25 minute timer with pink noise
Pink noise is white noise with the treble turned down. Each octave carries the same energy, which means the high frequencies are quieter and the result sounds like steady rain on a roof or wind moving through trees, without the sharp edge. Your browser generates it live, so there is no file, no buffering, and no loop point where the sound repeats. It runs alongside a 25-minute focus block, a 5-minute break, and a 15-minute break after every 4 pomodoros.
Pink noise is the middle option, and many people land on it after finding white noise too hissy and brown noise too muffled. It still masks conversation and keyboard clatter, but it sits further back in the room. Writers, coders, and anyone reading for long stretches often say it is the color they can forget about.
If what you need to cover is low and constant, like a fridge compressor, an air conditioner, or bass from the flat below, pink noise will not do much, and brown noise is the better tool. If your space is already quiet, try the silent timer first and add noise only once you catch yourself listening to the room.
Questions
what is the difference between pink noise and white noise
White noise has equal energy at every frequency, so it sounds bright and hissy. Pink noise drops by 3 decibels per octave, which quiets the treble and makes it sound deeper and softer, closer to rainfall or a waterfall.
is pink noise better than white noise for focus
There is no clear winner in the research, and preferences vary by person. Pink noise is easier on the ears over long sessions, which is a practical reason many people choose it. Run a few pomodoros with each and keep the one you noticed less.
can I leave pink noise running through the break
Yes. The noise keeps playing across the 5-minute break and the longer 15-minute one, so the room stays the same and there is nothing to restart when the next 25-minute block begins.
