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.

Factory Noise Testing – Noise, Vibration, and Air Quality tests in factories of all types!


Whatever your product, whatever your industry On-Site Acoustic Testing is here to provide testing to make sure that your employees and partners are safe! When it comes to noise, vibration and air quality concerns, there is no room for error or uncertainty. This is why we use high precision instruments to survey noise and air quality conditions in your facility, providing you with the information you need to make informed decisions when it comes to industrial hygiene. The effects of high decibel sounds are well documented, with well known effects such as hearing loss and tinnitus among the known ill-effects. Even if sound levels are below the thresholds that OSHA and other agencies specify, noise pollution can adversely effect productivity as well as employee morale.

Excessive vibration is tough on workers, often a contributing factor to shorter than expected tool and motor life, as well as a prime factor in out of specification products. We can perform FFT and other kinds of vibration testing (including triple axis vibration testing) in order to determine specific levels of vibration and track down their root causes.

The detrimental effects of air pollution can be even more insidious, ranging from minor irritations of the sinuses to much more serious conditions including various cancers and other potentially fatal illnesses. We can test for the presence of hundreds of compounds including metals, gasses, generalized particulate matter and other airborne contaminants.

Vibration – V-V-V-V-Vibration testing services in the workplace

Much has been written recently about repetitive stress injuries. Typically, existing studies have focused on the kinds of repetitive stress injuries that workers sustain at the computer keyboard, or sustain from injurious activities such as sitting in an office chair for years at a time! There is another side of these injuries that is becoming more fully recognized, and that is the deleterious effects of excessive vibration.

Workers who are exposed to high levels of vibration can suffer from many of the same kinds of injuries such as vascular damage (VWF – vibration white finger) and Raynaud’s Disease as well as other changes that may manifest in the tendons, muscles, or bones.

Tragically, while many of these injuries can take months or years to resolve, many if not most of them were (are) preventable with proper attention being given to instituting anti-vibration measures in the workplace.

Contact us at 1-800-665-0080 to speak with a consultant today, or email us at: sales@onsiteacoustictesting.com

The first step to preventing these injuries is in rooting out areas in the workplace where workers are subject to high levels of vibration. Sometimes this vibration is an unavoidable by-product of the equipment (for example – jackhammers and other pneumatic-impact devices) but often vibration is a sign that machines, or parts of machines such as bearings or driveshafts may be worn, out of balance, or otherwise defective.

We offer both real-time traditional and FFT measurement of vibration, as well as long-term multi-axis vibration logging services.

On-Site Acoustic Testing has the equipment and know-how to ascertain the operational health of your equipment, and help your company set safe limits for the vibrational exposure of your employees.

Types of Acoustic and Vibration Testing Services

We are pleased to offer a wide variety of acoustic testing protocols and consulting services nationwide and worldwide. Here is a sampling of what is available:

  • Noise measurements in standard decibel ratings (dB-A weighted) – Used for compliance with local, state, and/or federal requirements
  • FIIC / AIIC – Field / Apparent Impact Insulation Class  – Used for measuring the sound transmission of a ceiling/floor structure in commercial spaces, houses, and apartments
  • FSTC / ASTC  – Field / Apparent Sound Transmission Class – Used for measuring the sound transmission of a wall structure in apartments, houses, commercial spaces and condominiums
  • Noise Dosimeter Testing – A simplified sound level meter is attached to an individual in order to assess their noise exposure during a predefined period
  • Noise Surveys – Often required by HUD and other Federal agencies when properties such as houses, apartments and condominiums are located near noise sources like Airports, Train Tracks, Highways and Freeways, Manufacturing Plants, Sewage Treatment Plants, and Power Stations noise surveys are timed studies detailing the noise levels for a specific time period
  • Noise Spectrum Analysis – Used for determining what frequencies in the audio band a particular noise is coming from when measured from an adjacent house, apartment, condominium or commercial space
  • Vibration Analysis – Used for tracking down vibration coming from machinery, and sometimes to determine whether a machine assembly is in balance. We can provide both real-time and long-term logging of vibrating structures including FFT analysis.

We are able to offer most ASTM, MSHA, and ISO tests in the acoustic area. Please contact us about your specific requirements for your commercial space, condominium, or apartment.

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.
