摘要： A sound absorber mountable between a drilling apparatus and a drill bit. The sound absorber defines an absorber axis therealong. The sound absorber includes a sleeve defining a chamber extending axially therealong, the chamber defining axially opposed chamber proximal and distal ends, the chamber being delimited by a chamber peripheral wall extending between the chamber proximal and distal ends and a chamber distal end wall provided at the chamber distal end, the sleeve defining a sleeve aperture leading to the chamber at the chamber proximal end. A piston is mounted to the sleeve so that at least part of the piston is in the chamber, the piston being reciprocatingly movable substantially axially along the sleeve, the piston defining axially opposed piston proximal and distal ends An absorbing system includes a first resilient element provided in the chamber between the piston distal end and the chamber distal end.
