[AG-TECH] Hursley AG Node - Room Design, please comment.

[Osland, CD (Chris)]

My only comment would be that having the equipment rack in the
same room is going to give you significant background sound levels.
You can only do so much with sound deadening - beyond that the
temperature in the rack rises till the computer(s) switch themselves
off!
 
Also on the sound point-of-view, think about the noise of the
projectors, and see whether you can box the projectors in (and
still ventilate them!) with a glass-fronted tunnel fitted to the
ceiling.  75% of the noise in our room is from the projectors (which
we chose to be as quiet as possible), 20% is the air conditioning
(which was similarly specified) and 5% is residual sound from outside
and from our equipment cupboard which has total hermetic seals
to the room and is separately ventilated.
 
The echo canceller does a great job, and a decent number of
properly spec'ed and placed mics helps a lot, but in the end the
more background sound that's around, the more everyone hears.
This becomes especially relevant when lots of sites are in one
meeting - unless silence suppression is turned on (which considerably
reduces the 'being there' feel of the meeting) the total background
sound level can all too easily drown out quieter speakers (or sites
that have set their sound levels a little low).
 
You have specified a one-way mirror to surround the op; this will
make it impossible for someone to op their own meeting unless you
have the main op consoles up on the wall and, maybe, use a wireless
keyboard and mouse or use VNC on a laptop to run the Display
machine.  We find people self-op for perhaps 30% of our meetings.
 
Could you say hi to anyone you know at Hursley who was previously
at the Winchester Scientific Centre - we collaborated on various things
in the past!

Hi all, 

Thanks for all the feedback so far.  Below is the design I have have come up
with for our AG Node.  I am wondering what you all think of it, will this
work or am I going in completely the wrong direction :o). 

PS Please fogive using arrows as cameras.
