    BIBLIOGRAFIA

    Abstract - (Show below) - (Hide below)

    Describes methods for determining the sound power level or sound energy level of a noise source by comparing measured sound pressure levels emitted by this source (machinery or equipment) mounted in a hard-walled test room, the characteristics of which are specified, with those from a calibrated reference sound source.
