    What is ETSI Standard background noise generation system?

  • Listen, Inc. has launched the ETSI standard background noise generation module, a SoundCheck test sequence which calibrates a 4.1 speaker array to conform with the ETSI ES 202 396-1 Standard. This provides an equalized, calibrated playback solution to stress devices in a standardized and repeatable way. The sequence includes a library of real-world binaural recordings from the ETSI standard: cafeteria, pub, crossroad, vehicle, single voice distractor, and office noises. Custom or user-defined binaural recordings can also be used. With a purchase price of just $5,000 for the test sequence, this offers an extremely economical alternative to a conventional $20,000+ stand-alone background noise generation system.

  • SoundCheck test system

  • Furthermore, it offers the advantage that the ETSI standard library is fully integrated with, and managed by, the SoundCheck test system. This means that the calibrated background noise levels can be fully controlled and adjusted as part of a pre-programmed test sequence, significantly reducing test development time as well as simplifying the physical setup.

  • Applications

  • This has many applications, for example evaluating ANC, noise suppression, SNR optimization of microphone arrays, beamforming directionality studies, and more. It is particularly useful for voice recognition testing as the test sequence may include loops to incrementally increase the volume or change the noise and repeat the test until the voice is no longer accurately recognized.
