mic for testing room

[gary h]

Hi all,

I am planning on testing my room using signalscope and a microphone. I have an Oktava MK-319 large diaphragm condensor mic that specs to 20 Hz. Will this mic be suitable?

Thanks,

gary

I might suggest carefully checking out the polar diagram of your mic ... how to aim the mic is easily as improtant as the response curve. ... And if your roll off at 20 Htz is not too bad, like 3 db down or less at 10 to 12 Htz, then no worry mate = its as good as it gets without lab equipment.

I'm not sure if you can use a cardioid mic...The one i use is omni:

For room measurements you should use omni. I like to use cardioid for speaker measurements sometimes though, to cut out the room influence a bit.

Tenson: a very good point = Omni directional for the whole room, directional (cardioid type) for individual speakers ...

(I have an old crystal mic (~/almost flat 10 to 24k Htz.) hooked to a very old BSR active eq-3000 for these kinds of measurements, and although the mic is supposed to be "omni", the reality is that all lower priced microphones are pretty directional.)

Hi,

As far as I know, it is generally the older 'omni' mics that are not so omni, not necessarily the cheap ones. A modern thing like the Behringer ECM8000 is pretty much as omni as any other.
