    摘要： A hearing protection process comprises (a) providing at least one hearing protection device comprising at least one sound barrier comprising at least one substantially periodic array of structures disposed in a first medium having a first density, the structures being made of a second medium having a second density different from the first density, wherein one of the first and second media is a viscoelastic medium having a speed of propagation of longitudinal sound wave and a speed of propagation of transverse sound wave, the speed of propagation of longitudinal sound wave being at least about 30 times the speed of propagation of transverse sound wave, and wherein the other of the first and second media is a viscoelastic or elastic medium; and (b) interposing the hearing protection device between an acoustic source and an acoustic receiver in the form of a human ear.

    摘要： A vessel having a bottom with a vertical center-line and an annular side wall extending upward from the bottom of the vessel terminating into a rim portion. The vessel is further provided with at least one pouring spout formed in the side wall and extends peripherally about the side wall for at least a 75 degree arc with respect to the vertical centerline of the bottom. The pouring spout consists of two opposing concave upper pouring spout surfaces which converge upon and join a concave lower throat surface. The pouring spout thus provides a cross-sectional flow pattern initially in the shape of a convex-sided V that reforms into a round non-turbulent stream regardless of the flow rate of the liquid being poured. A complementary closure having at least one array of openings, for venting steam and/or straining liquids being prepared in the vessel is also disclosed.
