NONE OF US HAVE CORRECT SIGHT OR HEARING
This applies to all people of all ages, and changes (worsens) with increasing age.
There are great similarities between sight and hearing, as well as all other senses, for that matter.
We are endowed with a pair of eyes and ears, which are never quite identical.
They both lie as far as sharpness, depth, light sensitivity, perspective and color are concerned.
Almost all people will also develop cataracts and crooked corneas when they reach a certain age, as well as impaired hearing, often in the form of tinnitus.
The probability of this occurring increases from the age of 50 onwards, but mild symptoms appear many years before this; estimated from the age of about 37 years.
Most of us musicians are well within this limit or above, which has consequences for how we perceive sound in relation to younger musicians.
Already at a young age (in my early 20s) I started to self-test my vision and hearing, and was then surprised that both eyes and both ears were quite different - I did not know that this was normal.
I found that an object shifted its position by several centimeters from one eye to the other, and that sharpness, depth, light sensitivity, perspective and color accuracy varied.
Hearing had the same result - an instrument shifted its position by several centimeters from one ear to the other, and the level of detail, depth, sensitivity in dB, perspective and frequency range varied.
As a result, I have learned to consistently use one eye and ear for critical observation and listening; the ones that are most correct.
I also found that I perceive correct perspective best with the left eye and ear, while sharpness and detail were best perceived with the right eye and ear.
My work has for many years consisted of fine mechanical work as well as loudspeaker development, and this early awareness of my own limitations has been used as a strength - not a weakness; when I read a micrometer, I use the left eye, because this reads the gauge most correctly as a result of this eye having the most correct perception of perspective.
