An acceptable noise complaint is any complaint made about excessive noise levels that exceed the permitted limits set by law during ‘night hours,’ which are between 11 pm and 7 am. According to these regulations, after 11 pm, the maximum allowed noise level is 34 dBA (decibels adjusted) if the background noise is no higher than 24 dBA. However, if the background noise already exceeds 24 dBA, the permitted noise level can only be 10 dBA above the background noise level.
