Well, they do need to overcome my noise-cancelled high-volume drown-out-coworkers music...

Listening to high-volume music every day can damage your hearing.

  Listening to my coworkwers can be worse!

  With active noise cancelling, the music can be loud relative to co-workers and alarms but not dangerously loud in absolute terms.

At one of my former workplaces we weren't allowed to wear over-ear noise cancelling head phones because of the risk that we didn't hear the fire alarm.

A couple year ago, I was listening to music at a super low volume (way below that of people talking around me, if I removed the headphones) when fire alarm triggered. I didn't hear it. A coworker did pat my shoulder to let me know, and I noticed the super loud fire alarm as soon as I removed the quiet headphones. The headphones were not noise-cancelling or anything. Just Sennheiser HD380 Pro, which provide ~30dB isolation. I don't think it would have been possible for fire alarm to be noticeable under such conditions unless it was loud to ear-damaging levels. This suggests that alternative indicators than just sound should be in place, such as automatically turning off lights and switching to emergency lighting.

  Small children have this problem when they are sleeping. They just don't wake up from high-pitched noises, but require lower frequency alarms ideally with spoken words: https://www.bbc.com/news/health-38918056 https://www.bbc.com/news/health-38918056

    I wonder if this is an adaptation to not be woken up by infants crying at night until they're old enough that sleep isn't as important or they're able to help?
