Notifications are one of the strong points going for Android and yet a Google app somehow has more permission than the owner of the device to determine how it's notifications should afflict the owner. The app-provided sound is obnoxiously loud, to the point of being irritatingly startling in a quiet environment (where I live 99% of the time). Further, not all events require the same "level" of attention-grabbing power, but the calendar app offers no distinction for event importance.
