HMEC 25-6A / HMEC 25-KAP-2

L´ensemble casque/micro HMEC 25-6A/-KAP-2 est avant tout conçu pour la communication dans les cockpits d´avion.

￿Comme microphone, on a choisi un microphone autopolarisé haut de gamme. La tension d´alimentation est prise - selon ARINC - sur le circuit de bord.

￿Le casque emploie le système NoiseGard. C´est un système dynamique qui, en plus de reproduire le signal audio, compense électroniquement les bruits

basses fréquences. La compensation active du bruit fonctionne sur le principe selon lequel son et «antison» (déphasé de 180°) s´annulent réciproquement. Pour cette compensation NoiseGard, l´électronique dans le casque nécessite une alimentation séparée qui est integrée dans le cable (voir illustration p. 22).

La communication devient parfaitement intelligible , et il ne faut plus pousser le volume pour couvrir le bruit ambiant.

NoiseGardaugmente le confort, mais

ce n´est pas une protection médicale pour l´ouïe !
