Zusammenfassung:	A rock drilling rig includes a movable carrier with a boom attached to it and movable in various ways. The free end of the boom is provided with drilling equipment. The drilling equipment is enclosed in a casing that prevents noise generated during drilling from spreading to the surroundings.

A flexible noise attenuating skirt projects forwardly from a front end of the casing for forming a sealed chamber around a drilling head.
