Dynamic Microphone Placement for Voice
In this photo I am holding the microphone
about six inches from my mouth but not
pointing the microphone directly at my
mouth to minimize "popping" sounds
created by consonants "b", "p", "t" and
"d". People who speak softly may benefit
from pointing the microphone more
directly at themselves but still trying to
keep a little "off axis" by pointing it
between the nose and the mouth.
Dynamic microphones can accentuate the
bass frequencies especially when placed
very close to the mouth. There are ways to
avoid this "proximity effect" (see next
slide). I recommend a 80 Hz lo cut.
