Several questions. A condenser microphone works by forming a electrical condenser from the diaphragm and some other conductive surface. A condenser consists of two conductive plates with a insulator
Hello Everyone, What are the physical principles behind why are condenser microphones are adversely affected by high moisture? Is it a matter of humidity, condensation, moisture absorption, or some o
Hi umashankar and Scott-- Some questions sparked by your comments: (1) Audio Technica describes the AT-3032's element as, "fixed-charge back p= late permanently polarized condenser." I asked this bef

Hi Greg-- Since the moisture problems go away or greatly lessen when the mics are powered-up and outside, this is a significant _constant_ and one we can apply and base improvements on. Planning to s
uch. Seems like the strong trend for all types of noise to greatly diminish or disappear with continuous exposure over time would suggest that the "change" is happening on a small but significant sca
Thanks very much, Klas. You've improved my understanding considerably! Excuse me for raising my feeble question again: Over the course of the last 2.5 years of making recordings with several mic rigs
I used that mic in my homemade for over two years in Georgia. Lots of humidity and heat. I avoided getting rain on the mic or recorder, but did record in the rain some. One problem with a parabola is
Rob Danielson wrote some really good questions: (1) is this (AT3032) an electret mic capsule, not a "true" condenser? It's an electret capsule. I make no distinction between electret and non-e= lectr
wiki/Electret_microphone Thanks for helping me clear that up. But, if we assume that small electrets and then larger electrets are fundamentally more immune because of their design, its inconsistent

One potential solution to the moisture indicator is to turn on the power of your DAT machine an hour earlier, the internal heat from the preamps and electronics will usually evaporate the humidity. I
Been there with the D7 many times. No moisture issues I know of with the 722, 744 or HIMD for that matter in 100% humidity for days back to back. I know the 7XX's are being exposed to the humidity be

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

Briefly: "True" condensor microphones: A dc voltage, often 30 - 60 v , is applaid between a metalized membrane and a plate, electrode, often out of pure brass. (Corrosion??) The distance between the
All omnis are "sealed" between the membrane and electrode, but still... I mean, I have seen camera lenses with mould growing between two glued lenses. Double membrane cardioids are "sealed" too, but
