Abstract
A project of acoustic treatment of rooms aims to control sound reverberation to ensure acoustic comfort. The designer’s challenge is to combine the aesthetics of solutions with the functionality of acoustic elements. In this context, the development of slotted acoustic panels allows for the combination of design with acoustic performance. This work aims to know the development of a slotted acoustic panel. The idea is to combine slotted MDF wood panels which are supported by PET wool absorbent material. The optimum frequency range chosen refers to human voice, that is between 500 Hz to 2 kHz. The constructed samples were evaluated in reverberation chamber (Laboratory of Acoustics and Vibration - UFSC) and installed in a meeting room. Thus, this environment was analyzed before and after installation, demonstrating that the developed acoustic solution presents excellent control of sound reverberation time of the room.
