Oh, you scientific mind type folks!! Gotta love ya!
Well, thank you for all of your suggestions...I MAY have found the culprit. After disabling all of the notifications mentioned and STILL hearing that annoying sound...I just happened to be looking at my phone when the sound happened and noticed the refresh bars appeared. So, I went into my settings and looked around and found the "sync all" setting. I disabled auto sync and I haven't heard the sound since. I'm not 100% positive yet but I haven't heard the sound in a while. If I continue NOT to hear it, I'm going to turn the sync on again and listen for it to make sure.
THANKS FOR BEING HERE GUYS!!!
