ANECHOIC TEST BOX
Many myths surround these surreal and fascinating spaces. Some people claim that the longest anyone has spent in an anechoic chamber is forty-five minutes. They say any longer would drive you insane.
Effects on the human body
Being in extreme silence has an interesting effect. With no sound to distract you, your body becomes the sound field. If you spend some time in an anechoic chamber you will hear:
- Your stomach rumbling and gurgling loudly
- Your throat swallowing
- The hissing from your breathing lungs
- A low-pitched hum from your ears – louder than the effects of tinnitus
- Your heart beating loudly – you may even become so aware of your heart that you feel your chest moving from the heartbeats
Not a pleasant experience. Some people can only endure a few minutes of this strange, overwhelming silence! However, the record certainly stands at more than forty-five minutes.
David Muller from Veritasium made a video investigation where he was able to spend a full hour in an anechoic chamber – and claimed he could have stayed in there for hours.
