Partly because it is directional but more importantly due to proximity effect - which at close rage is dominant. Omnis have no such effect.



Proximity effect is a rise in low frequency response when the source is
close to the mic.

How does this reduce ambient noise?

Mostly it makes
the subject sound un-natural, ranging from god-like to muddy.


** Big over statement.

Close up, cardioid sound is warm and pleasing to most folk.

The cardioid effect does not apply to distant sound.



However, if the surrounding noise is objectionable when the subject is a
foot and a half away from the mic, moving the mic so that it's a few
inches from the subject's mouth will increase the SPL of the subject at
the mic substantially, however that change in mic position, unless the
subject is standing next to the cement mixer, will make a nearly
insignificant increase in SPL of the noise.

And miking up close, you
usually don't want the proximity effect bass boost,

Get you a big laugh.
