health, welfare, safety, and the quality of life. A substantial body
of science and technology exists by which excessive sound may be substantially
abated. The people have a right to and should be ensured an environment
free from excessive sound. It is the policy of the Town of Dalton
to prevent excessive sound that may jeopardize the health, welfare,
or safety of the citizens or degrade the quality of life.

A.
The Noise Control Officer (NCO) shall enforce the
provisions of this bylaw.
B.
The Noise Control Administrator (NCA) shall have the
power to:
(1)
Coordinate the noise control activities of all municipal
departments and cooperate with all other public bodies and agencies
to the extent practicable;
(2)
Review the actions of other municipal departments
and advise such departments to the effect, if any, of such actions
on noise control;
(3)
Review public and private projects, subject to mandatory
review or approval by other departments or boards, for compliance
with this bylaw; and
C.
All persons conducting sound measurements to assess
compliance with this section shall be trained in the current techniques
and principles of sound measurement equipment and instrumentation.
A.
All departments and agencies of the municipality shall
carry out their programs according to law and shall cooperate with
the NCA in the implementation and enforcement of this bylaw.
B.
All departments charged with new projects or changes
to existing projects that may result in the production of noise shall
consult with the NCA prior to the approval of such projects to ensure
that such activities comply with the provisions of this bylaw.
A.
Insofar as practicable, sound will be measured while
the source under investigation is operating at normal, routine conditions
and, as necessary, at other conditions, including but not limited
to design, maximum, and fluctuating rates.
B.
All tests shall be conducted in accordance with the
following procedures:
(1)
The NCO shall, to the extent practicable, identify
all sources contributing sound to the point of measurement.
(2)
Measurements shall be taken at or within the property
line of the affected person.
(3)
The measuring instrument must be calibrated using
a calibrator recommended by the measuring instrument manufacturer
before and after each series of readings.
(4)
The measuring instrument must be recertified and the
calibrator must be recalibrated at least once each year by the manufacturer
or by a person that has been approved by the manufacturer. A copy
of written documentation of such recertification and recalibration
shall be kept with the equipment to which it refers.
(5)
No outdoor measurements shall be taken:
(a)
During periods when wind speeds (including gusts)
exceed 15 miles per hour;
(b)
Without a windscreen, recommended by the measuring
instrument manufacturer, properly attached to the measuring instrument;
(c)
Under any condition that allows the measuring
instrument to become wet (e.g., rain, snow, or condensation); or
(d)
When the ambient temperature is out of the range
of the tolerance of the measuring instrument.
C.
The report for each measurement session shall include:
(1)
The date, day of the week, and times at which measurements
are taken;
(2)
The times of calibration;
(3)
The weather conditions;
(4)
The identification of all monitoring equipment by
manufacturer, model number, and serial number;
(5)
The normal operating cycle of the sources in question
with a description of the sources;
(6)
The ambient sound level, in dBA, with the sources
in question operating;
(7)
The background sound level, in dBA, without the sources
in question operating; and
(8)
A sketch of the measurement site, including measurement
locations and relevant distances, containing sufficient information
for another investigator to repeat the measurements under similar
conditions.
D.
Prior to taking noise measurements the investigator
shall explore the vicinity of the source in question to identify any
other sound sources that could affect measurements, to establish the
approximate location and character of the principal sound source,
and to select suitable locations from which to measure the sound from
the source in question.
E.
When measuring continuous sound, or sound that is
sustained for more than one second at a time, the measuring instrument
shall be set for A-weighting, slow response, and the range (if the
measuring instrument is designed to read levels over different ranges)
shall be set to that range in which the meter reads closest to the
middle of the scale. The minimum and maximum readings shall be recorded
to indicate the range of monitored values along with the central tendency
average most often displayed.
F.
The measuring instrument shall be placed at a minimum
height of three feet above the ground or from any reflective surface.
When handheld, the microphone shall be held at arm's length and pointed
at the source at the angle recommended by the measuring instrument's
manufacturer.
G.
If extraneous sound sources, such as aircraft flyovers
or barking dogs that are unrelated to the measurements increase the
monitored sound levels, the measurements should be postponed until
these extraneous sounds have become of such a level as not to increase
the monitored sound levels of interest.
H.
The monitoring session should last for a period of
time sufficient to ensure that the sound levels measured are typical
of the source in question.
I.
The background sound levels shall be subtracted from
the measured sound levels of the source of interest by using Table
1 to determine the sound levels from the source of interest alone.
If the ambient sound level is less than three dBA higher than the
background sound level, the source level cannot be derived, and a
violation of the bylaw cannot be substantiated.

A.
No person shall cause, suffer, allow, or permit the operation of any sound source on a particular category of property or any public space or right-of-way in such a manner as to create a sound level that exceeds the background sound level by at least 10 dBA during daytime hours (7:00 a.m. to 10:00 p.m.) and by at least five dBA during nighttime hours (10:00 p.m. to 7:00 a.m.) when measured at or within the real property line of the receiving property, except as provided in Subsection A(1). Such a sound source would constitute a noise disturbance.
(1)
If the background sound level cannot be determined,
the absolute sound level limits set forth in Table 2 shall be used.
(2)
If the sound source in question is a pure tone, the
limits of Table 2 shall be reduced by five dBA.

of any violations of the bylaw and, having determined that such violations
have occurred or are continuing to occur, shall serve a written notice
of violation on the offender. Every day that the violation continues
after service of a notice of violation may constitute a separate violation
for which additional notices of violation are not required.
B.
A notice of violation is deemed served on the day
it is received, if served by hand or by certified mail, return receipt
requested, and is deemed served on the third day after mailing, if
served by first-class mail, postage prepaid.
C.
Each notice of violation shall state that the NCA
shall hold a public hearing, at which the offender shall be allowed
to appear and present evidence in his behalf, to determine if the
violation(s) set forth in the notice constitutes a violation of the
bylaw, and to impose any and all appropriate penalties for such violations,
including fines as set forth below, and/or an order to cease and desist.
Notice of such public hearing shall be served on the offender in the
manner set forth for the above service of a notice of violation, such
hearing to be held no sooner than two weeks from the date that such
notice is served.
D.
If a person has been found by the NCA to have violated
this bylaw, and has been ordered to cease and desist such violation,
and is subsequently determined by the NCA to have again committed
that same violation, then the violator shall, in addition to the penalty
and enforcement provisions set forth in this section, pay to the Town
the reasonable cost of testing incurred by the Town to determine such
subsequent violation(s).
If any provision of this bylaw is held to be
unconstitutional, preempted by federal or state law, or otherwise
invalid by any court of competent jurisdiction, the remaining provisions
of the bylaw shall not be invalidated.
This bylaw shall take effect upon its approval
by the Attorney General of the Commonwealth of Massachusetts, and
is posted and published by the Town Clerk of Dalton, Massachusetts
in accordance with MGL c. 40, § 32; and is intended to apply
to all preexisting noise pollution as of that date.
