🔊 Acoustic Impedance Calculator

Calculate acoustic impedance, reflection coefficient, and transmission coefficient

📐 Acoustic Impedance Formulas

Z = ρ × c
R = (Z₂ - Z₁) / (Z₂ + Z₁)
T = 2Z₁ / (Z₁ + Z₂)
Z = acoustic impedance, ρ = density, c = speed of sound, R = reflection coefficient, T = transmission coefficient
Acoustic Impedance: -
Reflection Coefficient: -
Transmission Coefficient: -
Power Reflection: -

💡 Tips & Information

  • Higher impedance difference = more reflection
  • Perfect impedance match = no reflection
  • Air-water interface reflects ~99.9% of sound
  • Temperature affects speed of sound in gases
  • Impedance matching reduces acoustic losses
