A one-piece, transparent flexible ear coupler for use with hearing evaluation is disclosed. It includes an annular side wall and a bottom wall forming an acoustic chamber. A flexible adhesive-backed flange is disposed on the periphery of the ear coupler. The flange attaches to the subject's head, firmly holding the ear coupler in place over the ear. The annular side wall has a port for the placement of a transducer assembly, and also has ribs to help lock the transducer assembly in place. The transducer assembly can be placed in an up or down position, and can be switched between positions while the coupler is attached to the subject's head. The ear coupler advantageously conforms to the subject's head, thereby minimizing the likelihood that the ear coupler will become detached during testing. The coupler can be inexpensively manufactured, since its one-piece design allows the use of relatively low-cost processes such as injection molding and thermoforming.
1. An ear coupler assembly comprising:
a body;
a port in said body, said port having a longitudinal axis extending into and out of said port;
an acoustic transducer assembly capable of being releasably attached to said port so that a portion of said assembly extending from said port is generally perpendicular to said longitudinal axis; and
cross-hatched surface protuberances.
2. An ear coupler assembly comprising:
a body;
a port in said body, said port having a longitudinal axis extending into and out of said port;
an acoustic transducer assembly, wherein said acoustic transducer assembly has an arm, and wherein said arm extends laterally away from said port when said acoustic transducer assembly is fitted in said port; and
cross-hatched surface protuberances.
3. The ear coupler according to claim 2 , additionally comprising a port in said body.
4. An ear coupler comprising:
a one-piece body, said body comprising:
an internal chamber,
a port in communication with said chamber for receiving a hearing analysis transducer, and
vibration-reducing surface features
wherein said vibration-reducing surface features comprise cross-hatched protuberances having a waffle type appearance.
5. The ear coupler according to claim 4 wherein said coupler has a center and a target portion, wherein said target portion is in line with said center, and wherein substantially all portions of said body are transparent.
6. The ear coupler according to claim 5 wherein said target portion is in the shape of a target.
