Umeå Institute alum Ru Zarin made these Audio Ties:

Creating a wireless audio level meter and deploying it at an event or function where there is a DJ and lots of people.

Each tie is associated with a specific level in the Audio Spectrum and moves in real-time in relation to the music at the venue.

The tie’s are completely wireless using a radio transmitter to get the signal from the DJ source. This gives the tie’s a range of up to 1 mile (pending obstacles).

Each tie is powered by an ordinary 9V battery, giving the wearer the ability to move freely throughout the venue with the technology hanging around their neck.
