Graph Frequency vs. Note

Tuning forks are acoustic resonators in the form of a two-pronged fork with the prongs (tines) formed from a U-shaped bar of elastic metal. Tuning forks generate a relatively constant frequency that can be measured with sound analysis applications. The desired frequencies are printed on the tuning forks as seen in the photographs below.

Measure the frequencies of a series of tuning forks
- Enter your data here
- Copy the spreadsheet and produce a bar chart of frequency vs. note.
- Describe the relationship between note (pitch) and frequency

Collaborative Presentation

Provide screen captures of the following for three or more notes produced by tuning forks.
- waveforms
- sound spectrums
- frequency meter readouts
Exchange the graphics in the collaborative presentation with graphics you have obtained from the analyses you have been assigned.

Match Frequencies with your Voice

Each slide Tuning Fork slide in the collaborative presentation is followed by a "Voice" slide. Try to match each frequency with your voice and replace the graphics appropriately with graphs of your voice.
How does the sound quality of your voice differ from that of the tuning fork at corresponding frequencies?
