This work allows for the sonorisation of the exhaustion of a 9V battery.
A circuit connected to a speaker transforms the electric frequency into the corresponding sound frequency. What comes out of it is an extremely high-pitched, penetrating, nearly annoying sound, capable to pierce the space, make its way like a trap into the listener’s ears.
The intensity of the timbre is bound to lose strength, to weaken little by little, remaining in the thoughts just like the vibration of a fleeing memento mori.
