Natural Loss Hearing: Presbyacusis. When Does It Start Posted: 04-30-05 22:05pm
Hi,
i am looking for some sort of (academic?)
document which has some sort of info,
statement about the natural loss of high
frequencies for people between the age of
20 and 40 years old. As far as I always
thought was true is that starting from a
young age you gradually have some loss of
frequencies, or shift of hearing
threshold. However, now I desperately
trying the find some sort of info on that
topic for my ba (hon) all I can find is
loss of hearing due to old age and
abnormal causes.
Could someone give me some advice on were
I can find something like this?
