The Les Schwab Amphitheater is getting an exception to a noise ordinance in Bend.  The new rules for loud events exempt places with a capacity for more than 5000 people.  The ordinance, which was adopted last month, bans smaller loud events between the hours of  10 p.m. and 7 a.m.  Amphitheater Director Marnie Smith told the council last night that the three concerts held mover the Memorial Day weekend generated no noise complaints to the Bend Police Department.
