I tend to agree. All things being equal and if hearing protection is used, there is a slight hearing loss due to ageing. The only thing I've noticed is my tinnitus gets louder as I dive more often and decreases over time as I don't dive. Usually the tinnitus returns to ambient after two to three weeks of not diving.

Like Pete I've just come to accept it.
Strangely I haven't noticed a change whilst diving so will pay attention next time.
The constant ringing only started after I began on CCR a few years ago (started scuba in '88).
I suspect that it has more to do with my age than it does with CCR,

at least thats what I keep telling myself
