Sound alert for indicator

I would like a sound  alert and email alert for my volume indicator.

I have the code for the volume indicator and would like an alert when the volume bars turn to certain colours in specified timeframes - example an alert when the  volume bars turn green in the  1 hour, 30 Min or/and 15 Min timeframe. There are only three colours that I'm interested in .

Thanx
