the study seems to be pretty simple and the difference was between people living their usual life without music
or with music on headphones, VS having to use the sonos stuff. they didn't actually turn the families into zombies all carrying headphones on their heads while eating and sleeping. although I don't doubt it could have a negative impact on social relations ^_^
now in general, I still agree with the conclusion in the title of the topic outside of the study. if you can afford to have the music blasted through speakers anytime you like, you're more likely to have more money and live in a house where neighbors aren't an issue, right? ^_^
and then it really has nothing to do with music, as it's already shown in another study that people with more money tend to have more sex.
did I deduce wrong?
