Echohush Cosmo, an innovative new acoustic panelling from soundproofing experts, Pyrotek Noise Control was installed to enable students and teachers to communicate effectively without the echo bouncing off the hard surfaces of the gymnasium.
Heggies’ acoustic consultant, Martin Davenport conducted a series of tests in the empty gymnasium prior to the installation to reveal a reverberation time (RT) well in excess of the recommended measurements for building interiors as stipulated by the Department of Commerce Schools Facilities Design Standard.
According to Davenport’s report, ‘excessive RT causes undesirable build-up of sound energy and results in poor speech intelligibility’, a situation that was far from ideal in an educational environment.
Davenport’s report recommended using Pyrotek’s echo-damping acoustic panelling to reduce the RT.
Pyrotek’s Bruce Hermes suggested the Echohush Cosmo line of acoustic panels with decorative slots that allow the acoustic cavity infill to absorb noise energy and control reverberation.
Bruce also recommended filling the ceiling girders with 100mm thick biosoluble fibreglass of 32kg/m³ density, faced both sides with Pyrotek’s white Sorberscreen.
In addition to meeting the functional acoustic performance requirements, Pyrotek was also able to customise the Echohush acoustic panels in the school’s colours to provide the aesthetic touch.
Satisfaction is high at the Umina Campus with the staff happy about the decreased levels of noise in the gymnasium and students reporting that they can now hear their teachers’ instructions.
Davenport’s follow-up report post-installation confirms a reduction of over 40 percent in the reverberation time in the empty gym, thanks to the installation of the Echohush panelling.
Echohush Cosmo is made from non-combustible materials, comprising of steel with fibreglass infill, making them suitable for institutions that must comply with strict fire codes.
Built robustly to meet rugged environments such as gymnasiums, the decorative acoustic panels are also available in a range of colours and sizes to suit individual needs.
