Engineers, contractors, and building owners rely on accurate data to specify solutions that enhance occupant comfort while ensuring compliance with industry standards.&nbsp;<\/p>\n\n\n\n<p>Price Industries understands this need, which is why they operate the only NVLAP-accredited noise control laboratory in North America. Their commitment to rigorous testing and the latest standards ensures that their silencers and noise control products deliver verified, repeatable performance in real-world applications.&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Why NVLAP Accreditation Matters<\/strong>&nbsp;<\/h2>\n\n\n\n<p>The National Voluntary Laboratory Accreditation Program (NVLAP) is a globally recognized accreditation that ensures testing laboratories meet the highest standards for accuracy and consistency. In the HVAC industry, this means that silencer performance data from Price Industries is independently verified and highly reliable\u2014giving engineers confidence that the products they specify will perform as expected.&nbsp;<\/p>\n\n\n\n<p>Without NVLAP accreditation, performance claims can vary significantly, leading to inconsistent noise reduction, unpredictable results, and potential occupant discomfort. Price\u2019s NVLAP-accredited lab eliminates these risks by providing certified, trustworthy data that meets or exceeds industry expectations.&nbsp;<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"791\" src=\"https:\/\/www.michiganair.com\/blog\/wp-content\/uploads\/2025\/02\/noise-control-products-nvlap-accredited-sound-lab-brochure-1-1024x791.jpg\" alt=\"Price Industries NVLAP Accredited Sound lab\" class=\"wp-image-1255\" srcset=\"https:\/\/www.michiganair.com\/blog\/wp-content\/uploads\/2025\/02\/noise-control-products-nvlap-accredited-sound-lab-brochure-1-1024x791.jpg 1024w, https:\/\/www.michiganair.com\/blog\/wp-content\/uploads\/2025\/02\/noise-control-products-nvlap-accredited-sound-lab-brochure-1-300x232.jpg 300w, https:\/\/www.michiganair.com\/blog\/wp-content\/uploads\/2025\/02\/noise-control-products-nvlap-accredited-sound-lab-brochure-1-768x593.jpg 768w, https:\/\/www.michiganair.com\/blog\/wp-content\/uploads\/2025\/02\/noise-control-products-nvlap-accredited-sound-lab-brochure-1-1080x835.jpg 1080w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Testing to the Latest Standard: ASTM E477-20<\/strong>&nbsp;<\/h2>\n\n\n\n<p>When specifying noise control products, it\u2019s critical to ensure they are tested to the latest version of <a href=\"https:\/\/www.astm.org\/e0477-20.html\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"ASTM E477 (opens in a new tab)\">ASTM E477<\/a>, the industry\u2019s standard for evaluating silencer performance.\u00a0<\/p>\n\n\n\n<p>The most recent version, ASTM E477-20, sets a new benchmark for accuracy. Compared to older versions, it features tighter reproducibility limits, reducing variability in test results. Some manufacturers still rely on outdated standards, which allow for a wider range of performance fluctuations. This can result in overstated attenuation values and underperforming silencers in the field.&nbsp;<\/p>\n\n\n\n<p>By testing exclusively to ASTM E477-20, Price Industries ensures that the published performance of their silencers is a true reflection of how they will perform in real installations\u2014giving engineers confidence that their designs will meet required noise levels.&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>The RAC: Certified Performance Over Field-Fabricated Return Boots<\/strong>&nbsp;<\/h2>\n\n\n\n<figure class=\"wp-block-image\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"760\" src=\"https:\/\/www.michiganair.com\/blog\/wp-content\/uploads\/2025\/02\/rac-return-air-canopy-catalog-page-1024x760.jpg\" alt=\"\" class=\"wp-image-1260\" srcset=\"https:\/\/www.michiganair.com\/blog\/wp-content\/uploads\/2025\/02\/rac-return-air-canopy-catalog-page-1024x760.jpg 1024w, https:\/\/www.michiganair.com\/blog\/wp-content\/uploads\/2025\/02\/rac-return-air-canopy-catalog-page-300x223.jpg 300w, https:\/\/www.michiganair.com\/blog\/wp-content\/uploads\/2025\/02\/rac-return-air-canopy-catalog-page-768x570.jpg 768w, https:\/\/www.michiganair.com\/blog\/wp-content\/uploads\/2025\/02\/rac-return-air-canopy-catalog-page-1080x802.jpg 1080w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><figcaption> Lightweight and easy to install, the RAC offers an economical solution for return air noise and speech privacy by blocking occupant noise from entering the plenum and preventing mechanical noise from flanking into occupied spaces. <\/figcaption><\/figure>\n\n\n\n<p>Another innovation backed by NVLAP-accredited testing is the <a href=\"https:\/\/www.priceindustries.com\/noisecontrol\/products\/rac-return-air-canopy\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"Return Air Canopy (RAC) (opens in a new tab)\">Return Air Canopy (RAC)<\/a>\u2014an engineered alternative to traditional field-fabricated return boots.\u00a0<\/p>\n\n\n\n<p>Field-fabricated return boots are often assembled on-site, leading to inconsistencies in construction and potential flanking paths, where noise can bypass the intended attenuation system and re-enter the occupied space.&nbsp;<\/p>\n\n\n\n<p>The RAC is designed and tested to eliminate these issues, providing consistent, certified performance with no guesswork.
