Ever been subjected to regular concussive force like from large firearms with muzzle brakes?"
adding from personal experience
for quite a few years l was an RO of a range that could hold 100 shooters, if l did one busy day being an RO it was ok but after 2 days straight the smallest noise was very painful, it usually took up to 3 days to become normal again
my wife said it was like a lack of interest eg.. being hungover
there were times l would do 3 days straight.
l was helping a new guy from the military rifle club sight in his 50 cal and made the mistake of standing near his bench that l put well away from everyone else
l was hit by the muzzle blast and nearly fell over putting my back out, l struggled to my car went home and spent 3 weeks mostly in bed
l have also had jobs where once a week doing maintenance in a fertilizer plant a couple of us would have to t-hammer the floor to remove tracks that were made from the bobcats under the machines that made super phosphate, very loud and done at the end of the week, it did take the weekend to get over
the effect was not as bad as being an RO at a busy range for 2 days
an edit: l would like to add that the guy with the 50cal could only get it in Victoria because he became a member of the military rifle club,
after joining he wondered why he had not done it years ago
