Primacoustic London 12a review - Part 2 - Acoustic Measurement - The DSP Project

Continuing on with part 2/2 of our review of the Primacoustic London 12a I decided to take some acoustic measurements to find out how much of a difference the panels actually made.

I'm curious as to what the dimensions of your room are. I'm guessing that the resonant frequency of the room is 35-40Hz given the amount of information that was lingering there. Have you plugged the room dimensions into a mode calculator?

[TheDSPproject]

@scu11ey Im no longer in that room but it was about 5x6m

Problem was it was an odd shape not a rectangle so those calculators dont apply.

Good idea all the same, thanks.

(thumbs up) really nice review there =D....btw could you tell me how you measured those graphs?

[TheDSPproject]

@xubxub Using an awesome program called fuzzmeasure, mac only. I have access to some expensive acoustic measurement hardware but still prefer this program!

@TheDSPproject First of thanks for making me buy more gear I just got my TC level pilot and my novation zero sl I love them both haha. I've been trying to figure out the best way to map it with Ableton, The standard mapping works well theirs just a few buttons and functions that aren't being used. Also What did you use to measure the waterfall graph and frequency response. Do you think an EQ would help much to get rid of some of those peaks?

[TheDSPproject]

@dylan3840 Ha ha your welcome, I used a great program called fuzzmeasure for the tests / graphs. You can use eq but there are a few issues. 1) the response will change around the room, making it worse in some places. 2) Putting everything through an EQ will colour the sound. So its not an option for me.

@TheDSPproject mostly smoke in the air i would guess, haha

[TheDSPproject]

@gix10000 I hope not too after I just finished putting them up! Might be moving to another place in London but a lot is in the air atm.

[gix10000]

@TheDSPproject its cool,

dont tell me you drilled holes in your landlords room and now you're going to move? haha

[TheDSPproject]

Thanks for the heads up @gix10000 its great having you around!

Yeah your right more traps would be next on my list. Not sure how long I will stay in this room tho so Im not going to spend any more just yet.
