3-dimensional Playback of Acoustic Sound Scenarios
3PASS lab / 3PASS flex are playback and recording systems capable of preserving and reproducing real-life background noise scenarios in different test rooms or in vehicle cabins.
3PASS lab is especially suited for the evaluation of complex noise reduction algorithms, e.g. as often found in modern smartphones. 3PASS lab conforms to the ETSI standard TS 103 224 and includes a noise database as specified by the standard.
3PASS flex is particularly suited for multi point noise simulation (MPNS), e.g. as required for testing multi-microphone car hands-free systems. 3PASS flex conforms with the new Annex F of the ITU-T standards P.1100/P.1110.
3PASS lab / 3PASS flex is a Windows® software which is used in conjunction with the front end labBGN as well as other HEAD acoustics components.
