GaVoe noise abatement block

Abstract

A composite noise abatement block ( 12 )( 13 ), containing at least one embedded sound absorbing medium ( 18 ) and at least one orfice ( 19 ) which partially exposes the embedded sound absorbing medium ( 18 ). The composite noise abatement block ( 12 )( 13 ) has connecters ( 14 )( 15 )( 16 ) ( 17 ) allowing multiple blocks to be connected to form an imbricated noise abatement wall (FIG. 9 ). The functional design of the orfice ( 19 ) allows sound to enter the orfice ( 19 ) directly into the sound absorbing medium ( 18 ) where sound quickly dissipates with less resonance than existing noise abatement systems. The noise abatement block walls are used to absorb sound in or on highways, airports, sound studios, theaters and other commercial and non commercial uses.

What is claimed is:  
     
         1 : A noise abatement block, comprising; 
 a. a sound absorbing medium suitable for sound absorption, embedded into a rigid composite shell;    b. said rigid composite shell having at least one orfice;    c. said orfice partially exposing said sound absorbing medium, and;    d. a connecter means to attach multiple noise abatement blocks.    
     
     
         2 : The noise abatement block of  claim 1 , wherein said noise abatement block contains multiple embedded sound absorbing mediums.  
     
     
         3 : The noise abatement block of  claim 1 , wherein said noise abatement block contains multiple orfices, which partially expose multiple sound absorbing mediums.  
     
     
         4 : A molding means for constructing a noise abatement block comprising; a rigid mold suitable for molding one or more noise abatement blocks with one or more orfices, wherein; 
 a. one or more sound absorbing mediums are suspended by suspension means, in said rigid mold, and;    b. a fluid bonding material, suitable for pouring is poured into the rigid mold and let cure.    
     
     
         5 : The molding means for contructing a noise abatement block of  claim 4 , wherein said cured noise abatement block is removed from said mold.  
     
     
         6 : The molding means for constructing a noise abatement block of  claim 4 , wherein a metal or fiber reinforcement means is incorporated into said noise abatement block matrix, prior to pouring said fluid bonding material.
