Room reverb time, and why it's important
It's important to know the reverb time of the room you are working in. The reverb time can make speach difficult if not impossible to understand. Below are some Reverb calculators, and some basic training modules... but credit is given where credit is due... I didn't author most of this information, just compiled it and directed you to it...Below please find a good explanation of reverb time, and what affects it...

Remember that 2k is the critical vocal clarity value. If the 2kHz reverberation time values are greater than the target values shown below, you will likely have a speech intelligibility problem. These are the 2kHz target values for reverberation time for each of these applications.
* Classroom for hearing impaired accessibility 0.5 seconds
* Church or theatre for speech/amplified music 1.0 seconds
* Church or theatre for traditional music 1.5 - 1.8 seconds
* Meeting Rooms 0.6 - 0.8 seconds
* Large Convention facility 1.5 seconds
* Gymnasium for teaching 1.5 - 1.8 seconds
* Industrial Buildings 2.0 - 2.5 seconds
* Small arena (500 -2000 seats) 2.0 seconds
* Large arena (2000+ seats) 2.75 seconds
Check out these primers, they will help you understand acoustical analysis...

This will prime you for your task... check out the various reverb times...this is REALLY COOL!

I may add more to this, and you can respond to it in the regular forum as it was DRA that sparked this discussion...It will be important to know this stuff if you wish to tame a church or gym, but that is yet another discussion...
Oh, and by the way...you too could have found out ALL this information for yourself because all I did was do searches, and compile the pertinent information for you...
