"A sound event does not take place, but occupies a space. Even if the source often remains vague, its reception is wide and general. Vision provides a presence, sound does not. Sight distances us, music touches us, noise besieges us. Absent, ubiquitous, omnipresent sound envelopes bodies. The enemy can intercept radio transmissions but does not have access to our semaphore; sight remains unintrusive, sound waves will not be contained." Michel Serres
