The present invention provides for a metal framing member having improved sound attenuating properties to reduce the sound transmission through a partition wall constructed utilizing the framing members. The framing members have a central web which bridges the interior of a partition wall, attached to either edge of the central wall are upstanding side walls to which the covering material would be attached. The central web is provided a plurality of paired rows of elongated slits oriented along the longitudinal direction of the central web such that there is no uninterrupted line of metal bridging the web from one edge of the web to the other in any transverse direction.
