Re: Damping floor/ceiling room node?


I'm pretty sure. Node charts for my size room show a floor/ceiling node at 73Hz, and I have a null at around 70Hz that moves with height. Will panels anywhere help, or is there some preferred position to kill the node? I was hoping the 1st reflection damping would also help kill the node.

Maybe a helmholzt absorber tuned to my exact problem frequency should be considered too? Since it's a specific frequency. A 70-something box wouldn't have to be excessively big.
