Thunderstorm sounds: rain with distant thunder

Do thunderstorm sounds help you sleep

Thunderstorm sounds help some people fall asleep, but no study has tested them for sleep or relaxation in people. The only research on thunder sounds concerns dogs and their fear of storms. Everything a page like this can say about thunder at night comes from nearby research: studies of natural sounds, and studies of how sudden noises disturb sleep.

Those two bodies of research pull in opposite directions. The rain under the thunder is a steady natural sound, the kind that research links with lower stress and with fewer disturbances from other noises. The thunder itself is the opposite of steady: a sound that rises out of the background, lasts a few seconds and fades. That is exactly the shape of the noises that wake sleepers.

So the honest answer depends on you. If a storm makes you feel sheltered and drowsy, distant thunder kept low can be part of a good bedtime. If you are a light sleeper, rain alone is the safer choice.

Why do people find thunderstorms relaxing

People often describe storm sounds as cosy: the feeling of being warm and dry inside while weather rages outside. That feeling is common and easy to recognise, but it has not been studied. What has been studied points to two ingredients of a storm sound that listeners tend to like.

The first is the rain. Natural sounds, and water sounds among them, were linked with lower stress and better mood in a 2021 meta-analysis of 18 studies in the Proceedings of the National Academy of Sciences (Buxton and colleagues); thunder is not among the sounds that meta-analysis names. The second is the low rumble. The thunder in this generator is built from brown noise, and in listener ratings of more than 1,300 people (Færøvik and colleagues, Frontiers in Neuroscience, 2025) brown noise was rated the most "sublime" of three noise colours, while white noise felt the most uneasy.

Neither finding is about real thunder. Together they explain why a soft, low, far-away rumble over rain can feel pleasant rather than alarming, as long as it stays soft and far away.

Can thunder sounds wake you up

Thunder sounds can wake you up if they are loud relative to the rain beneath them, because sleepers react to sudden jumps in sound more than to loudness itself. In a small sleep-lab study (Stanchina and colleagues, Sleep Medicine, 2005), recorded intensive-care noise raised arousals from 13.3 to 48.4 per hour. The number of arousals depended on the jump from the background level to the peak of each noise, about 17.5 dB, not on the peak level. When white noise raised the background, the same noises produced smaller jumps and arousals fell back to 15.7 per hour.

A careful 2026 study (Basner and colleagues, Sleep) showed what intermittent noise does over whole nights. Twenty-five healthy adults slept seven nights each in a laboratory with full sleep recording. Traffic-type noise events of 45 to 65 dBA reduced deep sleep, the N3 stage. Thunder was not tested, but a rumble that swells every half minute is an intermittent noise event of the same kind.

The conclusion is practical: the rain should be the steady floor and the thunder only a little above it. The smaller the gap between them, the less likely the thunder is to wake you.

How often does the thunder roll in this generator

The thunder here rolls at a random moment every 15 to 45 seconds and each roll lasts between 4 and 10 seconds. It rises over half a second to a second, swells and dips a few times, then fades away while its pitch sinks, the way far thunder grumbles down to nothing. There is no sharp crack: a close lightning strike is the most startling sound a storm makes, and it was left out on purpose.

Under the thunder, a light rain plays at a quarter of its normal strength. It gives the storm its steady floor. On its own the thunder layer would be long stretches of near silence broken by rumbles, which is the least sleep-friendly shape a sound can have.

How loud should thunderstorm sounds be for sleep

Thunderstorm sounds for sleep should be quiet enough that the loudest roll stays below the level of a disturbing noise. The World Health Organization's Guidelines for Community Noise (1999) recommend that continuous noise inside a bedroom stay below about 30 dB and that single noise events not exceed 45 dB. A thunder roll is a single event, so its peak is what counts.

Set it in three steps, lying in bed with the lights off:

• Start with rain alone and set it to the lowest level that covers the sounds of the house and street.
• Add the thunder layer at about half the rain's volume and wait for two or three rolls.
• If any roll makes you open your eyes or notice your heartbeat, lower the thunder, not the rain. You want the rumble to feel like it is in the next valley, not over the roof.

Keep the speaker away from the bed. Low rumbles travel through furniture and floors, and a phone lying on the mattress carries them straight to you.

Thunderstorm sounds with a timer: fall asleep, then silence

Thunderstorm sounds are best used with a timer, so that they help you fall asleep and then fade out before the deeper part of the night. Of all the sounds on the mixer, thunder has the strongest reason for a timer, because its irregular peaks are what the research above links with disturbed sleep.

Research on steady noise gives another reason. A systematic review of 38 studies (Riedy and colleagues, Sleep Medicine Reviews, 2021) rated the evidence that continuous noise improves sleep as very low quality and warned that noise may also disturb sleep and hearing.

The timer fades the whole mix out over its last minute, so the end of the storm does not wake you.

Rain and thunder sounds: mixes for a rainy night

The classic storm mix is steady rain with distant thunder, and the ready rainy night mix here plays rain at 70 % with thunder at 50 %. The mixer above combines seven noise colours and seven nature sounds, each with its own volume, and has a timer from 15 minutes to 8 hours that fades out over the last minute.

Some variations:

• Rain, thunder and brown noise: the brown noise fills the low range, so the thunder stands out less. The most sleep-friendly storm.
• Rain, thunder and wind: a wilder storm for reading or relaxing on the sofa.
• Thunder, rain and fire: a storm heard from beside a fireplace; for evenings, since the crackle is uneven.
• Thunder and stream: rain that has already run into a brook, with thunder going away.
• Rain alone after the first hour: start with the full storm, then switch to rain for the rest of the night.

The rain sounds page covers rain on its own, including how it compares with white and brown noise.

Thunderstorm sounds for relaxation, reading and work

Thunderstorm sounds are easier to enjoy during the day than at night, because an occasional rumble matters little when you are awake. People use a storm mix to read, to write, to make a grey afternoon feel deliberate rather than dull, or as a short break with eyes closed.

For relaxation after a stressful day, the research on natural sounds offers a modest reason to try it. In a Swedish experiment (Alvarsson and colleagues, 2010), 40 people who had just done a stressful arithmetic task recovered somewhat faster, measured by skin conductance, when they listened to nature sounds than to noisy environments. That study used nature sounds in general, not storms. For work, keep the thunder low: a roll that makes you look up breaks concentration just as it breaks sleep.

When thunderstorm sounds are a bad idea

Thunderstorm sounds are a poor choice whenever the listener is afraid of storms or sleeps lightly. A sound that you find cosy may make a child, a partner or a dog tense. Studies of storm fear exist only for dogs, but the practical point needs no study: if a real storm makes someone in the house anxious, a recorded or generated one will not make them sleep better.

• Babies and small children: use a steady sound instead. The white noise for babies page explains the advice on distance, volume and timer.
• Light sleepers and people who wake at every small noise: choose rain without thunder, or steady brown noise.
• Shared bedrooms: agree on it first; the other person hears every roll too.
• Pets that fear storms: do not play thunder where they sleep.
• Anyone with a real storm outside: the generator cannot mask real thunder, which is far louder.

Generated thunderstorm vs a real storm recording

A real thunderstorm recording is richer but less predictable than a generated storm, and at night predictability matters. Field recordings of storms often include a close strike: a crack that arrives with no warning at many times the level of the rain. In a long video or an eight-hour track you cannot know when it comes.

The generated storm has only distant thunder, with a soft rise and a fading tail, at a level you set once. It will never surprise you with a crack, an advertisement or a sudden change of track. What it gives up is the drama of a real storm, and for sleep that is the part worth giving up.
