Disclosed is a method for manufacturing a soundproofing board part having improved sound absorption performance. The soundproofing board part is manufactured by using, as a material, a recycled soundproofing material which contains a polyurethane foam having excellent sound absorption performance and impact resilience during the press molding; and by producing a sound absorption part on the back surface of the soundproofing board part through a remolding processing method. Also disclosed is a soundproofing board part manufactured by the method. Accordingly, sound absorption performance of the soundproofing board part is improved by about 20% or greater, manufacturing cost thereof may be reduced by recycled resources utilizing waste sheets, and manufacturing process may be simplified compared the related art.
