Real silence, who's scared of the big bad wolf

I caught an article on the news recently, it's about a room which has been built to provide perfect silence. This is supposed to be great for recording sounds, but it also has the purpose of making some people scared. Not everyone, just some. Probably the ones with the biggest mouths and like to hear themselves speak. Getting peace and quiet is probably my pet love and pet hate when I can't get it. Silence has a purpose, this purpose is to allow thinking. Whereas those who don't like silence are unable to cope with their own solitude. Or have very boring jobs. Silence to them is like facing a bad tempered wolf, it scares them.

In the Fish Factory it is difficult to think. The Fish Factory is open planned, it has not been designed for people to think or do cognitive work it's been designed for battery chickens. They all sit at desks and constantly cluck away. What are battery chickens good for I ask? Not a great deal in real terms, they produce eggs and that's about it. Ask them to write a spread sheet, compose an email, or weigh conflicting information on scales and they have difficulty. Ask them about eggs and they are fine, eggs are great, they have a fat end and a thin end. They roll about and of course can be used in food. They have their own value, of which there is no doubt, but they are not very good and complexity.

This silent room has been built at the University College London., and is called an "Anechoic chamber."  I thought it might be full of some kind of soft material which absorbs sound, but instead is composed of many triangular fibre glass protuberances.  Apparently as sound hits these shapes it is then diverted by adjacent surfaces and loses it's energy. The result is a dead like environment for any kind of sound at all. So recording the sound from say a musical instrument would mean it is only the sound which is recorded and not the reflection of the sound or any outside sources of sound. The recording becomes a pure representation of the object which produced it. 

Personally though I think I'd just like to sit in the room and listen to the sound of nothing at all. It seems to me a great way to unwind. Just like at night when going to bed and finding everything has gone silent. There is not traffic noises, no trains running and the rest of the world has put itself to bed as well. Except of course for the wolf. He's keeping me company and just waiting for the next needy nincompoop who loves the sound of their own voice. He comes in pretty handy then.
