28 8  The Noise Logging Principal  An understanding on how the Zonescan Loggers build the Histogram will help when interpreting the results. The following section explains how the sampling process works. The tables depict when the logger takes a noise sample and what the sample is caused by, e.g a passing car or leak. Traffic & Consumption noise should be ignored. A large number of samples at the quietest level, indicate a consistant sound that could be a leak which never stops. The Leak is the closest to the loudest, quietest noise.
