Startled out of my Skin

I am sitting here at my computer, working away, when this awful noise startled me out of my skin.

It was my MDA, Melvin. The sound is one he makes when he completes synchronization with my desktop computer. The sound is not supposed to be so loud.

This has happened before, but it is not predictable and therefore startles me every time. I would like it not to happen, but since I can’t pinpoint the cause, I doubt that tech support could be of any help.
