Perfect / Recommended RT60 for studio control rooms?

Room Acoustics Forum by Rives Audio

Welcome! Need support, you got it. Or share you ideas and experiences.

Hi, i am am currently calculating the best RT60 times
possible for a control room which is 7m x 4.5m x 3.5m. I
have experimented with different materials etc. and
produced RT60 values for a range of frequencies which are:
125Hz 250Hz 500Hz 1KHz 2KHz 4KHz
the RT60 calculations i first calculated are as follows:
125Hz 250Hz 500Hz 1KHz 2KHz 4KHz
1.219 2.167 2.730 3.126 2.439 2.358
measured- reverberation time in seconds (s).
These values are obviously too high for that of a control
room and so added curtains.
By adding cotton curtains to half of the area of three
walls i ended up with:
125Hz 250Hz 500Hz 1KHz 2KHz 4KHz
1.082 0.901 0.817 0.573 0.656 0.758
These still being high values, from research i have found
that for the lower frequencies RT can be a little higher but
i am unsure as to what figure to aim for, to give me a
perfect or the 'recommended' RT60 for a studio control
room? I can change othewr materials etc and use diffusers
but am unsure as to how to go about it- e.g. if i was to
add a diffuers or another material to a wall do i edit the
area of what's left of that wall less that of the area of
the new material in the RT60 calculation for sabines?
I would be very greatful for your help.
Thankyou.
