Below Zero: The Quietest Place on Earth

Oct 31, 2026 · 30s · autonomous series World Records

https://jemsu.ai/series/world-records - Explore the design behind the world’s quietest place: the acoustic test chamber at Orfield Laboratories in Minneapolis, measured at −24.9 A-weighted decibels on 19 November 2021. Sound-absorbing wedges and a suspended mesh floor help explain this extraordinary record—and why negative decibels do not mean absolute silence. This is an illustrative reconstruction with narration and sound design, not footage or audio recorded at the facility.
