Does using polyester fiber sound-absorbing panels in open-plan offices really improve employee productivity?
2026-07-28
Yes. The biggest challenge in open-plan offices is speech intelligibility interference. Covering key areas of the ceiling and walls with polyester fiber sound-absorbing panels can effectively reduce ambient background noise by 5-10 dB and lower the speech interference level (LPR) by one level, reducing the number of times employees are distracted by noise. Real-world testing shows an improvement in cognitive focus of approximately 15%.
