I have a pair of mics that claim Equivalent Noise Level of 5dB-A.
Another mic claims 70dB Signal to noise ratio. How can I compare
the noisiness of the two mics?
Hook them up to two channels of a preamp, bundle them up in a pile of
pillows, put them in a quiet place, then listen to them. If you want to
be studious about it, record the noise and look at it with a spectrum
analyzer program. If you're going to do that, be sure to check the noise
of the preamp first, with its input terminated with a nice quiet 150 ohm
resistor.
