The Sound-Sweep

In JG Ballard’s ‘The Sound-Sweep’,[1] the sonic strata of everyday urban life – a ‘frenzied hypermanic babel of jostling horns, shrilling tyres, plunging brakes and engines’[2] – is so without respite that it is literally embedded within walls and surfaces and must be vacuumed away with a device called the ‘sonovac’. The central character, Mangon, is a mute who has developed hyperacute hearing, making him a valued sound- sweep. His main client is Madame Gioconda, an ex-opera singer whose career ended with the advent of ‘ultrasonic music’. Ultrasonic producers electronically rescore classical symphonies into musical notation that operates on a subliminal level, making use of the sensorium beyond the normal range of the human ear. Supposedly the new music, ostensibly silent, has richer texture, theme and emotion, but whether this is merely a placebo effect to placate the frazzled masses remains ambiguous. Mangon strives to resurrect Gioconda’s career, but when he does eventually stage her comeback, she botches it, her voice so cracked, out of practice and out of tune that it causes great distress to all who hear it. The story ends with Mangon driving off in his sound truck as he turns on the vehicle’s inbuilt sonovac – filled with the city’s sonic detritus – to drown out Gioconda singing like an ‘insane banshee’. Effectively, Mangon manipulates the sounds of the city to assuage his psychological turmoil.[1]
