     Sound is all around us.  We hear it and we can feel it's vibrations, but we can't see it.  Like other forces, we have to use instruments and apparatus to determine its properties.  The Physics of Sound and sound waves is an exciting area for exploration.   We've provided lots of products for both grade school and college education.  Many great things for science fairs and science projects.

 

Science Kits
Demonstrate the principles and properties of sound.  Explore how sound is produced and transmitted.  Introduces the concepts of pitch, volume, and amplitude.  Investigate the physics behind sound energy.  Science experiments and activities include sound wave theory, reflection of sound, force of sound waves, sound transmission, vibrations and perception. 

 

Vibrations
There are two primary ways to explore the world of sound vibrations.  Start with tuning forks as they are the standard for exploring pitch.  That's why they are used to tune musical instruments.  The Sonometer utilizes a hollow wooden resonance chamber, same as the violin, bass, guitar and piano. It is used to verify the laws of vibrating strings, frequency comparison with vibrating bodes and determination of the frequency of a tuning fork by tuning a sting in union with it. 
Wave Analysis 1
Basic sound physics apparatus.  The Longitudinal Wave Demonstrator simulates the action of sound waves and demonstrates propagation, reflection, interference and a number of other resonant models of  longitudinal waves.  The flat coil spring and long slinky spring are used to visually demonstrate how sound waves work.. 
Wave Analysis 2
More advanced science apparatus.  The Kundt's Apparatus is used for demonstrating formation of stationary longitudinal waves in air or gasses and for determining the wavelength and velocity of sound in metal rods, aid and other gases. The Resonance Apparatus is used for experimental determination of the wave length and velocity of sound in air by locating resonance positions of an air column.  The Sound Wave Demonstrator is excellent for demonstrating the properties of sound such as frequency, amplitude, reflection, resonance, interference and diffraction.  The Ripple Tank
provides an excellent way to actually show the generation, propagation, reflection, interference and diffraction of sound waves.  Excellent for physics classes.
Speed of Sound Demonstrator
The electronics of this device allows student to accurately determine the speed of sound in air with a short distance (3 to 4 meters).  This helps reduce errors due to wind, noise, or attenuation.
