Abstract

A transducer is configured to couple to the cochlear fluid so as to transmit sound with low amounts of energy, such that feed back to a microphone positioned in the ear canal is inhibited substantially. The cochlear fluid coupled hearing device can allow a user to determine from which side a sound originates with vibration of the cochlea and the user can also receive sound localization cues from the device, as feedback can be substantially inhibited. The transducer may be coupled to the cochlear fluid with a thin membrane disposed between the transducer and the cochlear fluid, for example with a fenestration in the cochlea. In some embodiments, a support coupled to the transducer directly contacts the fluid of the cochlea so as to couple the transducer to the cochlear fluid.
