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.
- ghaff 8y agoInteresting. 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.
- sigstoat 8y agothe 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.
