Noise cancellation can be a little tricky depending in the frequency. Low frequencies are easiest. Trying feeding the signal through your PC and adjusting the delay, using different delay for different frequency ranges. Some nice thick shag pile carpets, and wall-hung rugs will also help. If you like posters or pictures, consider using a block frame and putting some sound adsorbent material between the paper and the wall. Double glazed windows are your best bet, but probably quite hard to install in a high rise. Ideally you want the ones where each glass layer is a slightly different thickness. Otherwise get some custom fit earplugs from an audiologist, if it's just sleeping that is a problem. They can even fine tune them, so that voice frequencies pass through, but other frequencies are blocked.

More likely to get a pair of these https://www.bose.com/en_us/products/headphones/noise_masking_sleepbuds/noise-masking-sleepbuds.html https://www.bose.com/en_us/products/headphones/noise_masking... Though stopping or masking all noise carries risk by itself... being unable to hear what fire alarms we do have.

  Assuming these are roughly equivalent to their in-ear headphones, I wouldn't worry about missing a fire alarm. They're pretty effective, especially for low frequency noise like aircraft engines, but they're a very long way from blocking all sounds.

    the sleep pods are a combination of average ear plugs, and tiny little speakers playing white-ish noise rather loud. they don't do any active noise cancellation. sounds like they'll be good for somewhere around 90dB of noise masking. still doubt they'd stop a fire alarm.

      Interesting. I hadn't heard about those. I doubt it would handle 90db though. That's pretty loud, probably dangerously so for an extended period; it's about how loud a lawn mower is when you're operating it. Standard ear protection attenuates about 15-30db.

        the 90dB of noise masking isn't all sound energy. they're also ear plugs (on the less effective end of things) so 15-20dB of that 90 is from jamming them into the ear canal.
