Tapered vent for a hearing instrument

摘要

A vent having a reduced cross-section or taper permits the fabrication of very small hearing instruments while providing the necessary openings for the receiver tube and the vent in the tip of the instrument. The reduced cross-section provides sufficient clearance for the full cross-section of the receiver tube, without sacrificing the performance of the vent. The modified vent may be created in a CAD environment using Boolean modeling operations.
