🎵 Hear Your Ears Work

An interactive essay, not a record: Bartosz Ciechanowski’s Sound hands you little keyboards from the first screen and builds everything you hear from air molecules up. Headphones on, an unhurried evening, volume set sensibly before you touch anything.

  1. The arc runs molecules to reverb without skipping steps. Colliding air spheres, pressure in a squeezed box, a plate that pops, triangle waves with amplitude and phase, sine from a rotating circle, strings you pluck with the mouse, decibels from a slider, Doppler from a moving speaker. One continuous climb, each demo earning the next.

  2. The move I keep coming back to is drawing. Sketch any waveform with your finger and hear its timbre instantly, then watch the decomposer rebuild your shape from 64 sine waves. Fourier in both directions, ten seconds apart. The square wave’s Gibbs ripples shrinking as high sines join is the kind of thing textbooks describe and nobody believes until they drag the slider themselves.

  3. The honesty is engineered in. Phases that cancel to silence, beats from near-identical frequencies, the admission that pressure colors lie about minuscule variations, the 0.02-pascal whisper that still moves your eardrum. Every demo that could mislead carries its own correction.

  4. Edges: it wants JavaScript, WebAudio, and your full attention, not background play. The microphone spectrum demo is optional. Budget an hour. You will not finish it in one sitting and that is fine; the sections stand alone.

Start here: the essay is the instrument, so these fixed videos are its footnotes. Slow-motion strings and cymbals showing the modes, plus the two-speaker dead spots you can walk through at home.
