The Sound You Cannot See
Across eight tasks, listen to original tone clips and solve text puzzles to work out what a sound traveled through, which path change altered it, and how far an echo went.
All clips are original synthetic tones, and each puzzle supplies its own simplified legend, so the answers come from the rules shown. Every audio task has a text transcript for a no-audio route. This is not a hearing test.
Your choices are summarized at the end, and any tasks with right answers are checked separately. Progress is kept in this browser only so you can resume.
