As used in this chapter, the following terms shall have
the meanings indicated:
AMBIENT NOISE
The all-encompassing noise associated with a given environment, being
usually a composite of sounds from many sources.
A-WEIGHTED SOUND LEVEL
The sound pressure level in decibels as measured on a sound level
meter using the A-weighted network. The level so read is designated "dBA."
CONSTRUCTION
Any activity necessary or incidental to erection, demolition, assembling,
altering, installing or equipping of buildings, public or private highways,
roads, premises, parks, utility lanes or other property, including but not
limited to related activities such as land clearing, grading, earthmoving,
excavating, blasting, filling and landscaping, but not including agriculture.
DBA
The abbreviation designating the unit of sound level as measured
by a sound level meter using the A-weighting, also known as "dba" or "dBA."
DECIBEL
The practical unit of measurement for sound pressure level; the number
of decibels of a measured sound is equal to 20 times the logarithm to the
base 10 of the ratio of the sound pressure of the measured sound to the sound
pressure of a standard sound (20 micropascals); abbreviated "db."
DEMOLITION
Any dismantling, intentional destruction, or removal of buildings
or structures.
EMERGENCY
Any occurrence or circumstances involving actual or imminent physical
or property damage, which demands immediate action.
EMERGENCY WORK
Any work or action necessary to deliver essential services, including,
but not limited to, repairing water, gas, electricity, telephone, sewer facilities,
or public transportation facilities, removing fallen trees on public rights-of-way,
dredging of waterways or abating life-threatening conditions.
FREQUENCY
The number of sound pressure oscillations per second, expressed in
hertz; abbreviated "Hz."
IMPULSE SOUND
Sound characterized by either a single pressure peak or a single
burst (multiple pressure peaks) having a duration of less than one second.
NOISE
Any sounds of such level and duration as to be or tend to be injurious
to human health or welfare, or which would unreasonably interfere with the
enjoyment of life or property throughout the Village.
NOISE DISTURBANCE
Any sound which:
(1)
Endangers or injures the safety or health of humans or animals; or
(2)
Annoys or disturbs a reasonable person of normal sensitivities; or
(3)
Endangers or injures personal or real property.
PEAK SOUND PRESSURE LEVEL
The maximum absolute value of the instantaneous sound pressure level
during a specified time interval.
PERSON
Any individual, association, partnership, corporation or other entity,
and includes any officer, employee, department or agency of the above.
PUBLIC RIGHT-OF-WAY
Any street, avenue, boulevard, road, highway, sidewalk, alley or
boardwalk that is leased, owned or controlled by a government entity, no matter
how designated.
PUBLIC SERVICE FACILITY
Any facility and its related premises, property, or equipment used
to provide governmental services to the public including, but not limited
to:
(2)
Offices and buildings of agencies or instrumentalities of government;
PUBLIC SERVICE INDUSTRIAL FACILITY
Any facility and its related premises, property, or equipment used
to provide industrial governmental services to the public, including, but
not limited to:
(1)
Waste collection and disposal centers;
(3)
Water and sewage facilities.
PUBLIC SPACE
Any real property or structures thereon that are owned, leased, or
controlled by a governmental entity.
REAL PROPERTY LINE
Either the imaginary line including its vertical extension, that
separates one parcel of real property from another, or the vertical and horizontal
boundaries of a dwelling unit that is one in a multi-dwelling-unit building.
SOUND
An oscillation in pressure, partial displacement, particle velocity
or other physical parameter, in a medium with internal forces that causes
compression and rarefaction of that medium. The description of sound may include
any characteristic of such sound, including duration, intensity and frequency.
SOUND LEVEL
The weighted sound pressure level obtained by the use of a sound
level meter and frequency weighting network, such as A, B, C as specified
in American National Standards Institute specifications for sound level meters
(ANSI). If the frequency weighting employed is not indicated, the A-weighting
shall apply.
SOUND LEVEL METER
Any instrument, including a microphone, amplifier, an output meter
and frequency weighting networks, for the measurement of noise and sound levels
in a specific manner and which complies with standards established by the
American National Standards Institute (ANSI) specifications for sound level
meters.
SOUND PRESSURE LEVEL
The level of a sound measured in dB units with a sound level meter,
which has a uniform ("flat") response over the band of frequencies measured.
SOUND SOURCE
Any person, animal, device, operation, process, activity, or phenomenon,
which emits or causes sound.
VIBRATION
An oscillatory motion of solid bodies of deterministic or random
natures described by displacement, velocity or acceleration with respect to
a given reference point.
