Will chipper trucks violate the noise ordinance of Burbank, CA?

Most local noise ordinances designate certain "quiet hours" -- for example, from 10 p.m. to 7 a.m. on weekdays and until 8 or 9 a.m. on weekends. So running a power mower may be perfectly acceptable at 10 a.m. on Saturday, but not at 7 a.m. Some universally disturbing sounds are commonly banned or restricted.The following link provides the Burbank Municipal Code Sections that will give you information regarding the most common issues in relation to noise control in the City of Burbank. http://www.burbankca.org/license/noise.htm
