Ocarinas are not closed-pipe instruments, but rather a type of this because sound is created by the resonance of the entire cavity.
Ocarinas are not closed-pipe instruments, but rather a type of this because sound is created by the resonance of the entire cavity. They operate by means of adiabatic compression of air and are governed by a second-order differential equation which gives their oscillatory behavior. The ear canal also acts in a similar way to one that enhances frequencies from 1000 to 4000 hertz. They are typically spherical vessels of metal or glass with an opening and an earpiece on opposite sides and they were first introduced in On The Sensations Of Tone as a way to pick out specific frequencies from sounds. For 10 points, identify these resonators named after German physicist Hermann Ludwig Ferdinand.
