Frequency Band (Cycles per Second) | Maximum Permitted Sound-Pressure Level (Decibels) at the Property Line or Along Any Public Right of Way Within the Property |
|---|---|
20 to 75 | 60 |
75 to 150 | 54 |
150 to 300 | 47 |
300 to 600 | 41 |

1,200 to 2,400 | 34 |
2,400 to 4,800 | 31 |
Above 4,800 | 28 |
If the noise is not smooth and continuous or it is not radiated at night time, one or more of the corrections below shall be added to or subtracted from each of the decibel levels given above. |
Type of Operation or Character of Noise | Corrections in Decibels |
|---|---|
Daytime operation only (8:00 a.m. to 8:00 p.m.) | -/-3 |
Noise occurs less than 5% of any one-hour period | -/-3 |
Noise is of peculiar character (hum, scream, etc.) or is of impulsive character (hammering, pressure release, etc.) (In the case of impulsive noise, the correction shall apply only to the average pressure during an impulse, and impulse peaks shall not exceed the basic standards given above.) | -5 |
Frequency of Ground Motion in Cycles Per Second | Maximum Amplitude of Ground Motion in Inches |
|---|---|
Up to 10 | 0.003 |
11 to 20 | 0.00015 |
21 to 30 | 0.0001 |
31 to 40 | 0.00007 |
41 to 50 | 0.00005 |
