Sound Noise and Music Curiosities
Which of these is a bizarre reality regarding how human ears perceive silence in an anechoic chamber?
Correct
In an anechoic chamber, where external sound is almost entirely absorbed by the wedges on the walls, your ears become hyper-sensitive. The brain is so desperate for input that it tunes into the internal percussion of your own body, making your heartbeat and the rush of blood in your ears sound like a drum solo. Ears do not shut down, as they are always waiting for the next signal. While ambient noise is cut out, the Earth core hum is not something humans detect in this setting. Though some people claim to feel uneasy, the chamber does not magically turn into a haunted broadcast station for your brain to start projecting voices.
