Most local noise ordinances designate "quiet hours"—for example, from 10 p.m. to 7 a.m. on weekdays and until 8 or 9 a.m. on weekends. So, running a power mower might be permitted at 10 a.m. on Saturday, but not at 7 a.m. Some universally disturbing sounds are commonly banned or restricted.
(8) Yelling, shouting, hooting, whistling, or singing on or near the public street, particularly between the hours of p.m. and a.m., or at any time and place in a manner so as to unreasonably disturb or interfere with the peace, comfort, and repose of owners or possessors of neighboring real property.

NRS 203.010 Breach of peace. Every person who shall maliciously and willfully disturb the peace or quiet of any neighborhood or person or family by loud or unusual noises, or by tumultuous and offensive conduct, threatening, traducing, quarreling, challenging to fight, or fighting, shall be guilty of a misdemeanor.
For residential environments, the accepted decibel level is lower. Any noise exceeding 70 dB is considered disturbing. Residential limits usually start at 60 or 55 dB (the equivalent noise of a regular vacuum cleaner). Time limits usually apply after 10 pm and until 7 am.
Sound is measured in units called decibels. Sounds at or below 70 A-weighted decibels (dBA) are generally safe. Long or repeated exposure to sounds at or above 85 dBA can cause hearing loss.
To be a nuisance, the following factors are considered: Disturbance – the noise must interfere with your enjoyment of living in your home, for example, by preventing you sleeping or reading. Loudness – the louder the noise the more likely it is to be a nuisance.
