AH 263

Desktop simulation head with low background noise

AH 263 is a desktop simulation head, which can accurately reproduce the transmission and pickup characteristics of the voice in the middle of the adult head, and can meet the acoustic test requirements of various simulation scenarios, including headphone acoustic test, vehicle smart cockpit, 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-TP.58 to restore the anatomical structure of the human body, AH 263 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.
