For the purposes of this chapter, unless otherwise apparent from the context, certain words and phrases used in this chapter are defined as set forth in Section 8.22.022 of this article.
(Ord. 90-03 §1, 1990)
shall mean the sound level in decibels as measured on a sound level meter using the A-weighting network weighted to the range of human hearing. The level so read is designated dB(a) or dBA.
means all-encompassing noise associated with a given environment, being usually a composite of sounds from many sources near and far. For the purposes of this chapter, the ambient noise level is the level obtained when the noise level is averaged over a period of fifteen minutes without the inclusion of noise from isolated identifiable sources, at the location and time of day near that at which a comparison is to be made.
means any commercial area as defined in the general plan and Zoning provisions and designated by a "C" or "P-C" or "H-1" prefix in the zoning provisions and on the zoning map.
means any site preparation, assembly, erection, substantial repair, alteration, or similar action for or on public or private rights-of-way, structures, utilities, or similar property.
means any additive period of time composed of individual time segments which may be continuous or interrupted.
means a unit for measuring the amplitude of a sound, equal to twenty times the logarithm to the base ten of the ratio of the pressure of the sound measured to the reference pressure, which is twenty microPascals.
means work or action made necessary to restore property to a safe condition after a public calamity, or work required to protect persons or property from imminent exposure to danger of damage, or work by public or private utilities to restore utility service.
means a stationary device which creates sounds while fixed or motionless, including, but not limited to, residential, agricultural, industrial, and commercial machinery and equipment, pumps, fans, compressors, air-conditioners, and refrigeration equipment.
means sound of short duration, usually less than one second, with an abrupt onset and rapid decay. Examples of sources of impulsive sound include explosions, drop forge impacts, and the discharge of firearms.
means any industrial area as defined by the general plan and zoning provisions and designated by an "M" or "L-M" prefix in the zoning provisions and on the zoning map.
means that noise which intrudes over and above the existing ambient noise at a given location. The relative intrusiveness of a sound depends upon its amplitude, duration, frequency and time of occurrence, and tonal or informational content, as well as the prevailing ambient noise level.
means the possession of a formal license or a permit issued by the appropriate jurisdictional authority or, where no permits or licenses are issued, the sanctioning of the activity by the jurisdiction as noted in public records.
means any noise source other than a fixed noise source.
means and includes any and all self-propelled vehicles as defined in the Vehicle Code of the state, including all on-highway type motor vehicles subject to registration under said Code and all off-highway type motor vehicles subject to identification under said Code.
means a device consisting of a series of chambers or baffle plates, or other mechanical design, for the purpose of receiving exhaust gas from an internal combustion engine and effective in reducing noise.
means the city manager or his or her representative. The noise control officer shall be empowered to enforce the provisions of this chapter.
means any sound which:
means A-weighted sound pressure level in decibels obtained by using a sound level meter at slow response with a reference pressure of twenty microPascals. The unit of measurement shall be designated as dBA.
means any area so designated for the purpose of ensuring exceptional quiet, for example, a hospital zone, nursing home, or family care home when specifically designated as such.
means any defined area or region of a generally consistent land use wherein the ambient noise levels are within a range of five dBA.
means a person, firm, association, partnership, joint venture, corporation, or any entity, public or private in nature.
means any street, avenue, boulevard, highway, sidewalk, alley, or similar place which is owned or controlled by a governmental entity.
means any real property, or structure thereon, which is owned or controlled by a governmental entity.
means any sound which can be judged as audible by the noise control officer as a single pitch or a set of single pitches.
means an imaginary line along the ground surface, and its vertical ex-tension, which separates the real property owned by one person from that owned by another person, but not including intra-building real property divisions.
means any residential area as defined in the General Plan and Zoning provisions and designated by an "R" or "P-C" when the use is residential or "T" prefix in the Zoning provisions and on the Zoning map.
means any device for the amplification of the human voice, music, or any other sound, excluding standard automobile radios when used and heard only by the occupants of the vehicle in which the radio is installed, and, as used in this chapter, warning devices on authorized emergency vehicles or horns or other warning devices on any vehicle used only for traffic safety purposes.
means an instrument, including a microphone, an amplifier, an output meter, and frequency weighting networks for the measurement of sound levels, which meets or exceeds the requirements pertinent for type S1A meters in the American National Standards Institute Specifications for sound level meters, S1.4-1971, or the most recent revision thereof.
means any motor vehicle, regardless of motive power, whether in motion or stationary, having mounted thereon or attached thereto any sound amplifying equipment.
means the minimum ground-or structure-borne vibrational motion necessary to cause a normal person to be aware of the vibration by such direct means as, but not limited to, sensation by touch or the visual observation of moving objects. The perception threshold shall be presumed to be a motion velocity of .005 in/sec over the range of one to one hundred Hertz.
means any of the zones specified in this code as such zones are presently identified there and as they may be subsequently modified or altered.
