Too many hard-reflective surfaces and little sound absorption caused both spaces to suffer from excessive reverberation leading to poor communication conditions. The main office had a mid-frequency reverberation time of 1.8s and the meeting room 1.2s. as a guide, for general offices, the target reverberation time is 1.0s and for audio-visual, video conference rooms it is 0.8s.
Sound absorption was needed to be added to both spaces with the client insisting that the solution should not alter the decorative and visual look of the spaces.
dBA specified twelve 40mm thick sound absorbent, hanging wall and ceiling tiles to be installed throughout both spaces.
