In the pipe organ industry we use heavy felt to dampen the noise from relays.  The relays pictured are mounted on a circuit board that has felt backing that is 1/8" to 1/4" thick.  This is screwed to a board with felt isolation washers between the screw head and the circuit board.  The mounting board also has a heavy felt backing.  The relays are enclosed with a removable top.  This is also lined with a sound deadening material, usually felt.  This particular example used foam rubber which deteriorated over time.  I try to avoid foam products for this reason. 

 

This usually deadens most of the clicking associated with electro-mechanical relays.

 

Incidentally,  these relays were salvaged from a pipe organ project and will be used on my train layout.
