Yosemite/Safari/iTunes/Bluetooth

Question

In the middle of using my computer, while on Safari, listening to iTunes, a song will stop and a super loud white noise at volume 11 takes over and won't stop unless I push pause, close my MacBook and/or shut off the power to my bluetooth speaker.  This never happened prior to Yosemite.  Please help me stop this.  The noise is insanely alarming and scares **** out of me and my cats because it happens for no discernible reason or cause (except when switch from one web page to another).
Thank you.

SMC and PVRAM resets do not change the issue with Bluetooth and Yosemite view this threadSudden loud static noise on bluetooth headset and you'll find many of us have exactly same problem that hasn't changed loud outbursts and dropped connection as well as mouse and keyboard losing connectivity only this trick helped me but not a fix for outburstsThe standard setting prevents conflict with other Bluetooth devices. If you'd like better audio though, you can change the settings with this terminal command:
defaults write com.apple.BluetoothAudioAgent "Apple Bitpool Min (editable)" -int 40
This command works in other versions of OS X, but the Bluetooth Audio problems seem worse in Yosemite than previous versions. The number 40 is the sound quality setting. Note: a higher number could cause compatibility problems with other Bluetooth devices, so start at 40 and work your way up.
