Acoustic Properties

Absorption coefficients for typical installation using standard flat stretched materials with minimum 50mm thermal insulation above.

frequency (Hz)	63	125	250	500	1000	2000	4000
Absorption Coefficient	0.1	0.5	0.47	0.57	0.44	0.23	0.17

Coefficients averaged from ISO354(1985) reverberation room tests for various mounting configurations & should be used as a design guide only

Example Reverberation reduction for typical hard surfaced & carpeted room of 3m x 4m x 2.65: - Mid frequency reverberation before stretched ceiling: 1 sec Mid frequency reverberation AFTER stretched ceiling: 0.4sec
