Full Breakdown
Pennsylvania has no general statewide decibel statute for everyday noise; that is left to municipalities, and Chester County itself sets no decibel ordinance. The one measurable statewide standard is for motor vehicles. Under 67 Pa. Code section 157.11, sound is measured at 50 feet from the center of the travel lane, and maximum levels at 35 mph or less are 76 dBA for most vehicles, 82 dBA for motorcycles and 86 dBA for vehicles over 6,000 pounds. Higher-speed and hard-surface limits run a few decibels higher. Municipal noise codes like West Chester's use a 'plainly audible / unreasonable noise' standard rather than a fixed decibel meter reading.
Violations & Fines
Exceeding the vehicle sound levels is a Vehicle Code violation with a fine and possible inspection failure. Municipal noise violations follow local penalty schedules (summary offense with fines).
