  • Noise Pollution
  • Exhaust Systems (Mechanical Components)
DEF

A muffler that attenuates by reflecting sound back to the source.

Domaine(s)
  • Acoustique (Physique)
  • Pollution par le bruit
  • Système d'échappement (Composants mécaniques)
DEF

Silencieux constitué de filtres acoustiques et fonctionnant par désadaptation d'impédance acoustique.

CONT

Étant donné que l'atténuation du silencieux réactif est sélective en fréquences, il y a un intérêt certain à dimensionner la ligne d'échappement de sorte que les harmoniques moteur coïncident avec des fréquences de fortes impédances d'entrée de l'échappement.
