1. An automobile door vent for an automobile inner door panel having a venting aperture formed therein, the door vent comprising:
- a vent formed to be slightly larger than the venting aperture in the automobile inner door panel, the vent having first and second joined layers, one of the first and second layers being made of a flexible thermoset material having memory characteristics, the other of the first and second layers being made of a closed cell non-water absorbent damping material; and
means for fixedly attaching the top edge of one of the layers to the inner door panel such that the door vent covers the venting aperture;
wherein the vent is operable in a hinge-like manner to move from closed position where the vent is closed over the venting aperture, to an open position where the vent allows air passage in only one direction through the venting aperture when the air pressure is increased within the automobile, and wherein the vent is returnable to the closed position to prevent air passage in a second direction.

6. A method for making automobile door vents for an automobile inner door panel having a venting aperture formed therein, the method comprising the steps of:
-
adhering a closed cell, non-water absorbent damping material to a flexible thermoset material having memory characteristics; rolling the resultant material into a thin sheet; applying adhesive to the top edge of one of the damping material and the flexible thermoset material; applying release paper to the adhesive; and then cutting the resulting door vent into a desired shape such that the vent is slightly larger than the venting aperture in the automobile inner door panel.
