We utilize a high-end, avant-garde laboratory for autonomous control capabilities. Prior to mass production, we enforce rigorous pre-production sample testing. This ensures that every batch delivered meets outstanding quality standards.
As illustrated, external noise of 80.1 dB is reduced to 36.4 dB or lower within the internal laboratory environment, guaranteeing accurate acoustic performance results.
All reports meet American Standards. Sound testing is conducted with Intertek to ensure compliance and reliability.
With over 70 years of experience in noise control and acoustic engineering, we provide one-stop solutions from concept to completion. Our services include solution consulting, structural design, fluid calculation, manufacturing, and installation.
We serve various fields including aerospace, commercial buildings, industrial engineering, power equipment, and medical audiometry.
