发明名称 Directional hearing enhancement
摘要 A device for improving the hearing acuity of a user directionally, including a pair of reflectors to be supported behind the user's ears so as to increase the effective area of the outer ear and reflect an increased amount of sound energy into the user's ears from a position in front of the user. The reflectors are supported alternatively on a headband or a cap equipped with horizontally extending straps which permit adjustment of the location of each reflector, and the reflectors are attached to the headband or straps by a respective base plate to which each reflector is attached pivotably so that the reflectors can be adjusted to optimum positions.
