TM
The NoiseGard /digital technology of the S1 DIGITAL uses an innovative
approach. The sound captured by the sensing-microphones is analyzed to calcu-
late the optimum control circuit settings. This calculation is carried out by a high-
performance signal processor using a fully-adaptive algorithm. This fully-adap-
TM
tive algorithm is the core of the NoiseGard /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 spec-
tacles are worn.
