AH 268

  • Dual axis dynamic acoustic simulation testing system
  • The AH 268 dual axis dynamic acoustic simulation testing system inherits the core functions of the AH 265 high-precision simulated human head model and innovatively integrates a dual axis rotation system and a human-machine interaction control module. It supports controlling the model's horizontal ± 90 ° and vertical ± 90 ° dynamic deflection through a touch interface, or receiving external program instructions to achieve automated testing, breaking through the limitations of traditional static simulation. The system accurately reproduces the human head motion trajectory defined by the ISO 15007-2 standard and can synchronously collect acoustic data in dynamic poses.
