Want to stop losing friends in the lighting department?
Rarely do we have ample time to tune a PA. Since we require a “quiet” room and will be making “loud noises”, the entire load-in can come to a halt. We’ve got to get our measurement rig up in a hurry, move with a purpose, and get things done.
To make matters worse (I have been guilty of this in the past), we blast pink noise at near show levels while taking measurements.
Today I want to ask the question…is this necessary? Let’s dig into a little measurement theory and find out, shall we?
Today we’ll cover:
- Your biggest ally when assessing the quality of measurement data
- Should you shoot for a target SPL or some other metric?
- Why in the world we all use pink noise as our test signal
