Airbus A330 cabin noise in flight
The constant hum of a long-haul cabin: deep, steady, with no voices or announcements. It's one of the most popular sleep sounds, because it sounds like natural brown noise.
Why an ambient sound helps you relax
A steady, natural sound holds your attention without demanding it: the brain stops watching out for sudden noises and can let go. That's why rain, waves or a log fire feel so soothing, and why so many people sleep better on a train or a plane.
Headphones are ideal, but small speakers are fine. Keep the volume low: the sound should cover the noise, not drown it out. If noise makes you suffer day to day, talk to a doctor or an ENT specialist.
Questions
Why does airplane noise make you sleepy?
It's a deep, constant sound, close to brown noise: it covers outside noise and never surprises the ear.
Are there any announcements or voices?
No, the clip was chosen with no voices or announcements.
What is the best ambient sound for sleep?
Rain, ocean waves and airplane cabin noise are the most popular: steady, with no surprises. You can leave the sound on all night at a moderate volume; if you'd rather it faded out, set a timer.
Can I play two ambient sounds at once?
No, one at a time, so the sound stays clear. For a steady background, the white noise tool offers white, pink and brown noise.
Are the sounds royalty-free?
Yes. They are recordings their authors placed in the public domain (BigSoundBank, Freesound); the full list is on the sources page.
