Graph Frequency vs. Note
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
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
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?
