The sounds
The Sounds tab groups the library into rain, ocean, water, wind, fire, night, noise, travel, home, tones, ambient and melodies. The library is more than 45 sounds and tones. Every sound is loop-tested. Free sounds are marked in the table.
| Group | Sounds |
|---|---|
| Rain | Soft (free), heavy, window, tent, metal roof, distant thunder, heavy storm. |
| Ocean | Distant (free) and waves. |
| Water | Stream and waterfall. |
| Wind | Light (free) and trees. |
| Night | Fireplace, crickets and night forest. |
| Travel | Plane cabin (free), train, car, ship. |
| Home | Washing machine, tumble dryer, dishwasher, fridge. |
| Fans | Low, deep, box, whisper. |
| Noise | White, pink, green, soft brown (free), dark brown, cabin hum. |
| Ambient and melodies | Four ambient pads, a heartbeat, a cat purr, lullaby and drift melodies. |
| Tones | Five tones, including 432 Hz (free). The Drift generator is free. A frequency you dial in yourself is Premium. |
The tone generator is for relaxation only. It makes no medical or healing-frequency claim. Two-tone presets play a slightly different tone in each ear, so headphones are the better way to hear them, kept low.
Plane, fan and white noise
A plane cabin is a steady, low drone, the hum of an aeroplane, in the same family as brown noise. Beside it sit a train, a car and a ship. At home, the fans are low, deep, box and whisper, with a washing machine, a tumble dryer, a dishwasher and a fridge. White noise is the bright hiss. Pink, green, soft brown, dark brown and cabin hum tilt darker, and a deep fan or a tumble dryer leans towards brown. A recording adds a little motor texture that a pure hiss does not have.
Why that helps, and how loud is too loud, is in fan and appliance noise for sleep and white, pink and brown noise. Using the travel drones on a journey is in sleeping on a plane or train.
Mixing, timers and the screen off
The free tier plays one layer at a time. Premium unlocks five layers, each with its own volume, and unlimited saved mixes. A plane cabin can sit under a quiet fan, or brown noise under rain. You can rename a saved mix. Timers are 15, 30, 45 or 60 minutes. When the timer ends, the sound fades over 30 seconds up to 3 minutes, rather than stopping dead. The longer fades are Premium. Playback continues with the screen off.
Whether to leave a sound on all night or let it fade is covered in sleep sounds all night or with a timer.
What you can try first
TritonSleep is free to download. The free tier includes soft rain, distant ocean, light wind, soft brown noise, the plane cabin, a 432 Hz tone and the Drift generator. Premium unlocks the rest of the library. Premium is €0.99 a month or €9.99 a year in Ireland. There is no account, and the files are in the app, so a cabin sound still plays in flight mode.
Frequently asked questions
Does TritonSleep have a plane cabin sound?
Yes. Travel sounds include a plane cabin at cruise, a train carriage, a car on the motorway and a ship's cabin. They are stored on the phone, so they play in flight mode.
Are there fan sounds for sleep?
Yes. The fans are low, deep, box and whisper. They sit with a washing machine, a tumble dryer, a dishwasher and a fridge.
Is there white noise?
Yes. White, pink, green, soft brown, dark brown and cabin hum are in the library. Soft brown noise is free. White is the bright hiss. Dark brown is the deep rumble, closer to a cabin or a large fan.
Can I mix a plane cabin with a fan?
Premium mixes up to five layers, so a plane cabin can sit under a quiet fan. The free tier plays one sound at a time. A mix you like can be saved and renamed.
Will the sound stop when the phone locks?
No. Audio keeps playing with the screen off. A timer of 15 to 60 minutes can fade it out, from 30 seconds up to 3 minutes, instead of cutting it off.
Do the sounds need an account or a signal?
No. There is no account, and the sounds are stored in the app rather than streamed. They play with no signal.
