    Abstract - (Show below) - (Hide below)

    Defines the minimum requirements for 3 basic types of sound level meters, types 0, 1 and 2, along with performance requirements that become progressively less stringent, proceeding from type 0 to type 2. Each type requires three frequency weightings, A, B and C; and two exponential-time-averaging characteristics, fast and slow.
