Testing
We use independent laboratories for testing:
Riverbank Acoustical Laboratories™
An accredited by the U.S. Department of Commerce, National Institute of Standards and Technology (NIST) under the National Voluntary Laboratory Accreditation Program (NVLAP) as an ISO 17025:2005 Laboratory (NVLAP Lab Code: 100227-0) and for this test procedure. The test reported in this document conformed explicitly with ASTM C423-09a: “Standard Test Method for Sound Absorption and Sound Absorption Coefficients by the Reverberation Room Method.” The specimen mounting was performed according to ASTM E795-05(2012): “Standard Practices for Mounting Test Specimens During Sound Absorption Tests.” A description of the measuring procedure and room qualifications is available upon request.
University of Salford’s Acoustic Test Calibration Laboratory
As part of their internationally renowned acoustics measurement facility, the University of Salford’s Acoustic Test & Calibration Laboratory provides an independent, service for acoustic consultancies, local authorities, construction, product design and other acoustic-related industries. See their UKAS scope here for Calibration and Testing.
Interpretation
In order to demonstrate the effectiveness of our products, we chose to record the best, most accurate measurement of absorption from each laboratory used. In some cases, it is known as the Absorption Coefficient, while in others, it is explained as the Random Incidence Equivalent Absorption Area. We also may use the more commonly known Noise Reduction Coefficient (NRC), which is the measure (NRC) from 0 to 1. 0 being absolute reflection and 1 being absolute absorption of sound waves into the material. Here, we are measuring absorption both among time and frequency.
Mount Types Tested:
Type A Mounting:
The test specimen was laid directly against the test surface. The perimeter edges were exposed, as would be typical of an actual installation of this specimen.
Type D-100 Mounting:
The test specimen was mounted on 100 mm (3.937 in.) thick wood furring strips spaced 300 mm (12 in.) on centers and laid directly against the test surface. The furring strips produced a 100 mm (3.937 in.) thick air space behind the test specimen. The perimeter was sealed with wood and metal framing.
Type J Mount:
The specimen is a set of sound absorbing units installed with one surface in direct contact with the test surface and another in direct contact of the side wall of reverberation chamber. This approximates the corner mounting method typical of the actual product installation. The units were evenly spaced along the walls of the chamber (3 on North wall, 2 on South wall, 2 on the East wall and 1 on West wall).
