Standard back-touch baize, as used by Steinway, is very firm and the firmer the back-touch the noisier it will be. A soft felt underlay will cetainly make it slightly quieter but you'll still get the slap of the key against the top surface. High class German pianos in the old days used about 5 strips of a special fulled cloth, usually white, about an inch wide in a "tunnel" of thin box-cloth. So far as I know this special cloth is no longer available, though Danielsen in Denmark used to sell a pale blue material they called "Molton", which is the Danish for Melton, that served the purpose well. However it is nothing like Melton or molleton but rather a very soft fairly open-textured fulled cloth. I see they still list it (in white) Cat. No. 1253. <http://www.knud-danielsen.dk/catalougepianoparts/CATALBAIZE.html> Incidentally Kirkman always used two front punchings, a medium-hard baize of about 5mm topped with a green box-cloth punching of about 2.5mm.
