Coffee shop sounds
A busy café without the words: a dozen distant voices murmuring in a warm room, cups set down, spoons on saucers, and now and then the milk steamer. Nobody is saying anything you can follow.

Why café noise can help you work
A 2012 study by Mehta, Zhu and Cheema (Journal of Consumer Research) found that a moderate level of ambient noise, about 70 dB, improved performance on creative tasks compared with a quiet 50 dB room, while loud noise (85 dB) hurt it. Their explanation is that moderate noise adds a little difficulty, which nudges you towards more abstract thinking.
The effect was for creative tasks. For reading or memorising, many people do better with steady noise, so keep the café low or mix it with brown noise.
How our café is made (no recordings)
Every voice is synthesised. Eleven virtual talkers, each with their own pitch, distance and seat, speak in phrases of wordless syllables: a buzzy voice source shaped by real vowel resonances (formants), with pauses between phrases. Distant talkers are duller and quieter, and a short room reverb blends them. Speech without words stays a murmur, so it does not pull your attention the way an overheard conversation does.
On top are cup and spoon clinks built from inharmonic ringing partials, soft thuds of cups set on tables, one far-off milk steamer per cycle, and a low ventilation hum for the room.
Questions
Do coffee shop sounds help you study?
They can for creative work. Mehta et al. (2012) found moderate café-level noise improved creative thinking, but loud noise did not. For reading-heavy work, keep it quiet or add brown noise.
Can I hear what people are saying?
No. The voices are synthesised syllables with real vowel sounds but no words, so the chatter cannot be followed.
How loud should café sounds be?
The study's sweet spot was a moderate level, about as loud as a normal conversation nearby. Above that, performance dropped.
Can I make a rainy café?
Yes. Try the Café Study preset on the home page, or raise Rain alongside the café here.
Is this a recording from a real coffee shop?
No. Nothing is recorded; every sound is generated in your browser, so there are no real people in it and it never loops the same way twice.
