AH 265+AT 235

  • Desktop level simulated human head with torso
  • AH 265 is a desktop level simulated head model with a torso, which can accurately reproduce the transmission and pickup characteristics of the sound of the adult's head in the middle, and can meet the acoustic test requirements of various simulation scenarios, including headphone acoustic test, smart phone, car smart sitting, smart home, laptop, Smartglasses, binaural recording, and other acoustic test applications that need to consider the simulation scenarios of the head architecture.

    By referring to ITU-T P.58 to restore the anatomical structure of the human body, AH 265 also performs high simulation design on the ear canal, which is very suitable for high-precision acoustic measurements of headphones, in ear headphones, and semi in ear headphones, helping to obtain more accurate ANC transfer functions.
