Problems for the 30th IYPT 2017

Условие

A simple airhorn can be constructed by stretching a balloon over the opening of a small container or cup with a tube through the other end (see Figure). Blowing through a small hole in the side of the container can produce a sound. Investigate how relevant parameters affect the sound.

Sketch of the airhorn: a cup whose open end is covered by a stretched membrane, with a tube passing through the other end into the cup (dashed inside); a small blow hole in the side. Labels: Blow hole, Tube, Membrane, Cup.
