The LHT (Landtop Head Torso) artificial head testing system is applicable to electro-acoustic performance tests of various voice interaction terminals including mobile phones, headsets, smart speakers, in-vehicle voice systems, smart screens and hearing aids under handheld, headset, handheld hands-free and hands-free modes.

The artificial ears of LHTI.1 LN (Landtop Head Torso) artificial head testing system are fitted with high-sensitivity ear simulators, featuring ultra-low background noise down to 16 dB SPL(A) and a maximum sound pressure level up to 149 dB SPL. Its artificial mouth can reproduce full-spectrum sound ranging from 50Hz to 20kHz with extremely low distortion. It serves as the optimal solution for electro-acoustic performance testing of various voice interaction terminals including mobile phones, headsets, smart speakers, in-vehicle voice systems, smart screens and hearing aids under handheld, earphone, handheld hands-free and hands-free working modes.

LHT/N 3.4 is an artificial head equipped with ICP microphones for high-fidelity binaural testing. Taking human body acoustic effects into account, it captures sounds that truly reflect human auditory perception. It connects to data acquisition frontends via BNC interfaces just like standard ICP microphones, requiring no additional power supply and enabling immediate deployment. Its high-quality built-in ICP microphones support calibration with general-purpose microphone calibrators.
