Definitions. As used in this section, the following
terms shall have the meanings indicated:
AMBIENT NOISE
The all-encompassing noise associated with a given environment,
usually being a composite of sounds with many sources near and far,
but excluding the noise source being measured.
A-WEIGHTED SOUND LEVEL
The sound-pressure level in decibels as measured on a sound-level
meter using A-weighting network. The level so read is designated dB(A)
or dBA.
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 equipment.
CONSTRUCTION
Any site preparation, assembly, erection, substantial repair,
alteration, or similar action, but excluding demolition, for or of
public or private rights-of-way, structures, utilities or similar
property.
CYCLE
The complete sequence of values of a periodic quantity which
occurs during a period.
DAYTIME
The hours from 7:00 a.m. to 10:00 p.m.
DECIBEL (dB)
A unit for measuring the volume of a sound, equal to 20 times
the logarithm to the base 10 of the ratio of the pressure of the sound
measured to reference pressure, which is 20 micropascals (20 micronewtons
per square meter).
DEMOLITION
The dismantling, intentional destruction or removal of structures,
utilities, public or private right-of-way surfaces, or similar property.
EMERGENCY
Any occurrence or set of circumstances involving actual or
imminent physical trauma or property damage which demands immediate
action.
EMERGENCY WORK
Any work performed for the purpose of preventing or alleviating
the physical trauma or property damage threatened or caused by an
emergency.
FREQUENCY
The frequency of a function periodic in time is the reciprocal
of the primitive period. The unit is the cycle per unit time and shall
be specified as cycles per second unless another unit of time is more
convenient in a particular case.
IMPULSIVE SOUND
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.
MICROBAR
A unit of pressure commonly used in acoustics and is equal
to one dyne per square centimeter.
MOTOR VEHICLE
Has the same definition as that term is defined by Ch.
340, Wis. Stats.
NIGHTTIME
The hours of 10:00 p.m. until 7:00 a.m. of the following
day.
NOISE
Any sound which is unnecessary, excessive, unnatural, annoying,
prolonged or unusually loud in relationship to its time, place and
use effect.
NOISE DISTURBANCE
Any sound which:
(1)
Endangers or injures the safety or health of
humans or animals;
(2)
Annoys or disturbs a reasonable person of normal
sensitivities; or
(3)
Endangers or injures personal or real property.
NONCOMMERCIAL PURPOSE
The use, operation, or maintenance of any sound-amplifying
equipment for other than a commercial purpose. "Noncommercial purpose"
shall mean and include, but shall not be limited to, philanthropic,
political, patriotic, and charitable purpose.
PERIOD
The period of a periodic quantity is 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.
PERSON
Any individual, association, partnership, or corporation,
and includes any officer, employee, department, agency or instrumentality
of a state or any political subdivision of a state.
POWERED MODEL VEHICLE
Any self-propelled airborne, waterborne, or landborne plane,
vessel or vehicle which is not designed to carry persons, including
but not limited to any model airplane, boat, car, or rocket.
PUBLIC RIGHT-OF-WAY
Any street, avenue, boulevard, highway, sidewalk or alley
or similar place designated a public right-of-way by the Tribe.
PUBLIC SPACE
Any real property or structures thereon which are designated
public space by the Tribe.
PURE TONE
Any sound which can be distinctly heard as a single pitch
or a set of single pitches. For the purpose of this section, a pure
tone shall exist if the one-third octave band sound-pressure level
in the band with the tone exceeds the arithmetic average of the sound-pressure
levels of the two contiguous one-third octave bands by five dB for
center frequencies of 500 Hz and above and by eight dB for center
frequencies between 180 and 400 Hz and by 15 dB for center frequencies
less than or equal to 125 Hz.
REAL PROPERTY BOUNDARY
An imaginary line along the ground surface, and its vertical
extension, which separate the real property owned by one person from
that owned by another person, but not including intra-building real
property divisions.
SOUND
An oscillation in pressure, particle displacement, particle
velocity or other physical parameter, in a medium with internal forces
that cause compression and rarefaction of that medium. The description
of sound may include any characteristic of such sound, including duration,
intensity and frequency.
SOUND-AMPLIFYING EQUIPMENT
Any machine or device for the amplification of the human
voice, music, or any other sound, but shall not include standard automobile
radios when used and heard only by the occupants of the vehicle in
which the automobile radio is installed, and as used in this section
shall not include warning devices on authorizing emergency vehicles
used only for traffic safety, law enforcement, or authorized emergency
purposes.
SOUND LEVEL
The weighted sound-pressure level obtained by the use of
a sound-level meter and frequency weighting network, such as A, B,
or C, as specified in American National Standards Institute specifications
for sound-level meters (ANSI S1.4-1971 or the latest approved revision
thereof). If the frequency weighting employed is not indicated, the
A-weighting shall apply.
SOUND-LEVEL METER
An instrument which includes a microphone, amplifier, RMS
detector, integrator or time averager, output meter, and weighting
networks used to measure sound-pressure levels.
SOUND PRESSURE
The instantaneous difference between the actual pressure
and the average or barometric pressure at a given point in space,
as produced by sound.
SOUND-PRESSURE LEVEL
Twenty times the logarithm to the base 10 of the ratio of
the RMS sound pressure to the reference pressure of 20 micropascals
(20 x 10-6 N/m2). The sound-pressure level is denoted Lp or SPL and
is expressed in decibels.
SOUND TRUCK
Any vehicle, regardless of motive power, whether in motion
or stationary, having mounted thereon, or attached thereto, any sound-amplifying
equipment.
WEEKDAY
Any day Monday through Friday which is not a legal holiday.
