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.

So, what is 2x 100db?
103db
and 3x 50db?
10log(2)=3.01.so 53.01dB??????
So what would 6000 @ 75db equate to?
i dont understand solve it with example
kindly give the answer by solution.
No it will not make 100db because the decible scale is a logarithmic measure of the amplitude of sound waves. In a logarithmic scale,equal intervals correspond to multiplying by 10 instead of adding equal amounts
