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.
