True integrating environmental noise monitor and sound exposure level meter. Volume 1: Users guide

This report summarizes desirable features and factors in environmental noise monitors, in general, and in particular, monitors which measure the impulsive noise created by military sources. Particular emphasis is placed on the need to have a true-integrating detector to properly measure these impulsive sources. Based on these needs, a noise monitor has been designed and constructed. This report summarizes the operations and components of this monitoring unit. Volume 2 describes the construction, parts lists, layouts, and schematics of the monitoring unit.
