Question

How to calculate the amplitude of sound of n object

Answer 1

The Amplitude is the height from the center line to the peak (or to the trough). Or we can measure the height from highest to lowest points and divide that by 2.

...

Example: 3 sin(100t + 1)

amplitude is A = 3.

period is 2π/100 = 0.02 π

phase shift is C = 0.01 (to the left)

vertical shift is D = 0.
