Abstract (en)
[origin: WO0054002A1] The present invention is directed to a method for selecting pressure wave suppression devices from among a menu of pressure wave suppression devices to satisfy the pressure wave requirements of a given job or application. The present invention is further directed to pressure wave suppression devices that can be used in the hole, at or near the opening of the hole, or at a distance from the hole to perform pressure wave and/or flyrock protection. The invention is particularly useful in suppressing airblast and other excavation equipment noise in urban areas.
