(1) Amplitude (A) of vibration of the source ,

I∝A

2

,

(2) Surface area (a) of vibrating body ,

I∝a ,

(3) Distance (r) of listener from the source ,

I∝r ,

(4) Frequency (f) of the source ,

I∝f ,

(5) Density (ρ) of the medium ,

I∝ρ ,

(6) Motion of the medium , which changes the effective speed of sound .
