I guess it will mostly reflect the musical taste of assholes who turn their music up loud. Hmm, but maybe all culture works like that.
Highly variable of course - but I've found these types of self-centered narcissistic attributes to be far more endemic to western culture. I don't remember a single time in my years of living in Taiwan where I heard somebody blaring loud music / subwoofers, both while walking around and in all the flats that I lived.
It might reflect different attitudes between cultures as to what volume makes one an "asshole".
