Sound Wave Physics Simulators

Add two sine tones whose frequencies f1 and f2 differ slightly and a slow loudness pulsation appears at |f1 - f2| Hz, the classic beat phenomenon.

Visualize standing wave patterns in a tube. Adjust frequency, tube length, and boundary conditions to explore resonance frequencies and pressure distributions in real ti…

Calculate acoustic impedance, reflection/transmission coefficients, and loss instantly. Visualize wave behavior with animated diagrams for any two-medium interface.

Explore standing wave resonance in open pipes, closed pipes, and Helmholtz resonators. Adjust pipe length, temperature, and harmonic number to see how flutes, clarinets,…

Visualize acoustic standing waves in tubes. Interactive simulator shows mode shapes, natural frequencies, and formulas for open, closed, and half-open resonators.

Visualize the Doppler Effect in real-time. See sound waves compress and stretch, calculate observed frequency, and experience shock waves as a source moves.

Adjust source velocity, observer velocity, and speed of sound to calculate observed frequency in real time. Three tabs — circular wavefront animation, frequency-velocity…

Set delay time and temperature to calculate reflection distance

Helmholtz resonator simulator: real-time resonant frequency, effective neck length, wavelength and period from cavity volume, neck diameter, neck length and sound speed.

Set a reference sound level, source distance and number of sources to compute SPL, distance attenuation and combined level. Compare with everyday reference sounds.

Calculate combined sound pressure levels, distance attenuation, and A-weighting corrections for noise analysis. Compare results with WHO/ISO standards.

Visualize sound waves in real time. Adjust frequency, waveform, and amplitude. See particle oscillation animations and hear the resulting sound simultaneously.

Compute the speed of sound c, target speed at Mach M, Mach cone half-angle and 1 km travel time in real time from heat capacity ratio gamma, molar mass M, temperature T,…

Visualize string eigenmodes in real time. Compute fundamental frequency and harmonics from tension, density, and length with this wave simulator.

See how much energy a medical ultrasound pulse loses to absorption and scattering as it travels through tissue.

A real-time calculator for the active and passive sonar equations (Urick 1983).
