Wind Chimes Project Details
Goal: Build two sets of wind chimes from hollow tubes:
- One that sounds a chord in a Western musical scale.
- One that sounds a chord in a non-Western musical scale.
Resources: We have the following materials that you may find helpful:
- Tuning forks - produce reference sounds of known frequency.
- Microphones that input sound through a LabQuest into the computer for analysis using the LoggerPro software.
- Visual Analyzer program for easily measuring frequencies.
- Audacity program...it's a sweet program but I don't know how helpful it'll be for this application.
- Electrical conduit for making tubes.
- Learn to use the LabQuest and/or Computer to measure the fundamental frequencies of tuning forks.
- Perform the following experiments and record what you found in your blog:
- Experiment with a sample chime to find the fundamental frequency of a chime.
- Experiment with a sample chime to find out how the quality of its sound depends on where you hold it.
- Experiment with a sample chime to find out how the quality of its sound depends on where you strike it.
- Experiment to find how the fundamental frequency of your chime depends on its length.
- Investigate the relationship between length and frequency on two other sound producers. Is it always the same or does it depend on the instrument? Instruments to consider checking would be:
- The WMC band's chimes
- Guitar, violin, or piano strings
- A pipe organ
Weeks 3, 4, and 5
- Build your two sets of wind chimes. Take pictures of each step in the process and include them in your notebook or blog.
- If doing a blog, prepare a podcast of your chimes playing. If not, turn them in for Mr. Falk to listen to.
- Find one expert on sound somewhere in Western Michigan. Have them write a review of the quality of your chime.
