Pyrotek Noise Control
was commissioned by the Australia Capital Territory Law Courts to improve the acoustics of the Magistrates Courtroom.
Poor clarity of sound, in particular speech due to a high level of reverberation not only caused a problem for the seated audience but also degraded the quality of court recordings.
Prior to the installation of the acoustic solution, Pyrotek conducted an impulse response test to measure the level of reverberation within the courtroom. The Magistrate’s court recorded a time of 1.4 seconds against an ideal range of 0.4 to 0.8 seconds. The exceptionally high reverberation time was traced to the hard interior walls that reflected sound around the courtroom, causing the clarity of sound and speech to be indistinct.
Pyrotek’s solution to resolve the acoustic issues involved installing a number of fabric-faced and timber panels from the Echohush range onto the walls and ceiling in an attempt to absorb the echoes overpowering the room. Approximately 50m² of absorbing panels were installed in the courtroom.
Reverberation time measured in the courtroom following the installation of the acoustic panels has significantly reduced to 0.5 seconds, allowing better acoustic performance. Speech in the room now has greater clarity, allowing both the magistrate and the court monitors to carry out proceedings in a more efficient manner. Magistrates are able to hear parties in question clearly without disruption from reflecting echoes.
The Echohush decorative panels combine acoustics with aesthetics, achieving significant noise control to enhance courtroom procedures while enriching room aesthetics.
Pleased with the result, the ACT Law Courts commissioned Pyrotek to soundproof a second courtroom.
