Quietest Place on Earth is too Quiet You can Hear Your own Organs

Picture an environment of profound silence, where even the faintest whisper of sound is conspicuously absent. In this sensory vacuum, one can intimately perceive the symphony of their own body – the steady drumbeat of their heart, the rhythmic expansion and contraction of their lungs, and the gentle gurgling of their digestive processes. This level of quietness is exceptionally rare, inviting introspection and a unique connection with one’s internal rhythms. Such silence offers a profound yet unsettling experience, reminding us of the harmony and vitality within, usually drowned out by the noise of the outside world.

The Orfield Labs’ anechoic chamber in Minnesota, certified as the quietest place in the world, is a fascinating and unique space. Designed to absorb 99.99% of sound, it is a crucial tool for various applications. The chamber’s exceptional soundproofing, created from layers of fiberglass wedges and insulated steel and concrete, as well as a trampoline-like mesh floor, results in an environment where sound practically ceases to exist. In this sensory-deprived setting, background noise has been recorded at -9.4 decibels, well below the threshold of human hearing.

The chamber serves practical purposes, with companies utilizing it to test and perfect the sound levels of products like appliances and motorcycles, while NASA employs similar chambers for astronaut stress tests. It’s a space of great scientific value.

Interest in the chamber has grown so significantly that the founder, Steven Orfield, is exploring the idea of offering the 45-minute challenge to the public, with the possibility of setting a Guinness World Record for the longest time spent in an anechoic chamber. While this experience promises to be a unique adventure, it comes at a cost, as the usual rental rate for the space is $300 to $400 per hour, and professional supervision is essential for participants’ safety. This chamber’s unparalleled silence truly presents a profound, and potentially disorienting, experience.
