Use this interactive echo simulator to change the distance to a wall, air temperature, and reflecting surface, then observe the outgoing sound and its returning reflection. How to use the echo simulator 1 Choose the distance Move the distance slider to place the reflecting wall from 1 to 100 metres away. 2 Set the air … Read more
Use this standing wave visualizer to select harmonics, adjust the wave, identify nodes and antinodes, and hear the corresponding tone. How to use the standing wave visualizer 1 Choose a harmonic Select a button from 1 through 6. The string pattern and the node, antinode, and tone readouts update immediately. 2 Adjust the controls Change … Read more
Explore the superposition of waves by changing the frequency, amplitude, and phase of two waves, then observing how their displacements combine to form a resultant wave. How to use the superposition of waves tool The explorer displays Wave A, Wave B, and their resultant in three aligned graphs. Begin with a quick experiment or build … Read more
Explore the human hearing range from low bass to very high frequencies, compare pitch and period, and optionally record observations from short quiet tone bursts. How to use the human hearing range explorer 1 Lower your volume Set your device volume very low before playing a tone. Stop immediately if any sound feels uncomfortable. 2 … Read more
Enter any two known parameters such as mass and volume, volume and density or mass and density to find the third unknown parameter Density Calculator Density (g/cm³): Mass (g): Volume (cm³): Calculate
Make your own sound wave by choosing a waveform, changing its frequency and amplitude, adding multiple waves together, observing the shape, optionally listening to the resulting tone, and using your microphone to investigate real sounds. How to make your own sound wave The visualizer opens silently. You can explore every control and waveform before starting … Read more
