The relationship between ratio of the upper opening diameter read more of a cone-topped cylinder to the cylinder diameter,and the ratio of the length of the air column to resonant period was examined.Plastic cones with upper openings ranging from 1.3 cm to 3.6 cm and tuning forks with frequencies flexcon reverse osmosis water storage tank ranging from 261.

6 Hz to 523.3 Hz were used.The transition from a standing wave in a cylindrical column to a Helmholtz-type resonance in a resonant cavity with a narrow opening was observed.
