It is a common phenomenon to observe that blowing over a glass beverage bottle produces a sound of a fairly definite frequency. The aim of this experiment was to see how well we could approximate glass bottles (such as that of a Sprite bottle) and a round bottom flask as ideal Helmholtz resonators in determining their fundamental frequencies and other associated harmonics. It was seen that though glass bottles are not Ideal Helmholtz Resonators, as they have no defined boundary between their neck and cavity, they can be assigned an average boundary level and then the approximation works to a fair degree of accuracy. In addition, a round bottom flask seems to, and can be approximated to a considerable degree, as an Ideal Helmholtz Resonator. | |
