But what is the "bandwidth" of the average human ear !!

Ask an audiologist. I presume this is well-established.

10 to 20 kHz depending on age (higher if you're younger).

When I was younger, I could hear out to about 18 kHz. It doesn't mean that
an audio source that was "limited" to 15 KHz would sound as if it was
obviously deficient, however.
