Flexshield sonic curtains were utilised by an Australian construction company as a noise control solution for a demolition project.

Flexshield sonic curtain panels were used to clad a temporary acoustic enclosure built to contain noise and dust during the demolition of terrazzo floor coverings at the Canberra Centre Ainslie Mall. Since all the works were carried out at night, the company had to adhere to stringent noise restrictions.

Built from lightweight scaffold and internally clad with 12mm ply, the construction noise control enclosure completely enclosed the demolition machinery with its exterior covered using Flexshield sonic curtains to contain the demolition noise.

Ambient noise measurement taken prior to the installation of the mobile noise enclosure was at 55 to 60dB at the entry to the adjacent blocks of flats. Demolition noise levels of up to 85 dB were recorded during the testing phase while the maximum recorded level using the enclosure was 66dB.

The construction company’s project manager observed that they would have been unable to execute the project if they didn’t have the Flexshield sonic curtains, given that constructing a fully engineered acoustic hoarding would have involved great expense and caused considerable delay to the schedule.
