exposed to during their working day. Simply taking noise level measurements in the area where workplace activities are in process is not enough. Those readings can easily give you levels that are too high, or worse yet, too low! The only way to properly gauge the exposure to noise and sound that your workers are actually exposed to is through noise dosimetry.

Personal noise dosimeters are simply noise level meters that are designed to be worn by workers during their shifts. Best practices for the collection of this information will require that an employee wear the noise dosimeter for the entire duration of their shift…and it’s crucial (for the sake of accuracy) that the period of testing actually reflects their normal working day! Even if it’s not possible (for what ever reason) to take measurements for the entire duration of their working shift (or in the case that their working shift is longer or shorter than the 8 hours that OSHA and/or MSHA mandates) it’s possible to extrapolate the likely average level to which they are exposed to. This measurement is called the TWA, or time weighted average. Simply put, it’s a calculated number that is based on the noise level that they are exposed to during the measurement period…shortened or lengthened to meet the criteria for an eight hour period.

We use a few different dosimeters, depending upon the particular application. We have units that are safe for combustible areas (intrinsically safe) as well as units that are lightweight and non-invasive. It’s all dependent on your application, and requirements. Our most advanced noise dosimeters allow us to provide you with such metrics as: time weighted average, peak levels, minimum levels, and number of peak events. We are able to deliver to you detailed information in spreadsheet and graphic formats that detail the average (and/or peak) noise levels to which your employees are exposed to on a minute by minute basis.

Contact us today to find out how we can provide you with the information you need to safeguard the hearing safety of your employees, as well as inoculate your company from the risk of legal action based upon avoidable noise violations.

OSHA noise consulting

In today’s regulatory environment, if you aren’t testing your workspaces (and employees) for noise exposure you are putting your company at risk. On-Site Acoustic Testing is here to support your organization by providing you with qualified OSHA noise consultants who will provide you with an accurate assessment of your sound levels.

Our team members will perform measurements in your workspace and also initiate dosimetric (dosimeters are sound level meters that are worn during the working shift by your employees) testing to determine the time-weighted average (TWA) of noise that your employees are actually exposed to while they are performing their daily activities.

We will work with you to analyze the results of the testing, determine which (if any) employees are potentially at risk, and then help you implement a program for hearing protection devices. We will also help you implement a hearing conservation program at your organization. Our OSHA noise consultants are familiar with the myriad of OSHA (MSHA as well) regulations, and the ASTM and ANSI standards they are based upon.

On-Site Acoustic Testing will assist your company in maintaining a safe and productive workspace. Contact us today to speak directly with us about OSHA related noise measurement services.

We provide services nationwide, and emergency “rush” services are available.

Call us at 1-800-665-0080 for immediate service.

We solve nightclub, bar, or restaurant noise related issues!

We all know that music and night life are truly tied together at the hip. Getting (and keeping) your patrons in just the right mood is great for business, and crucial in making your place the place to be. That said, there is a fine line between sound levels that are enjoyable and exciting, and those that are uncomfortable, or worse yet, unsafe! At On-Site Acoustic Testing, we will assess your current sound (both ambient and music) levels, and craft a compelling (but safe) soundscape for your patrons. Essential, as well, is making sure that your front-line staff are safe while performing their daily and nightly duties. As is well known, OSHA (Occupational Safety and Health Association) has placed limits on the total noise exposure that employees may absorb during their working day (or night). Violating these regulations is bad for employee’s short and long term health, as well as their job performance! Additionally, it could open up troublesome and expensive worker’s compensation claims. Knowing the limits (and where your establishment falls) BEFORE problems emerge, is the only way to go.

We will measure all front and back of house areas, and calibrate your sound systems for you. We can also help craft a spectral sound balance that lets people enjoy and feel the music, while still making conversation possible.

Call us today at 1-800-665-0080 to speak with one of our consultants about how we can protect your patrons, your employees, and your bottom line!

Elevator and escalator ride quality testing – ISO 18738…

Whether you are an installer or the end user, independent third party testing ensures that you are privy to the most accurate and unbiased information regarding the performance of your elevator or escalator. We utilize the industry standard PMT EVA-625 triaxial elevator and escalator ride quality monitoring system with the most recent firmware and analysis software. The PMT EVA-625 (ours is fitted with the optional USB storage option) affords us the opportunity to potentially test multiple elevator banks during a single site visit. Although several different measurement standards are supported, we find that most of our clients prefer the unit be set to deliver results consistent with the specifications set forth in ISO 18738 Measurement of Ride Quality: Part 1 Lifts (elevators).

Within these standards, there are multiple data sets that may be acquired during the testing process and careful analysis of theses results will help to pinpoint trouble spots with ride quality as well as assist facilities managers with keeping track of trends in equipment condition. We can provide you with the relevant data set for your consultant to analyse, or we can provide turnkey analysis services helping you pinpoint performance problems.

Additionally, we provide other related services such as vibration testing of elevator hoist units,  FFT analysis of motors and other moving elements, as well as a detailed spectral analysis of in-cab performance (which is surprisingly important in the subjective assessment of elevator and escalator ride quality). This data can then be used to make targeted improvements to both moving components and in-cab elements.

Contact us today at 1-800-665-0080 to schedule testing of your elevator or escalator!
