Arrays of water jets as user interfaces: detection and estimation of flow by listening to turbulence signatures using hydrophones

ABSTRACT

The hydraulophone is a fun-to-play self-cleaning keyboard instrument in which each key is a water jet. Many hydraulophones are already equipped with an array of underwater microphones (hydrophones), to pick up the turbulent sound from water inside musical sounding mechanisms under each water jet. Accordingly, we propose to make greater use of the sound of the water flow.

We propose to extract more detailed information about flow and the obstruction of flow, based on sound alone. Beyond musical instruments, if further developed, this framework could have extensive applications in flow sensing for fuel lines in vehicles and for fresh water lines in buildings.
