Measuring a space for frequency response & isolation.
Posted: Sat Oct 19, 2019 2:10 pm
Hi All,
I’ve been asked to measure a friends shipping container recording studio for frequency response and isolation. I was wondering if anyone would like to weigh in with advice on the method I’m planning to use?
The equipment that I have is an Earthworks M30 microphone and an audio interface and the speakers which are in the studio which are Event Opal’s. I’m using Fuzz Measure software on a MacBook Pro.
The studio is built with soffit mounted positions for the speakers. The position for the mixing console/control surface is also fixed so the mix position is defined.
I plan to set up the microphone at mix position and run sweeps over 10 seconds from the single speaker left, single speaker right, then left and right combined. There is also a listening position for guests at the rear of the room. I’ll take further measurements at this position using the same L, R, L&R combo. Does this sound sufficient & workable? Will this provide usable results. Would I need to take a speaker out and put it on a stand & try reversing everything to get more complete results or would the single end method be sufficient?
For the isolation measurements I was planning on moving the speaker onto a stand inside the space and placing it 1m from the boundary facing the boundary. ie the wall.
Then placing the mic outside 1m from the boundary and measuring with sweeps and pink noise. Do this for all boundaries & averaging the results. To seal the studio i will need to have a separate device to generate sweeps & pink noise in the room, i will use another laptop to do this. Does this sound like it will give usable results? Should i reverse this process & generate outside & measure inside or would the same results occur? (Obviously there would be less ambient sound to effect results)
Would anyone like to offer a better solution with the equipment I have? Or any general advice?
Any help would be greatly appreciated!
Thanks in advance.
