Here's a specific room type I've never seen mentioned with regard to reverb: Medical exam rooms. Not surprising, and the issues there are similar to any other small room with a lot of hard surfaces. I was in one with my father the other day as a second pair of ears, since he wears hearing aids. Small exam room, hard walls and floor, "acoustic tile" drop ceiling, about 10x12x9. When the female nurse, who was young and with a pretty high-pitched voice, was speaking to us from about 5 feet away, the reverb was so pronounced that I had to repeat a lot of what she said to my father (my voice is fairly average 100hz-ish male voice). Hers must have been 250-300hz squeaky. I soon thought of you explaining reverb, and was thinking about how those empty wall spaces could be treated.
Concrete block is actually pretty good from 125Hz and up isn't it. No wait I was reading the wrong line. Good, because it didn't make sense that way. Are those pews fully upholstered or something like that?
Saw George Harrison at Oakland Coliseum Arena in the 70s and the reverb was so bad that the music was impossible to listen to. Guess we were supposed to be happy just being there. (Had to run the gauntlet of Krishnas outside.)
Informative and clear video!! 👍👌
Glad it was helpful!

Reverberation is the summation of all reflected energies from walls, floors, ceiling..
Hello, nice video
But why we need to focus only on 125hz - 500hz, Can u explain.?
This is the frequency range that has the largest impact on reverberation.

Concrete can actually absorb low frequency energies. Rememeber you are dealing with pressure waves of energy not ray energy.
great!
Thank you

I can't do large revues anymore due to high Rt-60 times.
Reverb destroys everything.
