-Proximity effect is when a directional microphone's frequency response changes based on how near or how far the sound source is from the transducer.  It occurs due to the design of the housing within the microphone and the additional air pressure that occurs when sound is reflected from the back of the housing back towards the diaphragm adding more lows or low/mids to the overall signal.
+===== Proximity Effect =====
+Proximity effect is when the frequency response of a directional microphone (i.e. [[polar_pattern|cardioid]] or [[polar_pattern|hyper cardioid]]) changes based on how close the sound source is from the microphone.  This change occurs due to the housing design of the microphone. As the sound source (such as a vocalist) moves closer to the microphone the sound waves reflect off of the back housing into the diaphragm resulting in increased lows and low/mids.
-In addition to the proximity effect, as the sound source moves closer or further away, the inverse square law applies to all frequencies.
+The proximity effect is more pronounced on sound sources having more low or low/mid frequencies to start with (e.g. Male Vocals vs Female Vocals). This translates artistically to more bass or power in the vocal. The proximity effect is what makes Barry White sound like Barry White.
-This has the most effect on sound sources that have alot of low or low/mid frequencies in them.  In other words it will be more noticeable on a male vocal as opposed to a female vocal.
+In addition to the proximity effect, as the sound source moves closer or further away, the [[inverse_square_law|inverse square law]] applies to all frequencies.
-It translates artistically essentially as more bass or power in the vocal fundamental frequency.  The proximity effect is what makes Barry White sound like Barry White.
