An improvement to a striking bag for boxing or martial arts practice, which provides aural feedback to the user, as to the accuracy of strikes. Compressible pneumatic targets ( 10 -A, 10 -B, 10 -C) are mounted partially into the side of a striking bag ( 9 ). Targets ( 10 -A, 10 -B, 10 -C) are compressible both outside and inside the surface of the striking bag ( 9 ). When any of the pneumatic targets ( 10 -A, 10 -B, 10 -C) are compressed by a strike, displaced air is driven into a pneumatic hose ( 34, 36, 38 respectively) which runs through the interior of the striking bag, connecting the pneumatic target to a whistle ( 12 ). Flexible washers on the inside ( 14 ) and outside ( 16 ) of striking bag ( 9 ) mount each pneumatic target (such as 10 -A), onto striking bag ( 9 ). The inner washer ( 14 ), and outer washer ( 16 ), are connected through the surface of striking bag ( 9 ) by bolts ( 18,20,26, 28 ) and nuts ( 22,24,30,32 ). Alternate embodiments include pneumatic targets ( 10 -D, 10 -E, 10 -F, 10 -G, 10 -H).
