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.

Hey buddy great review. I'd love to get some primacoustic panels but they're a bit out of my price range so I'm going for a UA Mercury 2 room kit. I'm gonna place the tiles at early reflection points to help tame the room. I'm intrigued by the measurements you took. Whats your opinion, is it worth it to get the flat response mic and fuzzmeasure? Would knowing the frequency response in the room improve tile placement etc? Thanks in advance

It depends on how geeky you are really. I would say no if your on a real budget you probably wont find a huge return as interesting as it is (to geeks like me). I would recommend you check out my studio monitor positioning video though as its free.

The 30-40hz that lingered with the old treatment wouldnt play a role in effecting the sounds that arent around that frequency area would it? And most speakers wont pick up that range anyway. Plus, Im guessing you're not likely to have that range in your recording. So if you don't have any sounds in that area playing back at you, does it matter if there is a long lingering in frequencies that don't exist in the first place? Not sure if I'm making sense, and please correct me if I'm wrong. thanks!

Most monitors can generate sound down there, even if its not loud / accurate enough to be included in the frequency response spec. Why would you not have that frequency in your recordings? A piano goes down to about 32hz. And in my case of electronic production its not uncommon to have a little something happening down at 20hz. This might sound crazy but some of the big club systems can get down very low. If I didnt use that part of the spectrum your right it wouldnt matter but I do.

ah, ok. thank's for clearing that out. I usually just filter out most stuff below 40hz. Good to know though, thanks

For sure, if you are working with say blue grass music with little going on that low you dont need to worry too much about treating that lower octave.

i think the waterfall graph looks really convincing. the highs have been improved as well from what i see.

Good video reviews man, well put together and informative. Nice work.... :)

[TheDSPproject]

The software is a program call Fuzzmeasure (very good but mac only). Then you need a measurement microphone (Has a flat response). The software plays special sounds through the speakers and listens to what comes into the mic, because the software knows exactly whats being sent to the speakers it can measure all the extra sound caused by the harmonics of the room.

Hope that makes sense.

I'm admitting I don't know about this. So saying that, how do you run these tests and then graph them like this?
