Particle displacement Guide, Meaning , Facts, Information and Description

Particle displacement or particle amplitude ξ in m is:

• acoustic impedance Z in N·s/m³
• sound velocity v in m/s
• frequency f in Hz
• sound pressure p in N/mē = Pa
• angular frequency ω = 2 · π · f
• particle velocity ξ in m/s²
• sound intensity J in W/m²
• sound energy density E or w in W·s/m³
• sound power or acoustic power P_ac in W
• area A in m²

Particle amplitude or particle displacement is a very important linear sound field value. You get it by measuring the sound pressure level and calculate it.
