“Incredible,” I thought. Right when I stepped into the Anechoic Chamber, I was immediately able to tell the difference. Everything outside the chamber was muffled, and the door was still open. The walls were made with a type of foam, placed in certain angles so sound would be able to bounce and reflect off from the wall onto each other. The floor was made of wired mesh, and feet below the flooring was more foam. Taking a visit to the Anechoic Chamber blew my mind, so I decided to research further into it.
The definition of an anechoic chamber is a shielded room designed to attenuate sound or electromagnetic energy, otherwise known as a room with special walls that take in as much sound as possible. Sometimes the room is actually built on shock absorbers, opposing any vibration from the rest of the building or the outside environment. It was originally used to absorb sound echoes caused by reflections of an enclosed space, but nowadays is also used to provide a protected environment for radio frequency and microwaves. There are two types of anechoic chambers: EMC chambers, which are used for testing electromagnetic compatibility, and antenna chambers, used for testing any kind of antenna patterns.
Earlier in the day, Pinar gave us a presentation about art, and briefly mentioned the topic of granular synthesis. She provided us with certain pictures, which in truth were very interesting. Later on, she also showed us video, which I thought was really creepy. Doing research, I found that the definition of granular synthesis is a basic sound synthesis method that operates on the micro sound time scale.
