This standard specifies minimum requirements for three basic types of sound level meters, types 0, 1, and 2, with performance requirements that become progressively less stringent, proceeding from type 0 to type 2. For each type, the standard requires three frequency weightings, A, B, and C; and two exponential-time-averaging characteristics, slow and fast.
