I looked all over for this answer and I think I figured it out, I have my calendar and reminders connected to my Facebook and other social media things...once I turned the sound off for the notifications and reminder which everyday always has something on it from a bday to a appointment I have not heard one beep try it turn it off and if it works pass it on....let me know...
iPhone 5s, iOS 8.3
