meaning given them in the Act:
(a) Act means the Noise Control Act of 1972 (Pub. L. 92-574, 86
Stat. 1234).
(b) Car Coupling Sound means a sound which is heard and identified

level meter indicator (FAST) to register an increase of at least ten
decibels above the level observed immediately before hearing the sound.
(c) Carrier means a common carrier by railroad, or partly by
railroad and partly by water, within the continental United States,
subject to the Interstate Commerce Act, as amended, excluding street,
suburban, and interurban electric railways unless operated as a part of
a general railroad system of transportation.
(d) Classification of Railroads means the division of railroad
industry operating companies by the Interstate Commerce Commission into
three categories. As of 1978, Class I railroads must have annual
revenues of $50 million or greater, Class II railroads must have annual
revenues of between $10 and $50 million, and Class III railroads must
have less than $10 million in annual revenues.
(e) Commercial Property means any property that is normally
accessible to the public and that is used for any of the purposes
described in the following standard land use codes (reference Standard
Land Use Coding Manual. U.S. DOT/FHWA, reprinted March 1977): 53-59,

(f) dB(A) is an abbreviation meaning A-weighted sound level in
decibels, reference: 20 micropascals.
(g) Day-night Sound Level means the 24-hour time of day weighted
equivalent sound level, in decibels, for any continuous 24-hour period,
obtained after addition of ten decibels to sound levels produced in the
hours from 10 p.m. to 7 a.m. (2200-0700). It is abbreviated as
Ldn.
(h) Decibel means the unit measure of sound level, abbreviated as
dB.
(i) Energy Average Level means a quantity calculated by taking ten
times the common logarithm of the arithmetic average of the antilogs of
one-tenth of each of the levels being averaged. The levels may be of any
consistent type, e.g. maximum sound levels, sound exposure levels, and
day-night sound levels.
(j) Energy Summation of Levels means a quantity calculated by taking
ten times the common logarithm of the sum of the antilogs of one-tenth
of each of the levels being summed. The levels may be of any consistent
type, e.g., day-night sound level or equivalent sound level.
(k) Equivalent Sound Level means the level, in decibels, of the
mean-square A-weighted sound pressure during a stated time period, with
reference to the square of the standard reference sound pressure of 20
micropascals. It is the level of the sound exposure divided by the time
period and is abbreviated as Leq.
(l) Fast Meter Response means that the ``fast'' response of the
sound level meter shall be used. The fast dynamic response shall comply
with the meter dynamic characteristics in paragraph 5.3 of the American
National Standard Specification for Sound Level Meters. ANSI S1.4-1971.
This publication is available from the American National Standards
Institute, Inc., 1430 Broadway, New York, New York 10018.
(m) Idle means that condition where all engines capable of providing
motive power to the locomotive are set at the lowest operating throttle
position; and where all auxiliary non-motive power engines are not
operating.
(n) Interstate Commerce means the commerce between any place in a
State and any place in another State, or between places in the same
State through another State, whether such commerce moves wholly by rail
or partly by rail and partly by motor vehicle, express, or water. This
definition of ``interstate commerce'' for purposes of this regulation is
similar to the definition of ``interstate commerce'' in section 203(a)
of the Interstate Commerce Act (49 U.S.C. 303(a)).
(o) Load Cell means a device external to the locomotive, of high
electrical resistance, used in locomotive testing to simulate engine
loading while the locomotive is stationary. (Electrical energy produced
by the diesel generator is dissipated in the load cell resistors instead
of the traction motors).
(p) Locomotive means for the purpose of this regulation, a self-
propelled vehicle designed for and used on railroad tracks in the
transport or rail cars, including self-propelled rail passenger
vehicles.
(q) Locomotive Load Cell Test Stand means the load cell Sec.
201.1(o) and associated structure, equipment, trackage and locomotive
being tested.
(r) Maximum Sound Level means the greatest A-weighted sound level in
decibels measured during the designated time interval or during the
event, with either fast meter response Sec. 201.1(l) or slow meter
response Sec. 201.1(ii) as specified. It is abbreviated as
Lmax.
(s) Measurement Period means a continuous period of time during
which noise of railroad yard operations is assessed, the beginning and
finishing times of which may be selected after completion of the
measurements.
(t) Rail Car means a non-self-propelled vehicle designed for and
used on railroad tracks.
(u) Railroad means all the roads in use by any common carrier
operating a railroad, whether owned or operated under a contract,
agreement, or lease.
(v) Receiving Property Measurement Location means a location on
receiving property that is on or beyond the railroad facility boundary
and that meets the receiving property measurement location criteria of
subpart C.
[[Page 71]]
(w) Receiving Property means any residential or commercial property
that receives the sound from railroad facility operations, but that is
not owned or operated by a railroad; except that occupied residences
located on property owned or controlled by the railroad are included in
the definition of ``receiving property.'' For purposes of this
definition railroad crew sleeping quarters located on property owned or
controlled by the railroad are not considered as residences. If,
subsequent to the publication date of these regulations, the use of any
property that is currently not applicable to this regulation changes,
and it is newly classified as either residential or commercial, it is
not receiving property until four years have elapsed from the date of
the actual change in use.
(x) Residential Property means any property that is used for any of
the purposes described in the following standard land use codes (ref.
Standard Land Use Coding Manual. U.S. DOT/FHWA Washington, DC, reprinted
March 1977): 1, Residential: 651, Medical and other Health Services; 68,
Educational Services; 691, Religious Activities; and 711, Cultural
Activities.
(y) Retarder (Active) means a device or system for decelerating
rolling rail cars and controlling the degree of deceleration on a car by
car basis.
(z) Retarder Sound means a sound which is heard and identified by
the observer as that of a retarder, and that causes a sound level meter
indicator at fast meter response Sec. 201.1(l) to register an increase
of at least ten decibels above the level observed immediately before
hearing the sound.
(aa) Sound Level means the level, in decibels, measured by
instrumentation which satisfies the requirements of American National
Standard Specification for Sound Level Meters S1.4-1971 Type 1 (or S1A)
or Type 2 if adjusted as shown in Table 1. This publication is available
from the American National Standards Institute, Inc., 1430 Broadway, New
York, New York 10018. For the purpose of these procedures the sound
level is to be measured using the Aweighting of spectrum and either the
FAST or SLOW dynamic averaging characteristics, as designated. It is
abbreviated as LA.
(bb) Sound Exposure Level means the level in decibels calculated as
ten times the common logarithm of time integral of squared A-weighted
sound pressure over a given time period or event divided by the square
of the standard reference sound pressure of 20 micropascals and a
reference duration of one second.
(cc) Sound Pressure Level (in stated frequency band) means the
level, in decibels, calculated as 20 times the common logarithm of the
ratio of a sound pressure to the reference sound pressure of 20
micropascals.
(dd) Special Purpose Equipment means maintenance-of-way equipment
which may be located on or operated from rail cars including: Ballast
cribbing machines, ballast regulators, conditioners and scarifiers, bolt
machines, brush cutters, compactors, concrete mixers, cranes and
derricks, earth boring machines, electric welding machines, grinders,
grouters, pile drivers, rail heaters, rail layers, sandblasters, snow
plows, spike drivers, sprayers and other types of such maintenance-of-
way equipment.
(ee) Special Track Work means track other than normal tie and
ballast bolted or welded rail or containing devices such as retarders or
switching mechanisms.

exceeded in a stated percentage (x) of the duration of the measurement
period. It is abbreviated as Lx.
(gg) Switcher Locomotive means any locomotive designated as a
switcher by the builder or reported to the ICC as a switcher by the
operator-owning-railroad and including, but not limited to, all
locomotives of the builder/model designations listed in Appendix A to
this subpart.
(hh) Warning Device means a sound emitting device used to alert and
warn people of the presence of railroad equipment.
(ii) Slow Meter Response means that the slow response of the sound
level meter shall be used. The slow dynamic response shall comply with
the meter dynamic characteristics in paragraph 5.4 of the American
National Standard Specification for Sound Level Meters. ANSI S1.4-1971.
