🔊 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

💡 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
