I've heard many times in Colombia that it's customary to accustom babies to noise when they sleep. Also people love their subwoofers here, and partying until dawn. I bought an apartment in a community with a huge fraction of old people to escape that. I've seen people here sleep through experiences I could barely think during. Even my own brain appears to have acclimated somewhat, though. Last week I got some nice noise-canceling headphones, and each time I take them off I'm shocked to realize how noisy the environment is, unless I'm at home. (Actually even at home, when I'm running the air filter, to protect myself from a different kind of pollution ...)
