Air Conditioner Hum 8 Hours
Continuous Window AC Drone for Overnight Sleep

A single window air-conditioning unit running steadily across the full night. The compressor hums at a low constant pitch, the fan cycles at a softer midrange drone, and a faint metallic rattle gives the sound the texture of a real unit in a real bedroom.
No click-on, no click-off, no thermostat cycles — the AC never stops. The combined drone lands squarely in brown-noise territory, masking traffic, voices, and bumps through shared walls.
The faint rattle keeps the signal feeling like a real machine rather than a synthesized loop, which most sleepers find more grounding. The level holds perfectly flat all night, so nothing thins out at 3 AM.
Perfect for people who sleep better in summer with the AC running, travelers missing their home bedroom sound, tinnitus sufferers, hot-climate sleepers, hotel regulars, and anyone nostalgic for childhood window-unit nights. Eight unbroken hours of air conditioner hum give you a familiar, reliable sleep environment anywhere you are. Press play, pull the covers up, and drift.
