Noise can be damaging to health. Sound level meters can reliably establish the load to which noise sources, such as machines, roads or factories, expose people and the environment. Safety precautions can then be put in place immediately or existing soundproofing can be repaired or strengthened. These handy, battery-operated devices are particularly mobile and you can use them anywhere that you need to observe noise limits. This applies in offices and schools, as well as industrial factories.
