A database of test standard specifications ideal for performance testing of headphones, headsets, and earphones with and without active noise cancellation.
TS 103 640 is a test standard specification database developed for ACQUA based on ETSI TS 103 640. It is ideal for performance testing of headphones, headsets, and earphones with and without active noise cancelers. In addition to basic characteristic evaluations such as audio playback quality, it also includes advanced tests for active and passive noise canceler performance, external audio hear-through clarity, robustness against sound leakage, and more. It also includes internationally standardized voice call quality tests such as 3QUEST, POLQA, and ABLE (LISTENING EFFORT).
