Can my neighbor make all the noise they want?

Generally speaking, no. Long-standing constitutional law requires that all neighbors act as good neighbors and conduct their activities so as not to disrupt or injure the activities of other neighbors. The baseline right remains the right to quiet enjoyment. Contrary to some claims, no right-to-make-noise exists. If there is a bona fide noise problem, the wrongdoer must mitigate, reduce, or stop the disruptive noise.

Unfortunately, we no longer live in a respectful and decent world. Me-first controls for many. wrongdoers may retaliate, harass, or otherwise continue the disruption. If the municipality maintains a noise ordinance (as it should), the municipality may be a resource. Otherwise, talk to a Pennsylvania attorney about next steps and strategies.
