The sound level produced by one singer is 76.7 dB. What would be the sound level produced by a chorus of 41 such singers (all singing at the same intensity at approximately the same distance as the original singer)? Answer in units of dB.

In dB intensity will be equal to 159.74 dB

Explanation:

We have given intensity of sound produced by one singer is 76.7 dB

Sound intensity is calculated as

Now it is given that 41 singers are singing in chorus

So total intensity =

Now in dB intensity will be

i will answer your question if you answer mine

1.195000

explanation:

total mass=0.0117+0.0137+0.0881+0.0111

total mass= 0.01172kg

total velocity = 0.283-0.743+0.871-0.799+0.155+0.637+0.301=0.102

momentum=mv=0.1172*0.102=1.195000//
