Measurements of impulses produced by bursting balloons are presented. Various sizes of
balloons were popped with a mechanical device in an anechoic chamber and recorded with
a spherical microphone array. The power responses and directivity of the balloons are
analyzed. Results indicate that power responses have two emphasized frequencies which
depend on balloon size and inflation level. Larger balloons radiated more energy and
higher inflation levels resulted in stronger high frequency content. Balloon directivity patterns …
