1. A laminar spout attachment comprising:

  • (a) a cylindrical housing having an inlet end adapted for coupling to a spout and an outlet end, the housing defining a flow passage connecting the ends;

    (b) a flow-limiting plate mounted in the housing for controlling the volume of liquid flowing through the flow passage, the flow-limiting plate having a plurality of apertures;

    (c) a first screen mounted in the housing downstream from the flow-limiting plate, the first screen permitting liquid flow therethrough while abating noise associated with the liquid flow noise; and

    (d) a velocity-reducing plate located in the housing downstream from the first screen, the velocity-reducing plate having a plurality of orifices therethrough forming a segmented annular ring concentrically aligned with the center of the velocity-reducing plate, wherein the orifices are not axially aligned with the apertures of the flow-limiting plate so that the liquid flowing through the laminar spout attachment must alter direction twice by 90 degrees to pass through the velocity-reducing plate for dispersing the liquid, reducing its associated pressure and abating the liquid'"'"'s flow noise.
