Thanks for getting Doug in Dave, Might be a 101, but I'm gonna feel like I have a degree on mics by the end of this series. Great stuff.

It is amazing the detail these videos get into.

Dave, these series of videos are GREAT. Better than reading from a book, much more informative, so anyway great stuff and keep them coming!

Wonderful lectures. Doug reminds me of my old very much admired lecture. Old but very knowledgeable. Step by step and enthused into the topic. wonderful! Valve old analogue still rules. Thanks Dave.

Dave, thanks for doing these videos, I'm sure they don't get as many views as say mailbag Monday but they have a value in their own right. Just as your videos on Op-map theory.

Curious as to if there were other materials used for the diaphragm before the age of plastics, or did this design arise only after? If so, were the only designs preceding it of the ribbon and carbon-impregnated capsule variety that Doug mentioned in the introductory video #602? EEVblog

How about Noise, I just got a mic in and it humms like hell. Its a Electret SE1000A, had the same problem with the older version SE1000. I thought I could bias it with a 10k Trim Pott? Any one have a cure for this?

What kind of microphone would you need to record elephants who are known to communicate with infra-sound (sub 10 Hz )?  Every microphone I've ever heard of dies a horrible death at low frequencies.  Would you be in pressure transducer range and would you need multiple microphones to get a high fidelity wide range recording?
