In 2014 the COSEE-TEK Team built upon the previous work and design concepts gained through alternative sources (see references below) to provide a vastly improved hydrophone design based upon the use of a piezoelectric microphone element. Using a simple setup with a plastic-covered dish (a model membrane) and candy sprinkles on top, students will create sound waves by humming and observe what happens to the sprinkles on top of the plastic. By measuring the sound levels coming from several different sources, you can determine which would be the noisiest items to have in and around your yard and what places would be the noisiest to live. Learn more about the physics of sound with these simple sound experiments. The shorter the bar the faster the vibration. Students will collect data from the model and organize it using grids and data tables by hand on paper and by computer with Excel.
