- What can I use to test the extent of my hearing? The human ear can
- distinguish pitches from 20Hz to 20000Hz, but when I went to a "specialist"
- his equipment only tested 500Hz to 5000Hz. The low pitch, 500Hz, is
- approximately the C *above* middle C on the piano; being a musician I was
- hoping to test the true high and low ends.
-
- My reason is that I have a ringing in one ear which seems to get
- worse after an ear infection. I'd like to establish a data point now, so
- that in the future if it gets worse I'll know how *much* worse it gets; i.e.
- how much more of the high end I've lost.
-
- I'd appreciate anything, even just the name of the proper equipment
- so I know what to ask for. In engineering terms, I need a function
- generator that lets me control frequency (at least 20Hz to 20000Hz), and an
