Question

Relation between pressure amplitude and intensity of sound

Answer 1

Answer:

$The intensity of a sound wave is related to its amplitude squared by the following relationship: I=(Δp)22ρvw I = ( Δ p ) 2 2 ρ v w . Here Δp is thepressure variation or pressure amplitude (half the difference betweenthe maximum and minimum pressurein the sound wave) in units of pascals (Pa) or N/m2.$
