I’m sitting in a café on Saint-Brieuc’s main street, with a plan to enjoy the usual background buzz and get a bit of work done. Coffee on tap, notebook out.
But instead of the comforting hum of conversation, I’ve landed in the middle of three separate phone calls being shouted from three separate street corners:
Each one is a half-conversation. Each one is loud. Together? They’re impossible to ignore.
And so instead of cracking on with some thinking, I’m sitting here, pen hovering, wondering: why is this kind of noise so hard to work in, when a proper café clatter actually helps?
There’s a name for that buzz you crave: “distracted focus” and it’s the optimal state for working on creative tasks.
Researchers have found that the sweet spot for focused work is somewhere around 50 to 70 decibels: the volume of a busy café or the sound of light rain. It’s a steady flow of sound, not too quiet, not too intrusive.
That sort of background hum helps your brain switch into abstract thinking and creative problem-solving.
But when someone starts a phone call nearby - and especially when several people do - our brains can’t help but try to complete the conversation. It’s not just noise anymore. It’s a puzzle, and your brain’s trying to solve it.
That’s why this morning’s coffee shop felt so different: not all distractions are equal.
If you’re working in a school or designing learning spaces, think about this:
Do your quiet areas feel quiet? Or are they full of half-conversations and foot traffic?
Are your collaboration zones deliberately noisy? Or just loud?
The right kind of background sound can actually make people more focused. But the wrong kind - fragmented, jarring, inconsistent - will pull focus faster than you can say, “sorry, what was I doing?”
