Helmholtz Resonator
![](local/data/caches/images/scaled/img_00028027_300x300.png)
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:
- Students will learn about the guitar/ukulele body as an acoustic resonator.
- Students will be introduced to the physics and math concepts of the Helmholtz resonator.
- 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.
- Students will apply the partial differential equation satisfied by the Helmholtz resonator to determine the instruments frequency.
