         3 . The flooring member of  claim 2  wherein the vertical portion of the first profiled edge is located between the tongue and the upper surface and the vertical portion of the second profiled edge is located between the groove and the upper surface. 
     
     
         4 . The flooring member of  claim 3  wherein the sound-deadening composition is applied to both of the vertical portion of the first profiled edge and the vertical portion of the second profiled edge. 
     
     
         5 . The flooring member of  claim 1  wherein the vertical portion of the first profiled edge is located between the tongue and the upper surface and the vertical portion of the second profiled edge is located between the groove and the upper surface. 
     
     
         6 . The flooring member of  claim 1 , wherein the sound-deadening composition is a solution, a mixture, a suspension, or a combination thereof. 
     
     
         7 . The flooring member of  claim 1 , wherein the sound-deadening composition is solid at room temperature. 
     
     
         8 . The flooring member of  claim 1 , wherein the first wax is present in an amount ranging from about 50 wt. % to about 70 wt. % based on the total weight of the sound-deadening composition. 
     
     
         9 . The flooring member of  claim 1 , wherein the second wax is present in an amount ranging from about 30 wt. % to about 50 wt. % based on the total weight of the sound-deadening composition. 
     
     
         10 . The flooring member of  claim 1 , wherein the first wax has a needle penetration of between about 35 dmm and about 45 dmm at 25° C. 
     
     
         11 . The flooring member of  claim 1 , wherein the second wax has a needle penetration of between about 10 dmm and about 20 dmm at 25° C. 
     
     
         12 . A flooring member comprising:
 a panel body comprising:
 a lower surface; 
 an upper surface opposite the lower surface; 
 a first profiled edge extending between the upper and lower surfaces, the first profiled edge comprising a tongue and at least one vertical portion; 
 a second profiled edge extending between the upper and lower surfaces, the second profiled edge opposite the first profiled edge, the second profiled edge comprising a groove and at least one vertical portion; and 
   a sound-deadening composition applied to the vertical portion of at least one of the first or second profiled edges, the sound-deadening composition comprising:
 a first wax having a melting point between about 82° C. and about 85° C.; and 
 a second wax having a melting point between about 67° C. and about 71° C. 
   
     
     
         13 . The flooring member of  claim 12  wherein the vertical portion of each of the first and second profiled edges is substantially perpendicular to the upper surface. 
     
     
         14 . The flooring member of  claim 13  wherein the vertical portion of the first profiled edge is located between the tongue and the upper surface and the vertical portion of the second profiled edge is located between the groove and the upper surface. 
     
     
         15 . The flooring member of  claim 14  wherein the sound-deadening composition is applied to both of the vertical portion of the first profiled edge and the vertical portion of the second profiled edge. 
     
     
         16 . The flooring member of  claim 12  wherein the vertical portion of the first profiled edge is located between the tongue and the upper surface and the vertical portion of the second profiled edge is located between the groove and the upper surface. 
     
     
         17 . The flooring member of  claim 16 , wherein the first wax is at a concentration, by weight, of about 50 percent and the second wax is at a concentration, by weight, of about 50 percent.
