Acoustics Calculators

Acoustics Calculators

Acoustics calculators provide essential tools for students, researchers, and audio professionals to analyze sound propagation, wave behavior, and auditory phenomena. These calculators simplify complex acoustic formulas for sound speed, intensity, frequency relationships, and resonance conditions, making audio physics calculations accessible and efficient.

Use these interactive acoustics tools to calculate sound velocities in different media, intensity levels in decibels, Doppler shifts, beat frequencies, and resonant conditions in pipes and air columns. Each calculator implements standard acoustic physics formulas with educational clarity, helping you understand the mathematical relationships that govern sound waves and auditory perception.

Speed of Sound in Air

Approx: v = 331 + 0.6·T (m/s)

Speed of Sound in Medium

Formula: v = √(γRT/M)

Sound Intensity

I = P/A (W/m²)

Sound Level (dB)

L = 10 log₁₀(I/I₀), I₀ = 1e-12 W/m²

Beat Frequency

f_beat = |f₁ – f₂|

Doppler Shift (Sound)

f′ = f (v+vₒ)/(v−vₛ)

Pipe Fundamental (Closed at One End)

f₁ = v / (4L)

Pipe Fundamental (Open at Both Ends)

f₁ = v / (2L)

Sound Wavelength

λ = v/f

Resonance in Air Column

Open: fₙ = n v / 2L. Closed: fₙ = (2n−1) v / 4L
