Sir, pls clarify my doubt. U told that absorption coefficient of the wall will become 1 as there is no reflection of sound, but while writing the power equation why didn't put A=1??
We're caluculating not only for wall here but deriving the formula for all materials, so to determine the power lost or dissipation we can take a as 1 as you said for wall
I think there is something wrong in the derivation sir because log 10^-6 is not equal to -13.8 as shown in your video. This is giving me a different value instead of 0.163.
