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

| Summary: | 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 frequency of the sound spectrum is directly proportional to the hex nut’s speed of translation, while inversely proportional to its lateral length, thus allowing one to predict the most intense frequency generated by this system. |
