Effects of Spheres on Helmholtz Resonance by adjutis is a document available to read on EtoBox.
1. A Helmholtz resonator was filled with spheres of different sizes and materials to determine the effect on resonant frequency. Resonant frequency measurements were made for different fill levels of spheres and compared to measurements made when filling with water. 2. It was found that the resonant frequency was higher when filled with water compared to spheres at the same fill height, indicating the air pockets between spheres affect frequency. Additionally, the resonant frequency peaked at a critical o
