Question

please solve this
If the loudness is 36 find the amplitude ?

Answer 1

Explanation:

Loudness has a direct relationship with amplitude. Mathematically, it is proprotional to the square of amplitude.

Loudness = constant x (Amplitude)^2

L = constant x A2

A = L/constant

In given case, we are given that loudness is reduced by 36%.

L' = 0.36 L

L' = constant ( A') ^2

0.36L = constant ( A') ^2

Taking square root on both sides,

0.6 L/cconstan = A'

or

A' = 0.6 A

Hence amplitude will reduce by 60 %
