Find out about all the possible areas for a career in acoustics on this site by the Acoustical Society of America.

This shockwave activity shows the way that waves originate from a single moving source, and provides a link to the same activity using two sources.

A Java Applet showing the how wave fronts cause the doppler effect.

Find out how the doppler effect is used to read the weather, and how it can be used in short term weather prediction.

Learn about how waves are reflected as they travel through various objects, and how these reflections are used to produce images for medical use.

See how the particles move, and the graphs for acceleration, velocity and displacement when the sound frequency is changed in this activity.

Detailed look at how sound can be analyzed with a microphone and oscilloscope with clear examples of expected results.

Learn about acoustics of different instruments, the sound spectrum, standing wave patterns supported by different air columns on this page by The University of New South Wales, Australia .

Learn about the different stages of radio transmission, how radio waves are emitted, and the difference between AM and FM radio.

A partnership site between the Science Museum and the Minnesota Orchestra, exploring the science and art of sound by offering performance, activities, and discussion sections.

Find out about sound waves, and how their graph varies with change of pitch and volume. Check out the experiments which show that sounds are vibrations.

Offers an animation of how high and low pressure waves make the eardrum vibrate along with information on how the journey of sound waves affects the brain.

Frequency, amplitude and wavelength effect waves of sound, radio, light in different ways. Changing one of these characteristics affects the others.

Learn all about sounds and waves through a graphical-learning based interface in four lessons.

Try these experiments which show the physics of sound waves by using objects around the house to demonstrate how they travel.

Uses diagrams to show pressure nodes and internodes of harmonics in a pipe.

Explore in detail the wave front diagrams of stationary and moving sources at both subsonic and supersonic velocities.

The sound section of a more diverse site. Contains lots of information and fully explained diagrams. Check your understanding with a quiz at the end.

Uses graphs to explain production and perception of sound.

Explore synthetic sound and vision with this voice mapping java applet. Sonify the premade images, or make your own.

Power point slides covering wave speed and pulses, energy, superposition, standing waves, doppler effect, Huygen's principle, refraction, interference, and diffraction gratings.
