The NoiseGardTM/digital technology of the S1 DIGITAL uses an innovative approach. The sound captured by the sensing-microphones is analyzed to calculate the optimum control circuit settings. This calculation is carried out by a high- performance signal processor using a fully-adaptive algorithm. This fully-adaptive algorithm is the core of the NoiseGardTM/digital technology and ensures that the currently dominant sound components are particularly well attenuated. The attenuation curve resulting from the adaptation is therefore always optimised for the current situation.

The dominat sounds components at the ear depend not only on the noise of the aircraft but also on the user’s position in the cockpit and, above all, on how the sound is transmitted through the headphones to the ear. This, in turn, depends on the fit of the headphones, head and ear anatomy and on whether or not spectacles are worn.
