Implemented the test methods and requirements for narrowband and broadband in the ACQUA standard TS 26 131-32.
3GPP TS 26 131 and 3GPP TS 26 132 specify the test methods and minimum requirements for evaluating the acoustic characteristics of narrowband (NB), wideband (WB), super-wideband (SWB), and fullband (FB) 2G/3G/4G/5G/WLAN terminals. HEAD acoustics implements the test methods and requirements for narrowband and wideband in the ACQUA standard TS 26 131-32. When combined with other HEAD acoustics components, TS 26 131-32 forms the test platform TP891, TP902, and TP1903, which is certified by GCF/PTCRB (Global Certification Forum/PCS Type Certification Review Board) for mobile device testing.
