The screaming balloon: predicting the sound produced by a hex nut inside a balloon

In this work we studied the sound produced by the movement of a hex nut inside an air balloon. We demonstrated, by experiments with hex nuts and nuts without edges, the importance of the nut edges for the production of the screaming sound. Our experimental results show that the most intense frequenc...
