The 3M™ Sound Examiner SE-400 Series of sound level meters compute the average sound pressure level (LEQ/LAVG) over the run time, helping you to more accurately assess occupational and environmental noise levels. The Sound Examiner is available in two models: the SE-401, a Class/Type 1 sound level meter that offers remote capability using a removable preamp, and the SE-402, a Class/Type 2 sound level measurement. Enforcement of local noise ordinances requires measuring noise levels and documenting results, particularly when a citation is issued. The easy-to-use SoundPatrol portable digital printing capability requires minimal training, so it can be easily deployed in the field by law enforcement personnel. Both rugged, high-quality devices meet applicable accuracy and performance requirements for sound level meters as defined by ANSI S1.4, ANSI S1.43, IEC 61672, IEC 61010, and IEC 61000-4.
