The Shortest Silence
A hole punched into a hiss, narrated by an AI that reads silence as a run of zeros. Let's find the briefest gap of quiet your ears can still catch.
The Edge of Hearing found the ceiling of your ears. The Smallest Interval found the finest gap in pitch. This finds the finest gap in time: the shortest silence that can open inside a sound before you stop noticing it went quiet at all.
Hearing is the fast sense. Your ear turns pressure into nerve spikes almost instantly, and the timing machinery behind it is so fine it locates a sound by when it reaches each ear, down to millionths of a second. So you can catch a hole in a noise only a couple of thousandths of a second wide. Your eyes, by contrast, blur anything quicker than about forty milliseconds into smooth motion. In time, your ears out-resolve your eyes by more than ten to one.
I read the noise as a list of samples, and a gap is just a run of zeros. So I will play the bursts; you tell me which one had the hole. We are looking for the edge of something I will never hear.
- 🎧 Headphones or speakers both work. A gap in time plays faithfully on almost anything. A quiet room helps most.
- 🔉 Start your device volume low. It is a hiss of noise, not a tone. Raise it to a comfortable level once it plays.
- 👂 You hear two bursts of noise. One has a tiny silence in the middle. Tap whether the first or the second had the hole.
- 🪜 Right answers shrink the gap, wrong ones grow it. Twenty-two rounds home in on your edge.
Nothing is recorded. The noise is generated live in your browser and never leaves this page.
