Check it out the following sites about Sound, or search Sound

» Acoustics and You - Find out about all the possible areas for a career in acoustics on this site by the Acoustical Society of America.
» Doppler Effect Activity - 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.
» Doppler Effect Demonstration - A Java Applet showing the how wave fronts cause the doppler effect.
» Doppler radar is a key forecasting tool - Find out how the doppler effect is used to read the weather, and how it can be used in short term weather prediction.
» How Ultrasound Works - Learn about how waves are reflected as they travel through various objects, and how these reflections are used to produce images for medical use.
» Longitudinal Wave Activity - See how the particles move, and the graphs for acceleration, velocity and displacement when the sound frequency is changed in this activity.
» Musical Acoustics - 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 .
» Radio Transmission - Learn about the different stages of radio transmission, how radio waves are emitted, and the difference between AM and FM radio.
» Science of Sound - 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.
» Sound - Elucidates traveling and standing waves using diagrams to show harmonic and overtone wave patterns.
» Sound Waves and the Eardrum - 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.
» Sound is Energy - 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.
» Sound, Light and Radio Waves - Frequency, amplitude and wavelength effect waves of sound, radio, light in different ways. Changing one of these characteristics affects the others.
» Sounds and Noise - Try these experiments which show the physics of sound waves by using objects around the house to demonstrate how they travel.
» Standing Sound Waves - Uses diagrams to show pressure nodes and internodes of harmonics in a pipe.
» The Doppler Effect and Sonic Booms - Explore in detail the wave front diagrams of stationary and moving sources at both subsonic and supersonic velocities.
» The Physics Classroom - 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.
» The Physics of Sound - Uses graphs to explain production and perception of sound.
» The vOICe Sonification Applet - Draw your own Sound - Explore synthetic sound and vision with this voice mapping java applet. Sonify the premade images, or make your own.
» Waves Lecture - Power point slides covering wave speed and pulses, energy, superposition, standing waves, doppler effect, Huygen's principle, refraction, interference, and diffraction gratings.
