You don’t even have to wear mitts or gloves to make AW practically inaudible.Wild guess is that they just don't notice crash detection went off and is about to call first responders - which makes sense if the phone is buried deep in your coat pockets as you're skiing (watch users may have a different pattern, but heavy skiing mitts likely don't help here hearing/noticing the crash alert and timer).
Any sleeve of a thick sweater or jacket is enough to muffle it to a point where you’re only going to hear it if there’s no background noise.
Obviously also depends on volume levels. But still it’s not loud enough.
This gets even worse when considering that AW is emitting sound from only one speaker. This speaker is, when worn on your left wrist, located on the left side and thus emitting audio in the direction of your upper arm, not out of your sleeve towards your hand.
The Ultra has an additional speaker with the Siren feature. But those are also both located on the left side of the Watch like on regular AW.
Apple is not going to fix this through having users hear their AWs and disabling the emergency calls with their icy cold fingers on a touch screen display.
The algorithm has to get better at discerning an actual accident or Crash Detection is doomed to end in a class action lawsuit.
This isn’t just a nuisance for users but a huge cost for dispatchers.
