Noise occurs between the hours of 10:00 p.m. and 7:00 a.m. | - 3 |
Noise occurs less than 5% of any one-hour period. | + 5 |
Noise if of periodic character (hum, scream, etc.) or impulsive character (hammering, 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 |
