Question

Approximately how many times louder is a 145-dB sound than a 85-dB sound?

Answer 1

Hi Emma L.,

you could have searched "dB vs. perceived loudness"??

+10 dB change corresponds to a doubling of perceived loudness.

(That's NOT the same as sound energy; +3 dB change there corresponds to a doubling of acoustic energy.)

You can figure out the delta and apply the appropriate 2^n conversion?
