1.1 Overview
The SoundAdvisor Model NMS044 noise monitoring system (NMS044,
system) is the practical solution to long-term or short-term,
unattended sound level monitoring. Power is supplied by a 12 V
battery, and the system is charged by a solar panel, chosen specifically
for the area sunlight availability. It is lightweight, as little as 50 lbs, so
one person can carry to a site and setup within a few minutes.
