A client has an business where the small offices are separated by a wall with a standard sliding door size piece of glass set horizontally. They would like to dampen the sound transmission between offices. Any suggestions? would mounting another piece of glass with say an inch space do the trick? Help!

If the offices are truly sealed off from eachother, and the glass pane is the weak link, then you might be able to solve it using tried and true techniques. Please note, these are just ideas - I've not put them into practice on a project yet.
1. Reduce vibration - if you mount a piece of glass over the existing window, use a silicone or urathane that will maintain flexability to seal the new glass in and reduce the vibrations. Also, you can put your fasteners through rubber bushings in the glass frame to hold the weight without transfering the sound vibrations.
2. Change the medium - whatever the thickness of the existing glass, make sure your new glass is a different thickness. If they are the same, vibrations hitting one side sound almost the same when they get transmitted back out the second pane, like a hollow core door. Make the second pane thinner or thicker will change the properties of the sound waves, possibly making them part of the background noise instead of sounding like a conversation next door.

Splitting the jamb on that window as well as tilting the plane of the new pane will help.

How much tilt are we talking Cal?

Oh man, you push my memory.
On a radio station job wayyyyy long ago. The walls finished out at............8''. The inside glass was say an inch in from the fin. wall surface, and plumb. The exterior (noise side) glass was tilted down starting an inch from finish at the top.........probably 1-1/2'' separation between the panes at the bottom. Jamb split and a foam/rubber gasket separating. Glass was set against a foam strip, stopped with wood and foam strip.
I think.
'79 or so.
The idea was explained as noise vibration from the non-studio side would hit the glass and bounce down and away rather than direct vibration bouncing straight at the other glass.
