Problem: People are listening to music too loud through headphones and it is making permanent damage to peoples ear.
Target: Commuters. Due to the sound of the transport people naturally turn up their headphone volume. They are unaware of the extreme damage it can cause if you listen to music at 100% volume for more than 15 minutes a day.
Solution: Using a series of posters as well as interactive billboards and tube carriages make people aware of the cause.
With the use of Shazam - Commuters music would be recognised and displayed for the whole platform or train to see. Causing the listener to be embarrassed and raise awareness to the cause that they are listening to thier music too loud!
