From an RT60 standpoint (really more for larger rooms but OK for reference), you'd want to be around 200ms in the midrange - maybe 250 in the lows and 160-170ms in the high end. You're really more interested in RT30 which is a bit more than 1/2 of those times but most people don't like it that dead.

Untreated, the low end is now probably closer to 1 second or a bit more.

Thanks Bryan

I will measure on Saturday morning but I will probably need guidence if that is ok

I will post the results on here.

Just one more thing, how do you cut rockwool into triangles?

Regards
Marty

No problem.


Here is the cut pattern to turn 2'x4' sheets into 8 17x17x24" Triangles.



Use a sharp disposable razor knife to keep the blade sharp. 703 is more expensive but a lot easier to cut and work with.

703?
Razor Knife?

Sorry

Over here I know in our D.I.Y. store Wickes or B&Q they sell rockwool in rolls 50mm thick, not sure where to get sheets from?

I assume a razor knife would be the same as our retractable stanley knives?

Pretty much the same thing. These would be disposable and have break off blades. Very thin blades, plastic housing, etc.

For sheets, look at an insulation supply house or a metal building insulation company.

Re: When is room treatment needed

Marty, I haven't used the newer version of REW yet, (Maybe this week...) but I believe you can view the waterfall graph for any measurements you have already taken and saved to disk. In the older version You could reopen them and select the waterfall tab to generate the graph. I thought I would mention that so you didn't think you had to set up all the gear and remeasure just to see the decay times for your current situation.
