What is the noise ordinance for the city of Baltimore Maryland?

Answer 1

This is the only information I could find concerning Police noise ordiances within the city limits: § 43A-1. Definitions. (c) Neighborhood nuisance. (1) "Neighborhood nuisance" means any premises where, on 2 or more separate occasionswithin a 6-month period before the start of a proceeding under this subtitle, an owner or tenant of the premises engaged in acts or created or maintained conditions that: (i) significantly affected neighboring residents by being disorderly in manner; or

(ii) disturbed the peace of neighboring residents by: (A) making an unreasonably loud noise ; or

(B) the unreasonable use of profanity, cursing, or swearing. (2) The 2nd report by a police officer, written in the regular course of business, of behavior or action of the type described in paragraph (1) of this subsection is prima facie evidence that a neighborhood nuisance has occurred. So, there is no set time or decibel limit to playing loud music. It's very vague.

Basically, if you're playing music and a neighbor can hear and calls the police, it's the officer's whim to decide whether or not it's unlawfully loud. You can always argue that your band practicing one day a week for only a few hours in the early evening does not "significantly affect" your neighbor and that your music is not "unreasonably loud".

Use the vaguness of the law for your side as well.
