The invention relates to a noise absorber and a pneumatic tire comprising the noise absorber. The noise absorber comprises one or more internal sound absorbing material layers (3), one or more external sound absorbing material layers (1) and an interface noise reduction adhesion layer (2) arranged between the internal sound absorbing material layers (3) and the external sound absorbing material layers (1); and an external adhesion layer (5) which is arranged on the external sound absorption material layers (1) and is opposite to the interface noise reduction adhesion layer (2), wherein a middle filling structure (4) is arranged in the middle of the external sound absorbing material layers (1), one side of the middle filling structure (4) is in direct contact with the internal sound absorbing material layers (3), and the other side of the middle filling structure (4) is open. The noise absorber has a good adhesion effect and good noise reduction and vibration reduction effects.
