Full Breakdown
10 sets numeric limits on sound from any industrial, commercial or residential operation measured at a residential property line. 5 Hz down to 53 dB at 8,000 Hz. 5 Hz down to 38 dB at 8,000 Hz. Both periods also cap impulsive sound (a single pressure peak or burst under one second) at 80 decibels. 11 sets a parallel standard for sound measured at the property line between commercial or industrial operations: 65 dBA continuous with the same 96-to-53 dB octave-band table and the same 80-decibel impulsive cap, but without a nighttime step-down since it applies between industrial and commercial neighbors rather than residences.
12 exempts eleven categories from both standards, including emergency signaling devices, religious bells and chimes, emergency utility work, motor vehicle race tracks, aircraft noise, public celebrations, public roadways, railroads and the unamplified human voice. C. 15.
