Hello everyone!
First of all, thank you for the fantastic content Ethan and anyone contributing to the forum! A few years ago, with the help of your content and advice, I built my own bass traps for my living room made out of fibre glass and the results were stunning!
Now, after lying dormant for some time, I am trying to treat a heavy reverb sports gym room/hall that we use for table tennis training in our sports club.
The cellar room/hall is an elongated square with roughly 16 meters length by 8 meters width with 6m high walls. Walls and ceiling are made out of massive concrete or stone bricks.
The echo in this room Is INSANE. The background noise during training sessions is super intense given the high-pitched sounds of the balls and any human voices (table tennis balls made out of hard plastic on wooden tables hitting them at 60km/h and a frequency of 3-5 contacts a second on 4 tables in parallel).
Needless to say it’s not the bass we have issues with but the medium to higher frequencies.
Since I will be doing this with minimal budget out of my own pocket for our non profit sports club I was wondering what advice you might have for a cost effective solution?
Naturally I thought about absorption but since the room is so big I thought maybe diffusion would be an option as well?
But my gut feeling is that absorption by putting any kind of cheap high pitch absorption fabric/foam with 2-3 cm width on the 2 big parallel 16mx6m walls surface would already make a HUGE difference to significantly attenuate the parallel echo.
One issue of course that taken together the 2 long walls alone would be about 100m2 of surface area and that much fibre glass or rock wool would be super expensive. But then again, the room probably doesn’t need high quality 5-10cm thick rockwool to become sound dead, just dampened enough so talking and playing doesn’t feel so straining on the ears.
I attached a picture so you get a feel of the size of the room and it’s make-up.
I’m super grateful for any input and thank you already for your help!
Many thanks,
Ralf.
