       15 . A method of producing a porous, plate-shaped metallic composite, including the steps of: 
 providing metallic fibers, and compressing and fusing said metallic fibers together in a single step.    
   
   
       16 . A method according to  claim 15 , wherein said providing step comprises providing metallic fibers in the form of prefabricated metallic fiber mats.  
   
   
       17 . A method according to  claim 15 , wherein said metallic fibers are derived from bulk material and are initially separated.  
   
   
       18 . A method according to  claim 15 , wherein opposite flat sides of said metallic composite are fused to respective cover layers in the form of wire meshes.  
   
   
       19 . A method according to  claim 15 , that is carried out continuously to form an endless metallic composite.  
   
   
       20 . A method according to  claim 15 , wherein said method is carried out in inert gas.  
   
   
       21 . A method according to  claim 15 , wherein said metallic fibers are fused together via pulse fusing.  
   
   
       22 . A method according to  claim 21 , wherein said pulse fusing is capacitor pulse fusing.  
   
   
       23 . A method according to  claim 15 , wherein the fusing step is carried out in less than 1 s.  
   
   
       24 . A method according to  claim 23 , wherein the fusing step is carried out in less than 10 ms.  
   
   
       25 . A method according to  claim 15 , wherein said metallic fibers are subjected to pressure prior to or during the fusing step.  
   
   
       26 . A method according to  claim 25 , wherein the pressure is produced with a pressing force of 0.1 N/mm 2  to 10 N/mm 2 .  
   
   
       27 . A method according to  claim 26 , wherein said pressing force is from 1.5 N/mm 2  to 6.0 N/mm 2 .  
   
   
       28 . A sound-dampening panel formed of metallic fiber fleece having metallic fibers that are fused together, wherein said fused-together fibers are disposed between two cover layers.  
   
   
       29 . A sound-dampening panel according to  claim 28 , wherein said metallic fiber fleece is fused to said cover layers.  
   
   
       30 . A sound-dampening panel according to  claim 28 , wherein said cover layers are in the form of wire meshes.  
   
   
       31 . A gas burner insert formed of a metallic fiber fleece having metallic fibers that are fused together, wherein said fused-together metallic fibers are disposed between two cover layers.  
   
   
       32 . A gas burner insert according to  claim 31 , wherein said cover layers are in the form of wire meshes.
