As used in this chapter, the following terms shall have the meanings
as indicated:
DECIBEL (DB)
A unit for measuring the amplitude of sound, equal to 20
times the logarithm to the base 10 of the ratio of the pressure of
the sound measured to the reference pressure, which is 20 micropascals.
EMERGENCY
Any occurrence or set of circumstances involving actual or
imminent physical trauma, or property damage which requires immediate
action.
IMPULSIVE SOUND
Sound of short duration, usually less than one second, with
an abrupt onset and rapid decay. Examples of impulsive sounds include
explosions, drop impacts and firearm discharges.
MOTOR VEHICLE
Every vehicle which is not self-propelled, except an electrically
driven invalid chair being operated or driven by an invalid, which
includes but is not limited to a passenger vehicle, truck, truck-trailer,
trailer or semitrailer, motorcycle, snowmobile, minibike and Go-Kart.
MULTIFAMILY DWELLING
Any housing unit where two or more dwellings are separated
by a common wall, floor, or ceiling, including but not limited to
apartments, condominiums and townhouses.
NOISE LEVEL
The amplitude of sound pressure referenced to 20 micropascals,
measured in decibels, using the A-weighting network (for the purposes
of this chapter).
NOISE LEVEL MEASUREMENT
The procedure of measuring sound consisting of the usage
of a precision sound level meter (SLM), as defined in this section,
set to "fast" response. If the sound level meter is analog with a
VU meter, then the response shall be "slow" unless the noise issue
is impulsive. The meter must be calibrated before any measurements
and the microphone shall be a minimum of 3 1/2 feet from any
wall, floor or other large sound-reflecting surface. The meter shall
be protected from wind or other extraneous noise by the use of screens,
shields or other appropriate devices.
OWNER
Includes the owner of the freehold of the premises or lessor
estate therein; or mortgagee thereof, a lessee or agent of any of
the above persons, a lessee of a device or his agent, a tenant, operator
or any other person who has regular control of a building, device
or an apparatus.
PERSON
Any individual, association, partnership or corporation,
including any officer, employee, department, agency or instrumentality
of the state or any political subdivision of a state.
PRECISION SOUND LEVEL METER
A sound pressure level measuring instrument which conforms
to the American National Standards Institute (ANSI) specification
S1.4 for Type 1 or Type 2 measuring instruments.
REAL PROPERTY BOUNDARY
A line along the ground surface and its vertical extension,
which separates the real property owned by one person from that owned
by another person.
RESIDENTIAL PROPERTY
Any property legally used for a single-family, two-family
or multifamily dwelling as defined in the Zoning Chapter.
SOUND DEVICE OR APPARATUS
Any apparatus or device for the making, reproduction or amplification
of the human voice or other sounds.
