= Proximity effect (audio)
{wiki=Proximity_effect_(audio)}
The proximity effect in audio refers to the increase in low-frequency response that occurs when a sound source is positioned very close to a directional microphone, typically a cardioid or hypercardioid microphone. This phenomenon results in a boost in bass frequencies as the microphone captures more low-end sound due to its polar pattern, which is designed to be sensitive to sound coming from the front while rejecting sound from the sides and rear.
