Excessive noise is a serious hazard to the public health, welfare,
safety and the quality of life. Community members have a right to,
and should be ensured of, an environment free from excessive noise.
Therefore, it is the policy of Laguna Beach to prevent excessive noise
that may jeopardize the health, welfare or safety of the citizens
or degrade their quality of life.
(Ord. 1448 § 1, 2005)
The following words and terms, when used in this chapter, shall
have the following meanings:
"Ambient noise level"
means the all-encompassing noise level associated with a
given environment and is a composite of sounds from all sources, excluding
the alleged offensive noise or excessive sound, at the location and
approximate time at which a comparison with the alleged offensive
noise is to be made.
"Applicable (noise) zone"
means the noise zone category based on the actual use of
the property, provided that the actual use is a legal use in the city
of Laguna Beach.
"A-weighted sound level"
means the sound pressure level in decibels (dBAs) as measured
with a sound level meter using the A-weighted filter network (scale)
at slow response and at a pressure of twenty microPascals. The A-weighted
filter de-emphasizes the very low and a very high frequency component
of sound in a manner similar to the response of the human ear, and
is a numerical method of rating human judgment of loudness.
"Decibel (dBA)"
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 of twenty
microPascals.
"Equivalent sound or noise level (Leq)"
means the International Electrotechnical Commission (IEC)
60804 Standard for measurement, or the most recent revision thereof,
for the sound level corresponding to a steady state noise level over
a given sample period with the same amount of acoustic energy as the
actual time varying noise level or the energy average noise level
during the sample period. The measurement period for the purposes
of this chapter is fifteen minutes.
"Impulsive noise"
means a noise of short duration usually less than one second
and of high intensity, with an abrupt onset and rapid decay. Such
objectionable noises may also be repetitive.
"Intrusive noise"
means that noise which intrudes over and above the ambient
noise at a given location. The relative intrusiveness of a sound depends
upon its amplitude, duration, frequency, time of occurrence and tonal
or information content, as well as the prevailing ambient noise level.
"Maintenance"
means the upkeep, repair or preservation of existing property
or structures.
"Noise"
means any unwanted sound or sound which is undesirable because
it interferes with speech and hearing, or is intense enough to damage
hearing or is otherwise annoying. The State Noise Control Act defines
noise as "...excessive undesirable sound..."
"Noise level (sound level)"
means the weighted sound pressure level obtained by use of
a sound level meter having a standard frequency filter for attenuating
part of the sound spectrum. For purposes of this chapter, all noise
levels (sound levels) shall be A-weighted sound pressure level.
"Noise (sound) level meter"
means an instrument, including a microphone, an amplifier,
an output meter and frequency weighting networks for the measurement
and determination of noise and sound levels. For the purposes of this
chapter the sound level meter must meet the International Electrotechnical
Commission (IEC) 60651 and 60804 Standards, or the most recent revisions
thereof, for Type 1 sound level meters or an instrument and the associated
recording and analyzing equipment which will provide equivalent data.
(Ord. 1448 § 1, 2005)
The properties hereinafter described shall be assigned to the
