Re: Physics of moisture-induced mic noise

<<Just for reference, in my experience AKG C451 can have problems with
humidity/moisture even in studio/indoor recording senarios (e.g.
perspiration from drummer has caused the mics to pop when used as
overheads, which is a shame as they sound great as overheads).>>

Wow, that's a new one on me. I've used 451's for at least 30 years &  
not had that occur. I will say, the contact point between capsule &  
preamp is very susceptible to minute amounts of tarnish or corrosion,  
requiring a vigorous cleaning of both sides of the contact with steel  
wool about once a year. It is a great drum overhead mic, although in  
almost all cases now my Neumann KM84's get that assignment.
