I would welcome some more hard data. The only data I have is knowing that some of my summer students the last few years I had any at Bell Labs had worse hearing than the 50 year old guy who has worked in the audio industry for 35 years has. Obviously, this is a limited sample, although the existence of loss is not merely anecdotal.

In the link, it says "10 percent of the 14.9 percent figure"; admittedly, that can be interpreted in two ways. I still tend to favor mine; but even 4.9 percent would be worrying. Anecdotally, one of my grandsons did damage his outer hair cells by a loud noise, namely by that of a fire cracker. Loud music is dangerous too, I think.
From a non-professional: 10 percent of 14.9 percent is about 1.5 percent; that leaves 13.4 percent of teenagers with hearing loss, which is still frightening. From "Molecular Biology of the Cell", Part V, Chapter 22: "Auditory Hair Cells Have to Last a Lifetime".
Would anyone in the professional community care to comment on this?
