Old wall-mounted split AC running. Realistic mechanical “krrr-krrr-krrrr” rattling from the internal fan and loose plastic components, with an uneven compressor hum underneath. Occasional subtle vibration and clicking. Authentic aging household AC sound, slightly annoying and concerning, but not broken or catastrophic. No music, no voices, no ambience.

Wall-mounted split air conditioner running in a small quiet bedroom at night. Steady soft fan whoosh, low compressor hum, faint airflow hiss. Continuous, no changes, no people, no voices, no other sounds. Close room tone, slightly dull high end, indoor acoustics, loop.
