Meeting Room Noise Problems

The meeting room had plasterboard and glass walls, an exposed concrete soffit and low pile carpet tiles over a concrete slab floor.

The high level of reverberation significantly hampered the speech intelligibility of meetings, teleconferences and telephone calls conducted within the room.

Meeting Room Soundproofing Solution

To mitigate excessive reverberation in the meeting room, Renzo Tonin & Associates organised to have twelve 1200 x 600 x 100mm Megasorber P100WR-WH(GP) panels attached to the exposed concrete soffit.

The reverberation time was measured by an acoustic engineer at Renzo Tonin & Associates before and after the installation of Megasorber P100. The results are shown below in Fig.1

Before soundproofing installation: The reverberation time at key speech frequencies (250-2000 Hz) was up to 1.3 seconds. Australian Standard 2107:2000 recommends a maximum reverberation time between 0.6 and 0.8 seconds for such spaces.

After soundproofing installation: The reverberation time at the key speech frequencies dropped to 0.4-0.7 seconds, complying with the Australian Standard recommendations. The speech Intelligibility of meetings, teleconferences and telephone calls within the room significantly improved.
