San Francisco authorities will be at the Rolling Stones concert tonight, but not for the music.

They'll be measuring how loud they get.

Officials were flooded with complaints from nearby residents after the Stones' show at SBC Park on Sunday. Neighbors complained of windows and floors vibrating.

One man who complained said, "just because they're too old to hear their music doesn't mean their music has to be so loud."

The executive director of San Francisco's Entertainment Commission says his phone started ringing as soon as the Stones began playing.

Bob Davis says the city will monitor whether stadium officials are obeying noise laws. Officials from the Giants baseball team, which owns SBC Park, say they will try to reduce the noise level.
