The active noise compensation focuses on the monotonous, low-frequency machine noise in the frequency range of 50 – 700 Hz and is thus an ideal supplement to the passive insulation of the cabin.The background noise from attachments such as a vibratory plate or a vibratory hammer can often only be partially reduced because these are too low-frequency (below 50 Hz) and too impulsive. Likewise, high-frequency environmental noise is not reduced (motorway, circular saw, flex, hydrostatic drive) because the size of the quiet zone is too small there.
