For a DJ is setting up their equipment and measures the sound level near a speaker to be 55.65dB, the new sound level is mathematically given as

L=50.470dB

What would they measure the new sound level to be?

Generally, the equation for the sound level is mathematically given as

l=10logl/io

Therefore

logl/io=5.57

Hence

I=3.715*10^−8

In conclusion

L'=10log(3*3.715*10^−8)/10^{-12}

L=50.470dB
