Protect St. Louis Symphony Orchestra workers?

If St. Louis City needs to pass a smoking ban to protect bartenders from tobacco smoke, should it also enact a workplace sound law to protect St. Louis Symphony Orchestra workers from their own music? Loud music is an even bigger problem in St. Louis bars and concert venues. Bartenders at the Pageant can't plug their ears and fill drink orders. A friend who works at the Pageant says this is a real problem. I have always said that I wouldn't let my daughter work at the Pageant not because of the smoke but because of the sound levels.
