This chapter shall be known and may be cited as the "Village of Angola
Noise Law."
The purpose of this chapter is to prevent the making, creation or maintenance
of excessive, unnecessary, unnatural or unusually loud noises which are prolonged,
unusual and unnatural in their time, place and use and which are a detriment
to public health, peace, welfare, or good order.
As used in this chapter, unless the context otherwise clearly indicates,
the words and phrases used in this chapter are defined as follows:
A-BAND LEVEL
The total sound level of all noise, as measured with a sound-level
meter using the A-weighting network. The unit is the dBA.
AMBIENT NOISE
The all-encompassing noise associated with a given environment, usually
being a composite of sounds with many sources near and far.
BAND-PRESSURE LEVEL
The sound-pressure level for the sound contained within the restricted
band.
COMMERCIAL PURPOSE
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 any
such sound equipment.
CYCLE
The complete sequence of values of a periodic quantity which occurs
during a period.
DECIBEL (dB)
A unit of level which denotes the ratio between two quantities which
are proportional to power; the number of decibels corresponding to the ratio
of two amounts of power is 10 times the logarithm to the base 10 of this ratio.
EMERGENCY WORK
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.
FREQUENCY
The reciprocal of the primitive period. The unit is the cycle per
unit time and shall be specified.
MICROBAR
A unit of pressure commonly used in acoustics, equal to one dyne
per square centimeter.
MOTOR VEHICLES
Include but shall not be limited to minibikes and go-carts.
NONCOMMERCIAL PURPOSE
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
The smallest increment of time for which the function repeats itself.
PERIODIC QUANTITY
Oscillating quantity, the values of which recur for equal increments
of time.
SOUND-AMPLIFYING EQUIPMENT
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 ANALYZER
A device for measuring the band-pressure level or pressure-spectrum
level of a sound as a function of frequency.
SOUND-LEVEL METER
An instrument, including a microphone, an amplifier, an output meter,
and frequency-weighting networks for the measurement of noise and sound levels
in a specified manner.
SOUND-PRESSURE LEVEL
Twenty times the logarithm to the base 10 of the ratio of the pressure
of this sound to the reference pressure, which reference pressure shall be
explicitly stated.
SOUND TRUCK
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.
SPECTRUM
A description of its resolution into components, each of a different
frequency.
Any decibel measurement made pursuant to the provisions of this chapter
shall be based on a reference sound pressure of 0.0002 microbars, as measured
in any octave band with center frequency, in cycles per second, as follows:
63, 125, 250, 500, 1,000, 2,000, 4,000, and 8,000, or as measured with a sound-level
meter using the A-weighting.
