Experiment
DL10 Quality of Sound and Harmonics
|
| Objectives |
- Study the pattern of sound from a musical instrument by recording the sound in the Scope display of a data-logger
- Learn to use the advanced tool in analyzing the frequency components of a musical note
- Appreciate the pure note produced by a tuning fork
- Study the relative amplitudes of harmonics of a music note
