The sounding of any horn or other auditory signaling device on or in any motor vehicle on any public right-of-way or public space, except as a warning of danger or as provided in the Vehicle Code.
The sounding of any horn or other auditory signaling device so as to create or cause a noise disturbance.
Maximum permissible sound levels by receiving land use. With the exception of sound levels elsewhere specifically authorized or allowed in this chapter, no person shall operate or cause to be operated, make, continue or cause to be made or continued any noise or source of sound as to create a sound level which exceeds the limits set forth for the receiving land use category in Table 1 when measured at or within the property boundary of the receiving land use.
[Amended at time of adoption of Code (see Ch. 1, General Provisions, Art. I)]
Correction for character of sound. For any source of sound which emits a pure tone, the maximum sound level limits set forth in Subsection A shall be reduced by five dBA.
Measurement of sound.
Decibel measurements shall be made with a sound level meter, which shall be an instrument in good operating condition 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 an A-weighted scale and both fast and slow meter response capability.
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.
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.
Procedures and tests required by this chapter and not specified herein shall be placed on file with the Town Clerk.
Council shall have the authority, consistent with this section, to grant sound variances from this chapter after public hearing.
Any person seeking a sound variance under this section shall file an application with Council. The application shall contain information which demonstrates that bringing the source of sound or activity for which the sound variance is sought into compliance with this chapter would constitute an unreasonable hardship on the applicant, on the community or on other persons.
All applications shall be subject to a fee of $50 per day if granted and, whether granted or denied, an amount sufficient to cover the cost of advertising and notification to all residents and property owners within 100 feet of the noise source. Advertisement shall be made at least once, seven days prior to the public hearing, in a newspaper of general circulation in the Town. Notification shall be by regular mail at least seven days prior to the public hearing.
In determining whether to grant or deny an application or revoke a variance previously granted, Council shall balance hardship to the applicant, the community and other persons if the sound variance is not allowed against the adverse impact on the health, safety and welfare of persons affected, the adverse impact on property affected, and any other adverse impact, if the sound variance is allowed. Applicants for sound variances and persons contesting sound variances may be required to submit any information that Council may reasonably require. In granting or denying an application or in revoking a sound variance previously granted, Council shall place on public file a copy of the decision and the reasons for granting, denying or revoking the sound variance.
Sound variances shall be granted by notice to the applicant containing all necessary conditions, including a time limit on the permitted activity. The sound variance shall not become effective until all conditions are agreed to by the applicant. Noncompliance with any condition of the sound variance shall terminate it and subject the person holding it to those provisions of this chapter regulating the source of sound or activity for which the sound variance was granted.
Determination of modification of a granted variance shall be made in accordance with the rules and procedures set forth in the section for original applications.
Any person who shall violate any provision of this chapter shall, upon conviction thereof, be punished for each violation as provided in Chapter 1, Article II, General Penalty. The continuation of a violation of any provision of this chapter shall constitute, for each day the violation is continued, a separate and distinct violation hereunder.
