Summary
Green Bay defines nighttime hours as 10 p.m. to 7 a.m. and weighs that timing as a factor in noise complaints, rather than imposing a flat after-hours quiet curfew.
Nighttime hours means the hours between 10:00 p.m. and 7:00 a.m.
Produce means, when referring to producing noise, to physically activate the source that creates the noise, to order or authorize another person to activate the source that creates the noise, or to have control over a source of noise and permit the noise to exist.
(b)Unreasonably loud noise. No person shall produce unreasonably loud noise. A court shall consider any relevant factors to determine whether any noise is unreasonable, including, but not limited to, the following:(1)Decibels. A court may determine any noise is unreasonable solely because it exceeds 80 dB(A) using an A-weighted sound pressure level instrument when measured from any property not under control of the person producing the noise.(2)Time of day. Certain noise that is reasonable during daytime hours may be unreasonably loud during nighttime hours.
Full Breakdown
Green Bay's noise code defines nighttime hours as 10 p.m. to 7 a.m. and daytime hours as 7 a.m. to 10 p.m., then uses that split as one factor in judging whether noise is unreasonably loud: sound that's fine during the day can support a citation once nighttime hours begin. It isn't a blanket after-hours ban, the ordinance also presumes some nighttime activity reasonable, such as solid waste collection Monday through Friday, but the definition anchors every other nighttime-noise provision in the chapter, including construction and loudspeaker hours.
Violations & Fines
Noise found unreasonably loud after factoring in nighttime timing is punishable by a forfeiture of up to $200 under § 24-146(f), enforced by Green Bay police on complaint.
