For the most part, the folks selling Chinese microphones get the data sheet
numbers from the factories. None of the factories have what I would consider
reasonable test equipment and none of them have a real chamber as far as I
can tell except BSWA.
MANY of the factories are selling microphones whose designs they got from
somewhere else. Along with them, they provide specs that came from the
factory whose design they are duplicating.
Most of the Shanghai-style mikes, for instance, quote a 9 dBA noise floor,
with no information on how that was measured. I cannot IMAGINE any of
these mikes ever coming anywhere near that low.
