  > And when hasn't getting too close to music required hearing protection? Even a flute is over 90 dB. Not that it's impossible for a symphony to play so loudly that one needs ear protection but that the giant speakers on the concert stage are engineered and tuned to output sound that's as loud as possible such that everyone within a certain distance of them is likely to suffer hearing loss without protection from such damage.

  > Wait, how do closed-loop air conditioners poison anyone? Not parent-poster, but I believe "closed loop" is referring to having no air exchange between inside and outside atmosphere of a room, as opposed to the refrigerant flow inside the air-conditioner itself. So somebody trying to make their cooling or heating effective (or extra cheap) may inadvertently seal off too much ventilation, and then a crowd of humans becomes in danger of their own CO2.

    Surely that would happen in any building with inadequate ventilation regardless of whether there's an air conditioner or not.

      I think the idea is that a major reason for inadequate ventilation comes from venues cheaping-out on their air conditioning setup. Not because of containing noise, or a strange aesthetic decor, etc.

      Inadequate ventilation without air conditioners is unbearably hot.
