you are correct except for this. this is a subjective statement. what one person describes as twice as loud might not be twice as loud to another person.

Kinda true and very pointless.While there is a standardized pressure for 1 dB, in general, the way we use dB to describe SPL is a relative scale, where 1 dB is the thresold of human perception.
If you want to get technical, there is no way to quantify perception, so there is no way for a person to know if one sound is actually twice as loud as another(by perception alone).
If you want to get really technical, all perception is subjective.Take the color red for instance.We have been taught when we see light at a certain wavelength, its the color red.But red in your eyes is likely different from red in my eyes, since we are 2 different people with 2 different brains.Since I can never see with your eyes or hear with your ears, what I would describe as red, may not be exactly what you would describe as red.
So in general and for all practical purposes 10dB = 2x the perceived sound. |
