A method and apparatus for noise attenuation. The method includes receiving seismic data associated with at least two vintages (d, d) collected for a same subsurface, wherein the first and second vintages (d, d) are taken at different times; calculating a set of filters (f, fj) that minimizes an energy function (E), wherein the energy function (E) includes a term representing a 4D difference between the first and second vintages (d, d); calculating primaries (p, p) corresponding to the first and second vintages (d, d) based on the set of (f, fj); and calculating a 4D difference (&#x394;) based on the primaries (p, p). The 4D difference (&#x394;) is minimized.
