§ 204-6. Maximum permissible sound levels.

A. 

No person shall cause, suffer, allow, or permit the operation of any source of sound on any source property listed in § 204-1A(1) above in such a manner as to create a sound level that equals or exceeds the sound level limits set forth in Tables I and II in § 204-7 when measured at or within the real property line of any of the receiving properties listed in Tables I and II, except as specified in Subsection B below.

B. 

When measuring total sound or residual sound within a multiuse property, or within a residential unit when the property line between it and the source property is a common wall, all exterior doors and windows shall be closed and the measurements shall be taken in the center of the room most affected by the noise. Residual sound shall be measured in accordance with N.J.A.C. 7:29-2.9(b)2. When measuring total sound or residual sound, all sound sources within the dwelling unit must be shut off (e.g., television, stereo). Measurements shall not be taken in areas which receive only casual use such as hallways, closets, and bathrooms.

C. 

Indoor measurements shall only be taken if the sound source is on or within the same property as the receiving property, as in the case of a multiuse property (e.g., sound generated within a commercial unit of a multiuse property building and received within a residential unit of the same building) or multidwelling unit building. In addition, indoor measurements shall be taken if the property line between the receiving property and the source property is a common wall, such as in a multidwelling unit building. The allowable sound level standards for indoors are as shown in Tables I and II.

Editor's Note: See § 204-7, Tables.

D. 

Between 7:00 a.m. and 10:00 p.m., impulsive sound shall not equal or exceed 80 decibels. Between 10:00 p.m. and 7:00 a.m., impulsive sound which occurs less than four times in any hour shall not equal or exceed 80 decibels. Impulsive sound which repeats four or more times in any hour shall be measured as an impulsive sound and shall meet the requirements as shown in Table I.

E. 

Sound from stationary emergency signaling devices shall be regulated in accordance with N.J.A.C. 7:29-1.3, except that the testing of the electromechanical functioning of a stationary emergency signaling device shall not meet or exceed 10 seconds.
