Sonic Lab Specs
THE SONIC LABORATORY
The Sonic Laboratory is a unique multi-functional concert hall / research laboratory. It can accommodate an audience of up to 150 and features a 48-channel sound diffusion system with large projection screen.
1.1 The Structure
The lab measures 17m L x 13m W x 14m H. Audiences and researchers enter the lab at ground floor level and walk out onto an acoustically transparent, modular grid floor suspended 4m above the structural floor of the lab located at lower ground floor level. Approximately 7m above the audience area is a technical gantry spanning the perimeter of the lab and nine motorised ceiling panels which can be independently lowered to ground floor level. The ceiling panels are rectangular aluminium box trusses (2m x 1m) from which loudspeakers, stage lights and/or microphones can be suspended.
The lab can be configured for a wide range of acoustic responses e.g. at 1kHz the reverberation time of the space can be made to vary from 0.4 – 2.3 seconds. This is achieved through a series of 48 acoustic absorbers which can be raised or lowered to expose or cover each of the walls. There are two mechanical pulley systems per wall and each pulley controls 6 absorbers. Finally a series of theatre black style curtains span the perimeter of both the technical gantry and the lower ground floor allowing for sections of theses walls to be covered or exposed as required.
1.2 Sound Diffusion
The stage lighting system for the Lab is all LED powered and consists of an Avolites Titan Mobile console controlling 6 x Robe Robin moving head lights, 18 x Chauvet Slim Par Pro LED Pars and 8 x Chauvet SlimPar 56 Pars.
There is also total of 102 15A dimmers are available in the Lab - 6 per ceiling panel, 16 at ground floor level, 16 at technical gantry level and 12 at lower ground floor level.
A large 7 meter-wide retractable acoustically-permeable screen is installed at the front of the lab. A Panasonic PT-RZ970 laser projector provides high definition video from multiple input sources including a Blu Ray player, HDMI and VGA connections.
1.4 Impulse Responses
By raising and lowering the acoustic absorbers in the Sonic Lab reverberation times between 0.4 - 2.3 seconds can be achieved. Some impulse recordings of the space can be downloaded below.
Recordings are made using a DPA4006 microphone at 96kHz
