Sines, and cosines, and tangents, oh my...sines, and cosines, and tangents, oh my...sines, and... )
digitaltec said:while on the topic of dB, here's a fun little FYI from a light guy:
For the human ear to hear a difference in volume, you must increase the dB by 3.
So, if you are using 2 speakers and want to gain 3dB you would go to 4. then if you wanted to gain 3 dB again, you would go to 8. if you want to gain 3 dB again, then you would go to 16. Thats why at concerts, you would easily have 40 speakers per side.
