To conduct quantitative testing of key indicators including time delay, frequency response, loudness, idle channel noise, echo cancellation, switching characteristics, double-talk performance and background noise transmission with high precision, Landtop Technology has launched the AaSQ electroacoustic test system with fully independent intellectual property rights.

Specially designed for the evaluation of call voice quality and acoustic effects, this system adopts a highly integrated architecture. It realizes closed-loop full-process testing including automatic data acquisition, in-depth analysis, signal playback and automatic test report generation, delivering one-stop technical support for the R&D design and verification testing of eCall systems.
