the production of sound.
ADMINISTRATOR
The Chief of Police of the Village of Hammondsport or his
designated representative.
APPARATUS
Any mechanism which prevents, controls, detects, measures
or records the production of sound.
A-WEIGHTED SOUND LEVEL
The sound-pressure level in decibels as measured on a sound-level
meter using the A-weighting network.
CONSTRUCTION
Any activity necessary or incidental to the erection, demolition,
assembling, altering, installing or equipping of buildings, public
or private highways, roads, premises, parks, utility lines 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.
CONSTRUCTION DEVICE
Any device designed and intended for use in construction,
including but not limited to any air compressor, pile driver, manual
tool, bulldozer, pneumatic hammer, steam shovel, derrick, crane or
steam or electric hoist.
C-WEIGHTED SOUND LEVEL
The sound-pressure level in decibels as measured on a sound-level
meter using the C-weighting network. The level so read is designated
dB(C) or dBc.
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 the reference pressure, which is 20 micropascals [20 micronewtons
per square meter].
DEVICE
Any mechanism which is intended to or which actually produces
sound.
DYNAMIC INSERTION LOSS
The difference between two sound-pressure levels which are
measured at the same point in space before and after a muffler is
inserted.
EMERGENCY
Any occurrence or set of circumstances involving actual or
imminent physical trauma or property damage which demands immediate
action.
EXHAUST SOURCE
A system which removes and transports air or gas from a device.
INTERNAL-COMBUSTION ENGINE
A device for the production of mecanical energy by means
of the combustion under pressure of fossil fuel.
LAND USE DESIGNATION FOR NOISE CONTROL
The "land use designation," which shall consist of any of
the following: noise-sensitive area, Residential District, Business
and Commercial District, Light Industrial District, Medium Industrial
District and Heavy Industrial District. All land within the municipality
shall be so classified so that one of the preceeding six districts
shall apply at any given property.
MOTOR VEHICLE
Every vehicle operated or driven upon a public highway which
is propelled by any power other than muscular power, except electrically
driven invalid chairs being operated or driven by an invalid, vehicles
which run only upon rails or tracks and snowmobiles.
MUFFLER
A device consisting of a series of chambers of baffle plates
or other mechanical design for the purpose of receiving exhaust gas
from a sound source and effective in reducing sound levels.
NOISE
Any sound which annoys or disturbs humans or which causes
or tends to cause an adverse psychological or physiological effect
on humans. It is also unwanted sound or sound without value.
OCTAVE BAND
All of the components in a sound spectrum whose frequencies
are between two sine-wave components separated by an octave, with
center frequencies as specified in Table II.
OWNER
Includes the owner of the freehold of the premises or lesser
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 device or an apparatus.
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 LEVEL
A 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 the American National Standards Institute specifications
for sound-level meters (ANSI SI.4-1971 or the latest approved revision
thereof). The weighting employed must always be stated, such as 85dB(A).
The reference pressure is 0.0002 micropascal.
SOUND-LEVEL METER
An instrument, including a microphone, amplifier, output
display and frequency weighting network, for the measurement of sound
levels. "Sound-level meters" shall conform to the requirements of
the American National Standards Institute specifications for sound-level
meters: SI.11 - 1966; SI.6 - 1967; SI.8 - 1969; and SI.4 - 1971 (or
the latest approved revisions thereof).
SOUND-PRESSURE LEVEL
Twenty times the logarithm to the base 10 of the ratio of
the pressure of the sound to the reference sound pressure. Unless
otherwise specified, the effective (rms) pressure is to be utilized.
The reference sound pressure is 20 x uN/m2 (micronewtons per square meter) or 0.0002 micropascal. The "sound-pressure
level" is expressed in decibels (dB).
SOUND SIGNAL
Any sound produced by a sound-signal device designed to transmit
information.
SOUND-SIGNAL DEVICE
A device designed to produce a sound signal when operated,
including but not limited to any klaxon, air horn, whistle, bell,
gong or siren, but not an emergency signal device or verbal information.
SOUND SOURCE
Any activity or device whatsoever that produces sound.
UNNECESSARY NOISE
Any excessive or unusually loud sound or any sound which,
in the opinion of the administrator, either annoys, disturbs, injures
or endangers the comfort, repose, health, peace or safety of a person
or damages property or business. Standards to be considered in determining
whether "unnecessary noise" exists in a given situation shall include
but are not limited to the following:
(2)
The intensity of the noise.
(3)
Whether the nature of the noise is usual or
unusual.
(4)
Whether the origin of the noise is natural or
unnatural.
(5)
The volume and intensity of the background noise,
if any.
(6)
The proximity of the noise to residential sleeping
facilities.
(7)
The nature and land use designation for noise
control of the area within which the noise emanates.
(8)
The density of inhabitation of the area within
which the noise emanates.
(9)
The time of the day or night the noise occurs.
(10)
The duration of the noise.
(11)
Whether the noise is recurrent, intermittent
or constant.
(12)
Whether the noise is produced by a commercial
or non-commercial activity.
