has anyone ever thought or tried having a Jecklin disk like thing as a baffle underneath their mics? to block/ diffuse crowd noise? I'm relatively tall and tape mostly with mics clipped to a brim of baseball cap and to me it seems like the brim deadens the sound of shorter people around me compared to when if I need to clip the mics lower like to a shirt collar. SO I'm thinking you could mount a Jecklin disk underneath the mics on a stand and achieve much the same results. I realize this probably has a negative effect on some polar patterns (maybe all ?) but if you are in a chatty environment and raise the mics to the roof for some reason or another would this technique work?

A Jecklin disc is meant to give separation between channels, like your head does between your ears. Using one to mute talkers will also mute that part of the sound that is occupied by the talkers. I do not stealth, but stands can be raised to get above the talkers, with the exception of omni mics, although would help to an extent. There is very little you can do about people in front of you, but the only problems I have from behind are things like bottles breaking in a bin, for example, with cards and I rarely run over 7' - 8'.

I record from stage lip a lot, where sometimes mic placement can be tricky because of stage monitors, and have often wished I had some method to block or minimize the sound from the monitor(s.)

It will work, somewhat, the same way it works between the two omni in a Jecklin setup and makes them directional at higher frequencies. It will only reduce the level of higher frequency direct sound picked up from sources which are obscured from a direct line of sight to the mics. It will not block the lower frequencies, or the reflected or reverberant components of those sources. The primary practical problems are that it's unwieldy and unfriendly to sight-lines.
