This project was an acoustic renovation for a multi-purpose auditorium in a K-12 school. The original space had long reverberation time, especially in the mid-low frequency band, leading to muffled speech and uneven sound distribution. Student...

Large educational multi-function halls typically face prominent mid-low frequency acoustic problems, such as long reverberation, muddy sound and poor speech intelligibility. Ordinary porous materials cannot effectively improve low-frequency no...

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...
