Hi Andreas,

thank you for your interesting report - not only for the weather it was 
a pitty that my easter break finished a week a ago, so there was no 
chance to attend.

Now, this is puzzling, but luckily there were some medical scientists in 
the track! I wonder...:

Is there samples of the sound? Could you compare its loudness to other 
sounds (wouldn't expect a dBA value)? Especially, when you were able to 
anticipate the next knocking: Could you determine any directions? What 
was the meeting room alike? Wooden walls? The interval of exactly 10 
minutes points to a technical source, like a clockwork or even some 
heating/climate turning on/off. A water pump? What kind of building 
were you in?

Take this story to the rainbow press - and slashdot will follow ;)

Kind regards
Ralf
