Helmholtz Resonator

This 5-page resource, from the STEM Guitar Project, is an activity on acoustic resonance. "... this activity will explore how the hollow body of a guitar/ukulele works as an acoustic resonator, as well as what these instruments have in common with the Helmholtz resonator. This activity has the following objectives:

1. Students will learn about the guitar/ukulele body as an acoustic resonator.
2. Students will be introduced to the physics and math concepts of the Helmholtz resonator.
3. Students will measure and calculate the volume of the body of an acoustic instrument (irregular shape) and the radius and area of the sound hole.
4. Students will apply the partial differential equation satisfied by the Helmholtz resonator to determine the instruments frequency.
