SECTION II. AMENDMENT OF ARTICLE III, "OFFENSES AGAINST PUBLIC PEACE". Section 58-56, "Unnecessary or disturbing noise" of Article III, "Offenses, Against Public Peace" of Chapter 58, "Offenses, Public Nuisances, and Miscellaneous Provisions" of Part II of the Code of Ordinances of the City of Casselberry, Florida, is hereby repealed and replaced to read as follows: Sec. 58-56. Noise control. 1. Definitions. For purposes of this Section only, the following words, terms and phrases, when used in this section, shall have the meanings ascribed to them in this section, except where the context clearly indicates a different meaning: A -weighted sound level means the sound level as measured with the A -weighting network on a sound level meter meeting the standards set forth in the American National Standards Institute (ANSI) S1.4-1983 or its successors. The unit of reporting is dBA. Sounds measured with the "A" weighting network approximate the response of human hearing when measuring sounds of low to moderate intensity without an amplified low frequency component. Ambient sound level means that measured value which represents the summation of the sound from all of the discrete sources affecting a given site ata given time, exclusive of extraneous sounds and those from the source under investigation Ambient sound level is synonymous with background sound level. Ambient sounds are differentiated from extraneous sounds by the fact that the former are of a more steady state, although they may not be continuous. Amplified sound means the reproduction of sound from any radio, stereo, CD player, DVD player, microphone, drum, turn table, audio or visual equipment, musical instrument, sound equipment, sound amplification device, television set, exterior loudspeakers, bullhorn or any similar device. Backup alarm means an audible safety device designed to alert people that a vehicle is operating in reverse, meeting Occupational Safety and Health Administration (OSHA) rules at 29 CFR Part 1926.601(b)(4) and 29 CFR Part 1026.602(a)(9), which require, in part, that: the vehicle has a reverse signal alarm audible above the surrounding noise level. C -weighted sound level is the sound level as measured using the "C" weighting network with a sound level meter meeting the standards as set forth in ANSI S1 4-1983 or its successors The unit of reporting is dBC. The "C" weighting network is more sensitive to low frequencies than the "A" weighting network. Continuous sound means any sound with a duration of more than one (1) second, as measured with a sound level meter set to the "slow" meter response Decibel means a logarithmic (dimensionless) unit of measure often used in describing the Ordinance 24-1599 Page 2 of 10
