Got my mic and measured the room. But I would appreciate any opinion before I start doing anything.
Doesn’t seem to be any major issues with excessive decay/echo, in fact everything above 40hz is under 300ms. Main issue is a couple of big dips. they correspond with speaker placement and mic placement. This is about as smooth as I have been able to get in this room through positioning, and now I want to focus on reflections and bass – I think?
All dips and peaks are under 20db - i think they are tameable with treatment and maybe a little eq.
I am thinking;
- If the dips are narrow enough, do i need to stress. or just eq as best i can and accept that the room in my house isnt perfect? eg green one at 200hz
- Do I focus on reflections first, then see what issues remain and then tackle them? Eg could absorption help the issue at 70. Is this issue worth spending lots of effort/$$ on?
i have a small budget to DIY some treatment, but i want as much confidence as possible before investing.
Would anyone have any guidance on what next for this room? Eg Limp Membrane bass traps or acoustic absorption and then traditional bass traps?
Here’s my measurement results.
No smoothing.
1/6 smoothed up to 10khz
No smoothing, 2 different speaker positions. No point showing all measurements, just on wall and off wall shows these dips relate to speaker position.This 36hz dip is related to speaker or amp warm up. After a few hours of playing music i retried and no dip at all. Nothing else changed. My speakers low freq spec is 39hz, so i wont worry about this too much for now.
RT60 Pink is Optimal and Green is Actual.
My room is totally untreated.
Book cases line the left hand wall floor to ceiling.
