Sound transmission by cartilage conduction in ear with fibrotic aural atresia

Chihiro Morimoto, MD, et al.

A clear sound can be heard when a vibration signal is delivered to the aural cartilage from a transducer. This form of transmission is referred to as cartilage conduction (CC). This study showed that CC thresholds were lower than bone conduction thresholds in the low to middle frequency range for patients with fibrotic aural atresia in which fibrotic tissue was connected to the ossicles. Acquired fibrotic aural atresia is not uncommon in the adult population. The results suggest that hearing devices using CC can contribute to rehabilitation of these patients, as well as having other useful audiological applications.
