Abstract

L'invention concerne un méta-matériau acoustiques (100,100'), ainsi qu'un procédé pour sa fabrication. Le méta-matériau acoustique comprend une pluralité de canaux (101) ou colonnes (101') ayant chacun une même section transversale avec un rayon hydraulique entre 5 et 300 µm, disposés avec un espacement périodique (t,s) entre 2 et 600 µm. On peut ainsi obtenir un réseau hautement dense pouvant offrir une absorption et/ou impédance acoustiques optimales sur une large bande de fréquences. Son procédé de fabrication comprend une fabrication additive avec plusieurs étapes consécutives de dépôt de matériau pour former, dans chaque étape, une couche (203) comportant une pluralité de cellules (204) périodiquement répétées, séparées par des parois (104). Les couches (203) déposées dans les étapes consécutives de dépôt de matériau sont empilées avec leurs cellules (204) respectives alignées de manière à former des canaux (101, 206').
