If he disrupts your Bach [country & western] with his Flintstones then it's an offense regardless of property.

Ah, but if I blast my "culture" out the window, and he blasts his "culture" in my direction, which is the offense? I say it's the volume, not the quality of the culture. Hence the solution is either a "volume control constabulary" or a large country estate.

I'd say it's mostly volume in your example (because there is nothing offensive about Flintstones or country western but volume), but it's content as a general rule. If your neighbor's music consists of "me so horny die bitch die", then it doesn't need to be loud to be offensive at least for some folks. See my example with condom distribution near a church.
