Title: Do LDC's attenuate less with distance than SDC's?
Post by: connloyalist on March 17, 2014, 07:09:57 AM

I would appreciate some education on something. Somewhere I read something to the affect that an SDC will attenuate more with distance from a sound source than an LDC will. In other words, if you get the same level out of an SDC and an LDC at distance X then moving to distance 2X or 3X the level of the SDC will be less than the LDC. All this of course assuming the same polar pattern. 

Correct, grain of truth or bunk?

Bunk.

In addition to the polar pattern being identical, the sensitivity would also need to be the same.  Differences in sensitivity between the two microphones will make the largest differences in output level regardless of polar pattern.

Thank you for clearing that up for me  :)
