An interesting short radio segment on an anechoic chamber considered the world's quietest room.

I spent some time in the anechoic chamber at the Axiom plant up in Dwight. I was given a fantastic tour by the guys up there this past summer. Ian had their chamber built to the exact specs as the one in Ottawa at the NRC.

Very freaky after about 15 minutes.

The guys at Axiom are fantastic and treated my wife and I like we were family. 8)

I've heard you can actually loose your mind if you stay in a room like that too long.

Wonder how my tinnitus would sound in there?

It would drive you or I mad in a half hour, the ringing would be so loud.
Hard enough going through every day and night as it is.

I'm actually a bit interested to hear the new AXIOM stuff that Andrew Welker (Aka: MIRAGE ! ) is designing for them ...

I wonder if tinnitis was as common before the hum of electricity?

You start to hear the fluids moving inside yourself in about 5 minutes. Your sense of time excellerates and about 10 other freaky things. It would not take very long for panic to set in and 20 minutes was more than enough for me.

Ian has an awesome test set up and the gear outside the chamber is overwhelming. He made countless trips to Ottawa and clearly decided to build his own duplicate at home. He has an huge chunk of land and facilities. The chamber from the outside just looks like a big office or something off the ground inside the building.

Like I said it was a great tour, we were there for a couple of hours and they showed my wife and I everything. We had a blast.

It goes back...wayyyy back
http://www.tinnitus-audiology.com/history.html
Quote:
The first written account of medical treatment of tinnitus is all the way back to the Egyptians. For the bewitched ear and humming in the ears, they would infuse oil, frankincense, tree sap, herbs, and soil; and they would administer it via a reed stalk that they put in the external ear. The Mesopotamians documented on clay tilework their rituals and chants, and they used to chant to get rid of the whispering or singing in the ears. These are two of the chants. "Whoever thou may be, may E restrain me." This is E depicted in the figure. He was the god of water. The other incantation was, "It hath flown against me. It hath attacked me. O seven heavens, seven earths, seven winds, seven fires, by heaven be ye exorcised." I do not think they worked.

Quote:
In the 19th century, the work of Frenchman, Jean Marie Gaspard Itard advanced the study of tinnitus with some progressive ideas that we still adhere to today. Most tinnitus is associated with hearing loss. He gave the earliest descriptions of objective versus subjective tinnitus, and he recognized that the treatment often failed but, meanwhile, the physician was to make the tinnitus less unbearable. Usually he did this with masking. Finally, in the 19th century, we saw advances in technology and in the germ theory and anesthesia. Electrical stimulation evolved as a treatment, and germ-free surgery allowed more attempts at surgical therapy, including ligation of offending blood vessels as well as incudectomy.


As with most medical problems there is more diagnosis today than yesteryear...but does thaty mean there is more problems today...or just more diagnosis?

Gives you an idea on how important our sense of hearing is.

Helen Keller, when asked what sense would you want to have back always replied
my hearing.

Mine manifests itself as a very high pitched whine. Funny thing is, in spite of it, I seem to be able to hear high frequency noises that don't bother anyone else, computer hard drives, fluorescent light ballasts, etc. I have one ballast in my house that drives me crazy, need to fix that.
