Is the idea that it prevents the sound from going beyond the mic and then reflecting off the wall facing the singer, to then rattle around in the room?
They certainly absorb some of the sound and reduce the amount of energy going out into the room, but not a particularly significant amount in my experience. The main benefit is in preventing some of those reflections reaching the rear and rear sides of the mic -- and in the case of a cardioid mic, those regions are still surprisingly sensitive. ONly the absolute 180 degree rear null offers any substantial 'deafness'. Most cardioids are only 6dB down at the 90 degree point, and rarely more than 15dB down across much of the rear.
Thank you for that, Hugh!
Being a newbie in many more ways than not, I went to my AT 4033a spec sheet ( http://www.vadlyd.dk/addinfo/AT4033a.pdf ), and saw that it was labelled "cardioid". But on inspecting the polar diagram, it looked like the best place for "deafness" was at around -45 degree "behind the horizontal", rather than the "180 degree rear" (where it looked like it was fairly sensitive, especially at 8kHz).
Can you please help me figure out where my interpretation of the polar diagram is wrong, based on your statement above?
Thanks so much, as always!
