[78-L] A doubt about EQ curves

[bradc944 at comcast.net]

Computer speakers? The speakers I *prefer* to use are the Advent Large, connected to my Marantz 2265  (with the 'loudness' button NOT engaged). The second transfer station, in the heated basement, has a pair of KLH bookshelf speakers. Those roll off at about 16 kHz. Your monitor speakers I'll bet are rolling off around 13 kHz.

Some of that high frequency hearing loss may just be a buildup of earwax that a doctor or nurse could remove (for us) once or twice a year. Of course there are over the counter products that can help keep it out too but I've never used them. the rest of course is age related graduel hearing loss or perhaps damage to hearing due to music played very loud on speakers or headphones as well  as other loud noise..
 
I'm 55 now & haven't been to an audioauligist for years but then as far as I knowI can hear normally for a person of my age. On the other hand my computer speakers seem to drop off at around 13.5 kiloherts when I've run an audio sweep test on them with the graph on my computer moniter. The question is, is that my hearing (with whatever earwax is there) or is that where my computer speakers start to really drop off? I don't know.
