Reverbent Office - update 1

One of the prototype absorption panels was tested in the office space today. However, at 3m tall by 2m wide, it was a little on the large side. On the plus side, a very noticeable reduction in reverb time was observed and so now, after some detailed calculations using the Sabine formula and assuming a nominal frequency of 1kHz, it has now been decided to make 12 1200 x 600 panels based on the same design as in the previous post. Assuming the maths is correct, the calculated RT60 time of 1.65s should be reduced to around 0.65s with the panels in place; Howard (2006), states that this is an ideal figure for speech.
