The mic features a unidirectional cardioid polar pattern, which is the best natural defense against room noise: since the capsule mostly captures what’s directly in front of it, you won’t pick up as much room noise as you would with another polar pattern. Depending on your particular room, you may still need a little room treatment, or some noise-reduction software, to address issues such as your computer’s hum or your air conditioner—but the chances of that are markedly lower with a cardioid polar pattern.
