This is from the awesome recording thread:

Where these are most useful in the studio is in creating the right sense volume, space, and size that will fool the ear on playback. In other words, we can make gunshots *sound* deafening, even at perfectly safe listening levels, within limits.
Facts about the rock band AC/DC that you might not have known:
-The singer from AC/DC usually sings whisper-quiet.
-The guitar players from AC/DC usually use quite low gain settings for heavy rock guitar, older Marshall amps with the knobs turned up about halfway (no distortion pedals).
Both of these fly in the face of impressions that most casual listeners would have about AC/DC, which is a band that has been releasing some of the loudest-sounding records in rock for decades. The reality is that the moderate amp gain settings actually sound louder and bigger than super high-gain settings, which are prone to sound nasal and shrill at low volumes.
The singer, like TV gunshots, is creating the impression of loudness without straining his voice by only pushing and exerting the upper harmonics that are strained while screaming. IOW, he's singing not from the diaphragm, as most vocal coaches teach, but from the throat and sinuses. Instead of screaming, he's skipping the vocal chord damage, and only exercising the parts of the voice that are *unique* to the scream. He's using parts of the voice that normally never get used except when we're screaming our head off, and the result is that it sounds like someone screaming his head off, even though he's barely whispering. Because nobody walks around talking like that, the effect is of a "super-scream," something that sounds louder than any mortal human could ever scream, because the normal sound of a human voice is completely overwhelmed by the effects that are usually only heard during screaming.
My point is not to endorse AC/DC, nor to say that you should try to emulate them, only to cite a commonly-heard example as a way to illustrate how perceived loudness, size, and impact can be crafted as a studio or performance illusion.
