Ridgefield, CT Noise Ordinances: Amplified Music & Outdoor Sound (2026)

Chapter 250's only amplified-sound provision, § 250-7(B), is written narrowly around vehicles: no sound-amplifying devices on or within motor vehicles shall emit noise in excess of the noise level specified in this chapter. That incorporates the general table in § 250-3, so a vehicle's stereo, speakers or PA system reaching a residential receptor cannot exceed 55 dBA in the daytime hours of 7:00 a.m. to 8:59 p.m. or 45 dBA at night, measured about one foot from the boundary of the receiving property. Ridgefield's code has no separate ordinance for a stationary outdoor speaker, festival PA system or bar sound system; those would be evaluated under the same § 250-3 zone table as any other noise emitter, since § 250-7(B) is written specifically for devices on or within a vehicle rather than fixed equipment. The section carries no exemption of its own, so it applies at any hour a vehicle is present, day or night, in any zone.
