Flexshield sonic curtain panels were used by an Australian construction
company to create a temporary acoustic enclosure designed to contain noise and
dust during a demolition project.
The company was tasked with the removal of terrazzo floor coverings at
the Canberra Centre Ainslie Mall with all works to be carried out at night,
requiring them to comply with stringent noise restrictions.
The temporary acoustic enclosure was clad in Flexshield sonic curtains
and used to completely enclose the demolition machinery. Built using lightweight
scaffold and internally clad with 12mm ply, the enclosure was covered on the exterior
with Flexshield sonic curtain panels to contain the demolition noise.
Ambient noise recorded prior to the use of the mobile noise enclosure
was 55 to 60dB at the entry to the adjacent blocks of flats. During the test
demolition, noise levels of up to 85dB were recorded while the maximum recorded
level when using the enclosure was 66dB.
The construction company’s project manager commented that they would not
have been able to complete the demolition works without Flexshield sonic
