Maybe. But there is room for improvement on the notifications, there is no reason why the phone needs to ring and vibrate on every notification.
If it notified the user a few seconds ago, it should have a delay until the next ring/vibration.

Multiple rapid notifications in a short window of time alert me to emergencies. Phones should be on vibrate in public, of course.
