摘要： A porous composite material (50) for sound absorption and a method (10) of producing the porous composite material (50) are provided. The method (10) includes preparing (12) a mixture of mechano-electrical conversion elements (56) and electro-thermal conversion elements (58) in an organic solvent. The mixture of the mechano-electrical conversion elements (56) and the electro-thermal conversion elements (58) in the organic solvent is mixed (14) with an aqueous solvent to precipitate a piezoelectric hybrid filler material (54). The piezoelectric hybrid filler material (54) is mixed (16) with a precursor. A foaming operation is performed (18) with the precursor to produce the porous composite material (50).
