Our washer in the basement discharges into twin wash tubs. When this happens we hear loud gurgling in the sink drain upstairs in the kitchen. They share a common drain pipe to the sewer line. Any suggestions about what can be done to stop the noise?

Now this one *is* a venting problem:-) Either the wash tubs were tapped in improperly or the vent for the kitchen sink is blocked.
Without a working vent, the flow of water from the tubs creates a vacuum which tries to suck the water out of the kitchen trap.
It's even possible that there never was any vent; this type of connection was common in some parts of the country for kitchen sinks.
The best (easiest) fix in this situation may turn out to be the addition of a mechanical vent just downstream of the kitchen trap. How you do that depends on the layout, etc.
Here's one:

Thanks for the reply, Jim. I will check out the venting.
