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.

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.

The following table illustrates acceptable minimum levels of lighting (in LUX) in different areas:

FSTC (Field Sound Transmission Class) is now ASTC (Apparent Sound Transmission Class)! ASTM E336 – 19

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!
