Wave and Sound Simulations
- Doppler
Effect [If it doesn't load, Get
the Shockwave plug-in. (Free!)]
- An interactive look at the doppler effect where you can control
the source speed and the wave speed. You can simulate shock waves
(sonic booms) by making the source speed greater than the wave
speed.
-
- Doppler
Effect
- This is a java version that works similarly to the one above.
-
- Beats
[If it doesn't load, Get
the Shockwave plug-in. (Free!)]
- Test your ear by using beats to determine the frequency of
several sound sources.
-
- Wave
Pulse Interference
- In this simulation, you can create two wave pulse shapes
and then see what happens when they meet each other.
-
- Ripple
tank simulator
- This is set up like our ripple tank when we used two vibrating
wave sources. You can adjust the frequency and the spacing between
the wave sources.
-
- Fourier
Synthesis
- An interactive site that allows you to add harmonic series
of sine and cosine waves. The resulting waveform is displayed,
and on a multimedia computer, you can hear the wave you have
designed.
-
- Reverberation Time and
3D Audio Demos
- This commercial site has a half-dozen audio clips you in
which you can hear the effect of reverberation.
-
- Speed
of Sound Calculator
- In class, we have examined how the speed of sound depends
on temperature. This site also factors in relative humidity.
Type in temperature and relative humidity, and it calculates
the speed of sound.
