Q.No.160: - Will two separate 50dB sounds
together constitute a 100dB sound? Explain.
Ans: - No, two separate 50dB sounds together do not constitute a
100dB sound because dB is an exponential scale. Each ten dB increase in sound
makes the sound ten times louder. An increase of 50dB makes the sound 104
times louder. Hence it will not make 100dB but twice as loud is an increase of 10Log
(2) = 3.01dB. So 53.01dB is twice as loud as 50dB.
