The proximity effect is often an issue when you record guitars (the E-string is is around 80 Hz). So it’s an important factor when you record male voices, especially in the lower range, but it’s of less consequence for female voices. Obviously, the proximity effect is most noticeable on sounds with a lot of low frequency content below 200 Hz. You can use it to make things big, fat, and sexy, but you have to keep it in check for a good overall balance and maximum transparency. So the proximity effect is a friend and an enemy at the same time. However, the proximity effect can also compromise speech intelligibility and make the low-end sound muddy, when “fattened” vocals and guitars get in the way of bass and kick drum. The proximity effect is what helps DJs on the radio to sound like Barry White, and many a singer would sound like the skinny kid he is, if it weren’t for the blessings of the proximity effect.
