Automotive Cav Suab Simulator: Cov Dagital Lub Plawv Rau Cov Tsheb Niaj Hnub
Lub cav suab simulator (ESS) yog lub tshuab hluav taws xob uassynthesizes cov cuab yeej siv lub cav acoustics, feem ntau rau EVS, hybrids, lossis me-cov tshebacoustic engineering fused nrog kev tsav tsheb psychology-Far dhau lub suab tawm tshiab ua si .
