T60 Reverberation Time Testing Question
T60 Reverberation Time Testing Question
(OP)
I am going to do a measurement on a larger space than I've tested before - where I've gotten by with a hand-clap - and I'm wondering if there are guidelines for the excitation sound level required? When can I use a large balloon (a friend uses a 36" dia. balloon), for example, and when would I need a gunshot or more? Obviously, balloons are easier to transport via air than pistols, but I have a range of firearms from the noisy to the horrendously noisy - e.g, 165+dB at 1 meter.
Is there a guideline based on the room volume and room constant?
Specifically, I'll be testing a space 25' x 29' x 19' high that initially is highly reverberant (T60 predicted 10.6 sec.), but then it will be treated to a predicted T60 time of 1.2 sec.
Thoughts?
Thanks,
R

It'll be fine.
If anyone's interested, I'll post a brief summary of how it turns out. We're using 2" Eckel panels for absorption, btw.
Thanks again,
