I just completed reading A Little Detail by Gary Rose, M.D., FACS in Dan's Alert Diver Magazine, Q2 2022. In summary, it describes his external auditory canal barotrauma caused by this hood sealing air in his ear. The author blames it on forgetting to vent his hood before descending. It struck me as very odd since punching a small 1/8" or 3mm hole in my hood for each ear has been my practice since my dive instructor recommended it 60 years ago.
Custom punched vent hole for ears. Paper inserted in hood for photographic purposes.
There have been a number of times I forgot to punch ear vents on a new hood but the first dive reminded me of the error. My question is: isn't this standard practice?
