The Apple Watch Ultra is marketed for extreme athletes who may take on more risky activities in their lives.

I find decibels difficult to understand. Do you know how many dB is a police siren? Usually 110-120 dB! This means that your Apple Watch Ultra is quieter but still comparable to an emergency vehicle siren.
