Hi Manolis!

I have been checking your blog page and doing some research and found the
following pages to be interesting. (I hope you dont mind me giving you
feedback via the list. If you do, please simply reply to me directly.)


(you need to register with the NY Times...)
This is called "cone of silence". Rather than actually creating silence it
uses ambient sounds and scrambles them in a way that your surroundings wont
be able to listen in on your conversation.
Nice technique and very similar to the sound curtain idea by the RCA student
I told you about, which unfortunately is completely offline now..

This is a device for aging bird lovers that uses pitch shifting to make high
frequencies audible. Not a design highlight, but intersting area as there
are a large number of animal sounds that are below or above our hearing

This is a nice one as well. Make sure you download the soundfile at bottom,
which is created by speeding up the realtime recording to a level it becomes
There are a lot of (natural) cycles like this around us that are very hard
to experience due to their duration. This kind of thing does need some kind
of microprocessor in reality, but you should be able to simulate (playback)
in a show/demonstration.

Regarding the whole electromagnetic spectrum/electro smog things I would say
that its been worked on quite a lot in recent years. There is Christina
Kubisch's work and of course Tony Dunn's book and somehow I feel it would be
nice to explore something that didnt have this much exposure.

hope to see you later today.
