The present invention relates to a method for manufacturing a substantially improved heat-resistant sound absorbing and insulating material. method includes: beating and mixing a fiber material comprising a heat-resistant fiber; forming a web from the beaten and mixed fiber material; stacking the formed web; forming a nonwoven fabric by needle punching as moving a needle up and down through the stacked web; forming a binder-impregnated nonwoven fabric by immersing the nonwoven fabric in a binder solution; and removing a solvent from the binder-impregnated nonwoven fabric. The substantially improved heat-resistant sound absorbing and insulating material manufactured by the method according to the present invention may be installed on a location closest to the noise source of an engine or an exhaust system to reduce radiated noise from the engine or the exhaust system, thereby improving quietness inside a vehicle, and may be applied to a location adjacent to a metal part which is at a temperature of 200° C. or greater to exert heat-insulating function, thereby protecting nearby plastic and rubber parts.
