Settle in with 12 continuous hours of a Caterpillar CAT 15 diesel engine idling at a steady, consistent pace. This recording is designed for overnight use—providing a calm, uninterrupted background sound that many find helpful for sleep, relaxation, or focus.

The constant low-frequency engine hum creates a stable white-noise environment without sudden changes, voices, or transitions. Ideal for leaving on all night, whether you’re resting, working, or simply looking for a steady mechanical soundscape.

No talking. No music. No interruptions.
