The invention discloses a radial multidirectional dispersed sound-absorbing material, and belongs to the field of sound absorbing materials; according to the radial multidirectional dispersed sound-absorbing material, on one hand, sound waves are converted into the vibration force of slow vibration rods; under the vibration effect of the slow vibration rods, the slow vibration rods are in a radialshape, so the sound is transmitted into the sound-absorbing material along the continuously changing direction of the slow vibration rods, and through similarly breaking up the entirety into parts, the sound can be differentiated; further, the sound absorption and noise reduction effects of the sound-absorbing material are obviously improved. On the other hand, when the sound is transmitted to the slow vibration rods; sound propagation speed is reduced, the time of sound in the sound-absorbing material is prolonged, and furthermore, the effect of sound consumption is achieved, so that sound absorption effect is better; and meanwhile, the upward vibration amplitude of the slow vibration rods can be effectively increased by matching with the effect of a differentiation-assisting fixed ball,so that the differentiation range of the sound-absorbing material to the sound is larger, and the sound absorption effect of the sound-absorbing material is further improved.
