Development of Folded Expanded Metal Mesh with Sound Absorption Performance [PDF]
Applied Sciences, 2021 Reverberation time (RT) is an important factor affecting the quality of indoor acoustics. Using sound-absorbing materials is one method for quickly and effectively controlling RT, and installation in the ceiling is a common location. Sound-absorbing ceilings come in many forms, with light steel joist ceilings commonly used in office spaces, classrooms,
