IEC 63296-3:2025

IEC 63296-3:2025 specifies the method for measuring the battery duration at a defined sound pressure level for continuous music playback of battery-operated wearable powered loudspeaker equipment. A primary battery or secondary battery can be used as a power source for such a shoulder-carried or body-worn loudspeaker and its composite device. In addition, only equipment that can be placed on or hung from a head and torso simulator (HATS) is covered. Bone conduction speakers are excluded. Portable loudspeaker equipment also supporting video playback as the main function is not covered by this document.
