We have performed ASTM E336 and E1007 testing on military sites, in government buildings, SCIF locations, and for private contractors. We would love to hear what you need to test.
ASTM E336 is a test method commonly utilized in the construction industry to assess the acoustic performance of building partitions, specifically in measuring airborne sound attenuation between rooms in buildings. The objective is to ensure that the partitions meet the necessary criteria for noise reduction specifications in various settings, such as residential, commercial, SCIF, or industrial buildings. We have experience with military and government SCIF requirements and can generate the necessary reports.
Typically, a team of NOAL staff will arrive on-site with calibrated test equipment, including microphones, loudspeakers, and advanced portable analysis equipment. The test involves generating and measuring loud sound in a designated source room, measuring the sound levels, background noise levels, and absorption in a designated receiving room, and collecting information about the room volumes and partition areas. The results of the test will be presented in a test summary, with further analysis available upon request in the form of a formal, accredited test report. The results are often expressed in terms of ASTC, NIC and NNIC, among other metrics.
In addition, ASTM E336 is often paired with ASTM E1007, which involves measuring tapping machine impact sound transmission through floor-ceiling assemblies and associated support structures in a room below. NOAL staff will utilize a tapping machine during this additional test to assess the sound transmission through the floor assembly.
"Standard Test Method for Measurement of Airborne Sound Attenuation between Rooms in Buildings"
North Orbit is A2LA Accredited to perform ASTM E336 and ASTM E1007 on Certificate 4240.01.
Every test has unique characteristics, so managing cost means managing time and materials. Variables include test location (in the lab or field), which test standard and equipment to use, how much labor is required, what materials we need, and how much data we need to reduce.
