I´ve been thinking about getting some molded earplugs, making a channel in them and connecting it to a tube of required length, the tube would have an internal measurement of no more than 1mm, it would be able to let the pressure of the water push the air further into the tube compressing the air between the plug and the eardrum, the little diameter of the tubing would be to narrow for the air to escape (I think), hence directing the right pressure, but not letting the water travel past nor fare enough for it to enter.
This would be eliminating the risk of suddenly getting wrong pressure between the plug and the eardrum which is the normal no go part with earplugs.
Have tried the proplugs, but it ended up as a stressful dive, but then again I put them inn as I left the house, so my ears where fed up with them once i finally got in the water
, will probably give them another go
thanks for feed-back so fare
