It is declared to be the policy of the city to prohibit unnecessary,
excessive, and annoying noises from all sources subject to its police
power. At certain levels noises are detrimental to the health and
welfare of the citizenry and in the public interests shall be systematically
proscribed.
(Prior code § 99.01)
For the purpose of this chapter, the following definitions shall
apply unless the context clearly indicates or requires a different
meaning.
"Ambient noise"
means the 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, ambient noise level
is the level obtained when the noise level is averaged over a period
of 15 minutes without inclusion of noise from isolated identifiable
sources, at the location and time of day near that at which a comparison
is to be made.
"Clearly audible"
means can be heard by any person of average or normal hearing
capability.
"Commercial purpose"
shall mean and include the use, operation or maintenance
of any sound amplifying equipment for the purpose of advertising any
business, or any goods, or any services, or for the purpose of attracting
the attention of the public to, or advertising for, or soliciting
patronage or customers to or for any performance, show, entertainment,
exhibition or event, or for the purpose of demonstrating such sound
equipment.
"Decibel"
means a unit of level when the base of the logarithm is the
tenth root of 10 and the quantities concerned are proportional to
power.
"Emergency work"
means work made necessary to restore property to a safe condition
following a public calamity or work required to protect persons or
property from an imminent exposure to danger or work by private or
public utilities when restoring utility service.
"Frequency"
of a function periodic in time shall mean the reciprocal
of the primitive period. The unit is the hertz and shall be specified.
"Hertz"
means the complete sequence of values of a periodic quantity
which occurs during a period.
"Microbar"
means a unit of pressure commonly used in acoustics and equal
to one dyne per square centimeter.
"Motor vehicles"
means any and all self-propelled vehicles as defined in the
California
Vehicle Code, specifically including, but not limited to,
mini-bikes and go-carts.
"Noncommercial purpose"
means the use, operation or maintenance of any sound equipment
for other than a commercial purpose. "Noncommercial purpose" shall
mean and include, but shall not be limited to, philanthropic, political,
patriotic and charitable purposes.
"Period"
of a periodic quantity shall mean the smallest increment
of time for which the function repeats itself.
"Periodic quantity"
means oscillating quantity, the values of which recur for
equal increments of time.
"Person"
means a person, firm, association, copartnership, joint venture,
corporation, or any entity, public or private in nature.
"Sound amplifying equipment"
means any machine or device for the amplification of the
human voice, music, or any other sound. Sound amplifying equipment
shall not include standard automobile radios when used and heard only
by the occupants of the vehicle in which the automobile radio is installed.
Sound amplifying equipment, as used in this chapter, shall not include
warning devices on authorized emergency vehicles or horns or other
warning devices on any vehicle used only for traffic safety purposes.
"Sound level"
(noise level), in decibels (dB) is the sound measured with
the A weighting and slow response by a sound level meter.
"Sound level meter"
means an instrument including a microphone, an amplifier,
an output meter, and frequency weighting networks for the measurement
of sound levels which satisfies the pertinent requirements in American
Standards Specifications for sound level meters SI.4-1971 or the most
recent revision thereof.
"Sound truck"
means any motor vehicle, or any other vehicle regardless
of motive power, whether in motion or stationary, having mounted thereon,
or attached thereto, any sound amplifying equipment.
(Prior code § 99.02)
Any sound level measurement made pursuant to the provisions
of this chapter shall be measured with a sound level meter using the
A weighting.
(Prior code § 99.03)
Where the ambient noise level is less than designated in this
section the respective noise level in this section shall govern.
