Top 10 Acoustical Testing Considerations

New Brochure Provides Tips to Optimize Your Product Testing Experience


CEDAR PARK, Texas, November 11, 2020 How well do you know your products  If you have never tested your products at an acoustical testing laboratory, you probably don't know them as well as you should.  The information gained from acoustical testing is an essential part of architectural specifying and manufacturing and may have an impact on your customers' satisfaction, contracts, and bottom line.  Testing shows the acoustical performance of your products and quickly identifies leaks and underperformance issues that can lead to unhappy customers and possible legal actions.  In some cases, in an effort to satisfy ratings requirements, manufacturers can over-design their products to ensure conformance  and acoustical testing can help identify those elements.  At ETS-Lindgren, we understand contracting for acoustical testing can be a daunting experience, especially for a new product.  To simplify the process, we created a new "Top 10 Considerations for Acoustical Testing" brochure to provide guidelines to optimize your acoustical product testing experience before, during, and following the actual test of your product.


"Our veteran team of acoustical test engineers and technicians do more than simply test your product," said Dr. Douglas Winker, Product Line Manager for Acoustics with ETS-Lindgren.  "We are happy to help to our customers prepare for acoustical testing, discuss and witness the actual testing, as well as evaluate the test results.  When a new product is being tested before a critical market launch, we can lend our expertise to review the test data in order to point out areas where the product is over-designed and exceeds the industry requirements.  This partnership with our customers often results in significant cost savings for a product line and a successful product launch," added Dr. Winker.


An example of over-designing a product: Architects typically call for Sound Transmission Class (STC) ratings for windows and other noise isolation partitions in buildings; these ratings are produced by an ASTM E90 test that can only be conducted in a test laboratory.  Because many manufacturers don't have access to test laboratories during their design process, they may include several unnecessary additional components, such as coatings and heavier casing materials.  A series of laboratory tests with detailed report data can identify those extraneous components, resulting in their possible modification or elimination while still meeting the specified rating.  Acoustical testing of a new product in this case can maximize the return on your testing investment.


The "Top 10 Considerations for Acoustical Testing" brochure is the result of ETS-Lindgren's decades of experience in acoustical testing.  We test a wide range of products in our accredited Acoustic Research Laboratory (NVLAP Lab Code 100286-0) located at our headquarters in Cedar Park, Texas.  In addition to standardized testing, our Acoustic Research Laboratory (ARL) conducts customized test programs to address customer-specific product research and development needs, provide independently proven product noise emission information, and ensure product compliance requirements.  Our ARL is comprised of multiple acoustic test chambers, including a reverberant chamber suite used for determining sound transmission loss, sound absorption, and noise isolation, in addition to a hemi-anechoic chamber used to measure noise emissions and sound power determinations.  The entire laboratory operates under a quality system that meets the strict requirements of ISO/IEC 17025: 2017 and general requirements for the competence of testing laboratories.


So what do you need to know to maximize your investment in acoustical testing  Our veteran acoustical team shares their Top 10 tips from selecting the test lab, to preparing your product to expedite test time, to reviewing the test data obtained on your product all to ensure a successful acoustical test experience and high return on your investment.
