Large public venues including school auditoriums, multi-function halls, and conference centers have long been troubled by stubborn low-frequency reverberation. Traditional porous acoustic materials work well for high-frequency noise but fail t...

Large open spaces such as school auditoriums, multi-function halls and conference centers are troubled by severe mid-low frequency reverberation. Traditional porous acoustic materials perform poorly on 250Hz-1000Hz low-frequency noise, which e...

Porous acoustic materials such as fiberglass and polyester fiber perform excellently in absorbing mid-to-high frequency sound, yet they show limited effects on stubborn mid-low frequency noise ranging from 250Hz to 1000Hz, including HVAC vibra...

School auditoriums are multi-functional spaces that host lectures, performances, assemblies, and community events. Clear sound transmission is critical for effective learning and engagement, yet many auditoriums suffer from excessive reverbera...

Grooved acoustic panels are precision‑engineered resonant absorbers designed to target mid‑low frequency noise (250 Hz–1000 Hz) that standard porous materials often struggle to control. Featuring a rigid substrate with precisely cut linear groov...
