Architectural Soundproofing Requirements
Melbourne Airport T4 terminal bus bay required an acoustic material to be fitted onto the ceiling to reduce the noise in the hectic area. The consulting
engineers required that the soundproofing material meet the following key specifications:
excellent sound absorption of both low frequency (such as 250Hz) and mid frequency (such as 1,000 Hz)
high sound absorption capacity, with a minimum NRC of 0.80
suitable to outdoor application
seamless acoustic ceiling system that is cost effective to install
Megasorber P25, a 25mm thick acoustically tuned polyester-wool panel, with fireproof, sound-absorbing G8 Soundmesh® facing, was used
to soundproof the ceiling.
Joins were sealed with colour matching Soundmesh G8 tape.
The soundproofing panels were firmly installed with Megasorber A200, a high tack and high temperature resistant adhesive utilizing the latest polymer-alloy
