What Quiet Mark does
Quiet Mark is an independent third-party acoustic certification organization founded in 2012 in London, UK, operating as the commercial trading arm of the Noise Abatement Society, a UK charity established in 1959. The company evaluates products from manufacturers and brands across 60+ product categories — spanning home appliances, kitchen equipment, building materials, HVAC, office acoustics, and industrial equipment — through purpose-built laboratory testing combined with declared technical data analysis and expert acoustician assessment. Only the top 10-20% quietest products in each category receive Quiet Mark certification, enabling consumers, architects, and specifiers to identify verified low-noise solutions.
The company generates revenue through per-product certification fees paid by manufacturers, brand partnership and listing fees for premium visibility on its platform, and laboratory testing services conducted in partnership with specialist acoustic labs including Anderson Acoustics, HEAD Acoustics, and Intertek. Quiet Mark has certified over 1,000 products from 90+ brands including Philips, Samsung, Dualit, KitchenAid, Magimix, Elvie, and STIHL. Distribution occurs through major UK retail partners (John Lewis, Harrods, Currys, Argos, Howdens), the NBS construction specification platform for architectural projects, and the company's own regional websites serving the UK, USA, Canada, and Europe.
The business operates with a headcount of 1-10 employees and is owned by the Noise Abatement Society, a nonprofit foundation. Its go-to-market follows a B2B2C model: manufacturers pay for certification, while end consumers discover certified products through retail listings, media coverage, and educational content including the Acoustics Academy, Quiet Mark Podcast, and Quiet Times newsletter. The company maintains RIBA-approved CPD status, partnerships with Good Housekeeping Institute in both the UK and USA, and serves as Official Partner of The Sound of the Year Awards.
