Abstract (en)
[origin: WO2004010734A1] A canal hearing device (100) with a dual acoustic seal system for preventing feedback while minimizing occlusion effects. The two-part device comprises a main module (110) and an elongated tubular insert (70) for conducting sound to the tympanic membrane and sealing within the bony region of the ear canal. The main module is positioned in the cartilaginous portion of the ear canal. The tubular insert comprises a sound conduction tube and a cylindrically hollow primary seal (80) medially positioned in the bony region. The device also comprises a secondary seal laterally positioned in the cartilaginous region.
