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:

Recommended Lux Levels by Area

Area Nominal Illumination Level in Lumens/Square Meter (lux) Office Space Normal work station space, open or closed offices1 500 ADP Areas . . . → Read More: Light Quality Testing

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.

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

Recently the name of the field insulation impact class rating system which was known as FIIC has been changed to apparent impact insulation class.

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 FIIC now say AIIC.

Before you purchase that new house or condominium…

Over the past 20 years, it’s been increasingly common for home buyers to enlist the services of a home inspector. In fact, many banks make home inspection a precondition that must be met as a part of the loan process! All of the major mechanical systems of the home or condominium should be inspected for quality and functionality, and the overall “fitness” of the building should be assessed. Even if you are just considering renting an apartment for a yearly lease, you should give consideration to having that apartment tested for both noise transmission and ambient noise within the space…if . . . → Read More: Before you purchase that new house or condominium…
