In commercial and public construction projects, the evaluation of acoustic materials is gradually shifting from parameter publicity based on product manuals to performance verification based on third-party laboratory testing and on-site acceptance. More and more general contractors and owners require suppliers to provide complete third-party test reports before bidding, and take on-site acoustic acceptance results as an important basis for project final acceptance.
According to industry practice, the core indicators that need to be tested and verified include: noise reduction coefficient (NRC), fire resistance grade, formaldehyde emission and VOC content, impact resistance, moisture stability, etc. High-quality suppliers usually cooperate with internationally recognized testing institutions to carry out full-performance testing of products, and issue standardized test reports that can be used for project approval and acceptance. At the same time, on-site acoustic testing after installation can verify the actual reverberation time and noise reduction effect of the space, ensuring that the project effect matches the design goal.
Analysts pointed out that the popularization of third-party testing and acceptance mechanism will squeeze the market space of products with false parameters and shoddy quality, and further promote the standardized development of the industry. Acoustic material manufacturers that focus on product quality, have complete testing systems and stable mass production performance will gain more trust from owners and contractors, and the industry concentration will be further improved.
