Apart from family and general events I've been using this lens for seven years now in theaters, concerts, church services and other events where silence was desirable. During the last three categories I generally avoid complete silent moments, by 'synchronizing' as much as possible with available/occurring sounds. - But actually it's rather the camera's click that might disturb someone at rare occasions, rather than the sound of the AF motor. (And with SLT's half of that problem is gone too...!)

It was only in recorded video with the A77's built-in mic that I became aware again of the typical screw-drive motor sound. So - don't worry - you might enjoy this lens a lot, and solve the little motor noise issue with an external mic.
