Pick by Voice applications must also function reliably in any harsh and loud warehouse environment. The spoken commands and verifications may to some extent become distorted because of the background noise. Static noises like the constant humming of motors or lamps are filtered out by software. It would be problematic if strong dynamic noises like the bang of a dropping pallet or the clattering of empty bottles seriously hampered optimal speech recognition. 

Playing Out Its Strengths Exactly in this area “NoiseMaster”’s strengths come into play. Equipped with a new intelligent algorithm the headset manages to also filter out explosive dynamic noises. In addition it can differentiate between the noise of the work environment and the commands of the picker. Subsequently a sophisticated mathematical process, adapted from signal processing theory, is used to eliminate dynamic noises such as high-frequency, metallic or human speech and similar background noises above 94 db before the speech signals are forwarded to the recognition module. This guarantees a high speech recognition rate in real time independent of background noise.
