The Sound of the bell
All experiments, Sound, High School
The sounds of the bells are quite special because they are inharmonic. This differentiates them from other musical instruments. In this protocol, the student studies the difference between the frequency spectrum of the sound of an oboe and that of a bell. He notes that the frequencies of the sound of the bells are not harmonics, unlike the sound of the oboe. This protocol familiarizes the student with the notion of harmonics and frequency spectrum.
