Anechoic chamber or the really weird room

The first time I stepped into an anechoic chamber it was a really weird experience. Your equilibrium is out of whack and you suddenly realize how important sound is for a person just to maintain balance. With eyes closed and alone in the sealed chamber I could hear a low frequency sound and a high frequency sound. These were coming from my body. The circulatory system and central nervous system. When in the chamber with other people you can hear the heart beat of the person next to you. These were really great but weird experiences and probably taken for granted by those who work with these rooms for testing speakers.

The anechoic chamber in hope is very unique and was also awarded a patent which was awarded in 1980. Download the patent pdf click here. The chamber is unique in that it has a multi ton rotating corner/door. The door has three sides 1. perfect corner for klipschorn testing 2. a mount for testing individual drivers and horns 3. anechoic corner to complete the chamber with no flat surfaces.

Great pic of PWK showing off a beautiful Klipschorn in the chambers corner.


This is the chambers anechoic corner being rotated.


This is the side used for testing drivers directly mounted to the door.


One of the other corners.


Klipsch employee Chris at the door. The door also swings very easily. It is perfectly balanced.


This is possibly one of the best fully horn loaded speakers ever made. I am preparing a rather lengthy post for a later date on this speaker. It is the Klipschorn Jubilee. This was PWK's last design.
