GENERAL REFERENCES
Alarms — See Ch. 83.
Nuisances — See Ch. 260.
The Portsmouth Town Council hereby finds and declares that:
A. 
Excessive noise is a serious hazard to the public health and welfare and the quality of life.
B. 
A substantial body of science and technology exists by which excessive noise can be substantially abated without serious inconvenience to the public.
C. 
Certain of the noise-producing equipment in this community is essential to the quality of life herein and should be allowed to continue at reasonable levels with moderate regulation.
D. 
Each person has a right to an environment reasonably free from noise which jeopardizes health or welfare or unnecessarily degrades the quality of life.
E. 
It is declared policy of the Town to promote an environment free from excessive noise, otherwise properly called "noise pollution," which unnecessarily jeopardizes the health and welfare and degrades the quality of the lives of the residents of this community, without unduly prohibiting, limiting or otherwise regulating the function of certain noise-producing equipment which is not amenable to such controls and yet is essential to the quality of life in the community.
A. 
The purpose of this chapter is to establish standards for the control of noise pollution in the Town by setting maximum permissible sound levels for various activities to protect the public health, safety and general welfare.
B. 
This chapter may be cited as the "Noise Abatement Ordinance" of the Town.
C. 
This chapter shall apply to the control of all noise originating within the limits of the Town or originating from properties lying outside the limits of the Town owned or controlled by the Town, except where either:
(1) 
A state or federal agency has adopted a different standard or rule than that prescribed in this chapter and has so preempted the regulation of noise from a particular source as to render this chapter inapplicable thereto; or
(2) 
The Council has determined that, by reason of public acceptance of the activity producing a particular noise, such noise is deemed acceptable to the residents of the Town.
A. 
If the measurements of sound are made with a sound-level meter, it shall be an instrument in good operating condition and meeting the requirements of a Type I or Type II meter, as specified by ANSI Standard 1.4-1971. For purposes of this chapter, a sound-level meter shall contain at least an A-weighted scale and both fast and slow meter response capability.
B. 
If the measurements are made with other instruments, the procedure shall be carried out in such a manner that the overall accuracy is at least that called for in ANSI Standard 1.4-1971 for Type II instruments.
C. 
When the location or distance prescribed in this chapter for measurement of sound is impractical or would provide misleading or inaccurate results, measurements may be taken at other locations or distances using appropriate correction factors specified in this chapter.
D. 
Procedures and tests required by this chapter and not specified herein shall be placed on file with the Town Clerk.
Unless otherwise expressly stated or the context clearly indicates a different intention, the following words and terms shall have the meanings given. Definitions of technical terms used in this chapter, which are not herein defined, shall be obtained from publications of acoustical terminology issued by ANSI or its successor body.
