Portable multimedia equipment - Determination of battery duration - Part 1: Powered loudspeaker equipment
Abstract
This standard specifies methods of measurement for battery duration on powered loudspeaker equipment. The operating time of a battery-powered powered loudspeaker varies greatly depending on the reproduced sound pressure from the loudspeaker. Since the reproduced sound pressure of a powered loudspeaker varies depending on the purpose of use, it is a measurement method that measures the battery operating time at different sound pressures.
