> I get that listening to me repetitously work out a song or musical phrase for an hour might not be pleasant... but is it really as bad as noise from motorcycles, lawnmowers, and car alarms?

At equal volume, it's actually worse. Music is harder to tune out than mechanical noise.

> For those who enjoy hearing their own music but still feel this way: how do you expect new musicians to come into existence, new music to be made? Is it not a racket worth its trouble? Is there any solace in knowing that the person making such noise is doing so with the specific goal of creating enjoyable noise in the future?

No.
