A. 
Noise levels and guidelines.
(1) 
It shall be unlawful for any person to emit or cause to be emitted any noise beyond the boundaries of his/her/its premises in excess of the following noise levels:
Receptor
Residential Day/Night
Nonresidential Day/Night
Residential zone emitter to:
55 dbA/45 dbA
55 dbA/45 dbA
Nonresidential zone emitter to:
55 dbA/45 dbA
62 dbA/45 dbA
(2) 
Measurements shall be taken at a point that is located approximately one foot from the boundary of the emitter's premises and/or a point that is located approximately one foot within the boundary of the receptor's premises. The emitter's premises includes his/her/its individual unit of land or ground or contiguous parcels under the same ownership, as indicated by the public land records. The limitations recited above shall be determined based upon the receptor's property classification. Notwithstanding the above, the actual permitted use of the property shall control.
B. 
Impulse noise. In the case of impulse noise, the permitted noise levels, regardless of the type of emitter or receptor, shall be 100 dB peak sound-pressure level daytime and 80 dB peak sound-pressure level nighttime.
C. 
Animals. It shall be unlawful for any person to allow any animal or bird owned by him or under his control, by causing frequent or long-continued noise, to disturb the comfort or repose of any person. The residential decibel levels referred to in Subsection B above shall apply to noise caused by animals and birds.
This chapter shall not apply to noise emitted by or related to:
A. 
The unamplified human voice.
B. 
A bell or chime from any building clock, school or church.
C.

The repetition of activation of the audible signal of an intrusion alarm due to malfunction, lack of proper maintenance, or lack of reasonable care shall not be permitted hereunder.[1]

Editor's Note: See also Ch. 112, Alarm Systems.
D. 
Noises created by snow removal equipment at any time shall be exempted provided that such equipment shall be maintained in good repair so as to minimize noise, and noise discharged from exhausts shall be adequately muffled to prevent loud and/or explosive noises therefrom.
E.

F. 
Noise generated by engine-powered or motor-driven lawn care or maintenance equipment shall be exempted between the hours of 7:00 a.m. and 9:00 p.m., provided that noise discharged from exhausts is adequately muffled to prevent loud and/or explosive noises therefrom.

Instruments shall conform, at a minimum, to the standards of the American National Standards Institute for sound-level meters.
A. 
A person may apply to the First Selectman for a variance from one or more of the provisions of this chapter, provided that the applicant provides the First Selectman, or his/her designated assistant, at least 10 days prior to the proposed activity, with the following:
(1) 
The location of the proposed activity;
(2) 
Time period and hours of operation;
(3) 
Nature and intensity of anticipated noise; and
(4) 
Such other information which the First Selectman may reasonably deem necessary.
B. 
A variance may be granted if the First Selectman reasonably concludes that the noise levels will not endanger public health and compliance with this chapter would result in unreasonable hardship to the applicant. Notwithstanding the foregoing, no variance shall allow noise in violation of the State of Connecticut Department of Environmental Protection, Regulations of Connecticut State Agencies.
C. 
The First Selectman shall issue a decision, in writing, within three business days of the submission of a completed application.

A. 
All motor vehicles operated within the limits of the Town shall be subject to the noise standards and decibel levels set forth in Regulations of Connecticut State Agencies, §§ 14-80-1a through 14-80a-10a, as the same may be from time to time amended.
B. 
No sound-amplifying devices on or within motor vehicles shall emit noise in excess of the noise level specified in this chapter.
A. 
The Town's Police Department shall be responsible for investigating, and documenting through acoustic measurements, violations of this chapter. Violators may be served with an infraction notice, which shall be known as a "noise ticket." Payment of the fine prescribed by such noise ticket within the time specified thereon shall constitute a plea of nolo contendere and shall save the violator harmless from prosecution for the offense cited. Fines shall be in the amount of $60 for the first offense and $77 for each subsequent offense. Said fine amounts as may be levied may be adjusted without further municipal action so as to be in conformity with the State of Connecticut Superior Court Mail in Violations and Infraction Schedule, as it may be amended from time to time. Nothing in this chapter shall prevent the Police Department, because of the perceived nature of the offense, from proceeding not under the terms of this chapter but under the provisions of C.G.S. §§ 53a-181 and 53a-182, as they may be amended from time to time, which sections relate, generally, to breach of peace, etc. An appeal process relative to noise tickets is established below. The First Selectman shall appoint a hearing officer who shall serve at his/her discretion to hear appeals from the issuance of noise tickets. A person shall have 30 days from the date of the noise ticket to deliver a written application for a hearing. The hearing officer shall hold a hearing within five days of the receipt of the application, and his/her decision shall be final.
B. 
In accordance with § 221a-69-3.6 of the RCSA, in those individual cases where the background noise levels caused by sources not subject to this chapter exceed the standards contained herein, a source shall be considered to cause excessive noise if the noise emitted by such source exceeds the background noise level by 5 dBA, provided that no source subject to the provisions of § 250-3 shall emit noise in excess of 80 dBA at any time, and provided that this subsection does not decrease the permissible levels of the other sections of this chapter.
Any provision of this chapter held to be unconstitutional or superseded by state law or regulation shall not serve to invalidate the remaining unaffected provisions hereof. No provision of this chapter shall serve to validate any activity otherwise prohibited by state or local law or lawfully enacted zoning regulation.
This chapter shall become effective 15 days after publication thereof in a newspaper having general circulation in the Town or on the date of its approval by the Noise Control Office (or its successor agency), Division of Environmental Quality, Department of Environmental Protection of the State of Connecticut, whichever shall last occur.
