From the jangle of an alarm clock to the din of downtown, the film assembles overwhelming and sometimes amusing evidence of noise pollution as an environmental scourge demanding a halt.

Noise pollution as apocalypse is almost too on-the-nose for a 1972 polemic, but Henson's refusal to let the argument breathe—just *relentless* accumulation—has a punk energy that makes the sermon feel genuinely unhinged.
A formally rigorous essay film that locates itself squarely in the structural documentary lineage; the assembly of sound as argument, the darkly comic tone threading through institutional critique—this is how you make a manifesto that doesn't date.
The real move here is the *restraint* in the visuals—Henson lets the audio do the overwhelming work, which on a 1972 budget means every image placement becomes a decision that either echoes or punctures the soundtrack's mounting chaos.
