Re: Hearing Loss "False Positives"

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.

I think you're misreading this.  The paper says that a reasonable statistical model reveals that the method used in previous studies will find roughly 10% of children with normal hearing to have a measured hearing loss that isn't real.  You subtract that from the 14.9% figure and you get less than 5% of children with high-frequency hearing loss, and probably the majority of these are from causes other than loud noises.

Dear Kevin,

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?

Begin forwarded message:

A new study from the University of Minnesota says that we're overestimating the amount of teens with hearing loss. 

Thanks in advance.
