(a) Find the dB sound level heard by someone at a Justin Bieber concert standing 3.00 m away from an 80.0 W speaker.(b) Find the dB sound level if the person is standing 3.00 m away from two 80.0 W speakers. (c) Besides having poor taste in music, how else is this person exhibiting poor judgment?

ANS = 118.5 dB, 121.5 dB

Expert Solution

ansr c - due to increase in intensity by two time the sound level increase by 3db (121.5db-118.5db) . But this increase of sound level is independent of original sound level . Therefore the person exhibit poor judgement .

Thank u
