But, no! -3dB is half power, not half loudness. -3dB down is just slightly less loud.

- globular-toast 1y agoExactly. There's no way +3dB is perceptibly twice as loud. That's easy to test for yourself. +10dB is roughly twice as loud.
- creeble 1y agoThe BBC used to teach +6dB for twice as loud for music sources, but they've always been a bit conservative.
- kazinator 1y ago+10dB is twice of something: it is an increase in loudness which is twice compared to a +5 dB increase. If +10dB is absolutely twice as loud, it means that 110 dB is 32 times as loud as 60 dB. We are then essentially denying that perception of loudness is logarithmic!
