Could be with me too. I'm 47 now and the limit to my frequency range is
already down to about 14.2 kHz. There may be other deteriorations too,
I suppose.

However I understand that lateral imbalance in hearing is measured as
a difference in hearing threshold and a difference of 2.7 dB would be
considered as unimportant. More than 10 dB (as I read it from the web,
anyway) is considered significant.

I could not find any material on hearing imbalance at other than hearing
threshold levels which might contribute to my needing to use a stereo
balance control.

The reason there's little about it is that small imbalances like this
are almost always readily adapted since we use this for localization
and navigation. If you have no indications of such imbalance outside
your stereo environment, it is probably something in the system/room.
I suggest that you do a more careful frequency-by-frequency
measurement in order to distinguish a simple imbalance from a
lateralized frequency aberration.
