Using feedback to set amplifier/loudspeaker volume to desired SPL

(1/1)

Ital-Rolando:
As stated by this article from Hyperphysics, the feedback (Larsen effect) is very close to a 1:1 ratio, so if you tune a microphone to a certain SPL and then trigger it at a certain point, you'll get that SPL at that point.

I made this video since I use this technique regularly for a couple of years now. I invite to make your own test and share your results.
