The invention discloses a high-efficiency sound insulation material which comprises an inner layer and an outer layer, wherein the inner layer is arranged at the top of the outer layer, a sound absorption layer is arranged between the inner layer and the outer layer, vacuum cavities are formed at the top and the bottom of the sound absorption layer, resonance membranes are arranged in the vacuum cavities, and a reinforcing sheet is arranged in the sound absorption layer. The high-efficiency sound insulation material disclosed by the invention is provided with the vacuum cavities, the resonancemembranes and the sound absorption layer; sound can pass through the vacuum cavities at first, and the vacuum cavities can greatly obstruct sound transmission; furthermore, the sound can generate resonance on the resonance membranes made of tinfoil after entering the vacuum cavities, so that sound intensity is weakened; finally, the sound enters the sound absorption layer made of a foam materialand is obstructed; thus, a very good sound absorption effect is achieved, and a sound insulation effect is favorable for being improved.
