Frequently Asked Questions

What is the nighttime noise limit near homes in Campbell County?

How does the county measure intermittent noise like a compressor cycling on and off?
Table 2 under § 154.205 applies a correction to the Table 1 limit: plus 5 decibels if the source runs less than 20% of any hour, plus 10 for under 5%, and plus 15 for under 1%, while impulsive noise such as hammering or periodic noise such as a hum gets a 5-decibel reduction instead.
