St. Patrick's Day is fun, and fun can get loud. And loudness that annoys your neighbors might get you in trouble, so it's best to have information on Boston noise ordinances for St. Patty's Day.
Under Boston Municipal Code's Chapter 16, subsection 26, "unreasonable or excessive noise" means noise measured in excess of 50 decibels between the hours of 11 p.m. and 7 a.m., or in excess of 70 decibels at all other hours; or it can mean noise that can be plainly heard at a distance of 300 feet.
