refrigerator hum
Appliance background noise
Refrigerator hum is the low, steady drone produced by a refrigerator's compressor and motor—a background noise so constant it typically goes unnoticed until it stops.
The phrase often represents ambient sound that fades into unconscious awareness: The only sound was the refrigerator hum from the kitchen.
Writers use it to evoke domestic quiet or late-night stillness.
