GOALS

Physics

• Study three-dimensional acoustic resonance with acoustic transducers in a rectangular box.
• Determine the proper placement of transducers for efficient coupling.

Technique

• After doing preliminary calculations, place miniature speakers in the positions to induce and measure the resonant field.

Errors

• Compare actual measured resonant frequencies to calculated resonanaces.

Questions (Work out in lab book before coming to class)

1. What effect would there be on the frequencies of a rectangular cavity missing one wall?
2. What effect would there be if individual walls were replaced with sound absorbent material?
