you are suggesting here. It sounds like you are saying that some mics have=

The problem with aircraft noise is that it doesn't just come from the sky. =
It arrives to our ears & microphones from all directions because we are in =
a diffuse field, meaning the volume of the reflected sound is equal to or g=
reater than the volume of the direct sound. In my experience there's only a=
marginal difference between aiming a cardioid mic away from or directly at=
a passing aircraft. Same with distant traffic, you get a few dB improvemen=
t at best by aiming away from the general direction of a highway. Having a =
big physical barrier, such as a hill, between you & that highway will do fa=
r more to attenuate traffic noise than merely aiming your mic the other way=
.
A directional microphone does not have a horizontal nor vertical orientatio=
n. It picks up equally well above & below the horizon as it does to the sid=
es. Also realize that adding a second directional mic makes the resulting s=
tereo array less directional than a single mic.
