Résumé

Matériau acoustique joue un certain nombre de rôles qui sont importants dans l'ingénierie acoustique tels que le contrôle de l'acoustique des salles, contrôle du bruit industriel et acoustique de studio. Absorbants phoniques sont généralement utilisés pour contrer les effets indésirables de la réflexion du son par les surfaces dures, rigides et de l'intérieur et ainsi contribuer à réduire les niveaux de bruit de réverbération. matériaux à base de ciment peut être utilisé comme finition intérieure pour les surfaces intérieures des bâtiments. Cette revue papier des études d'absorption acoustique de matériaux cimentiers pour leurs avantages potentiels de l'absorption acoustique et d'enquêter sur certains matériaux de finition à base de ciment a ajouté avec des matériaux poreux et fibreux pour améliorer les performances d'absorption acoustique. mortier de ciment projeté contenant des fibres de coton et de perlite d'un montant de perlite dans la région de 80% par rapport aux fibres de coton a donné les meilleurs résultats. Également pulvérisé mortier de ciment fibreux à base de mélange de laine minérale et de liants de ciment atteint haute absorption acoustique.
