Inside the Anechoic Chamber

On November 23rd, artist Elisa Ferrari and Ms. Persoon’s grade 6/7 class took a trip to UBC to visit one of the quietest places on Earth: an anechoic chamber. Designed to eliminate all reverberation, anechoic chambers are virtually soundless.

Composer John Cage famously heard two sounds when he entered the anechoic chamber at Harvard: one high pitched and one low. When Cage asked the engineer what produced those sounds, he replied that the high pitched sound was Cage’s nervous system and the low pitched sound was the circulation of his blood.
