Listen Offers ETSI Standard Background Noise Generation System

Listen 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. 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.
