A cochlear implant is a way to revive hearing in the poorer ear. BAHAs vs. Traditional Hearing Aids . For some people with conductive or mixed hearing loss, both a hearing aid and a BAHA can ...
Structural diagram of the cochlea showing how fluid pushed in at the oval window moves, deflects the cochlear partition, and bulges back out at the round window. The cochlea ( pl. : cochleae) is a spiraled, hollow, conical chamber of bone, in which waves propagate from the base (near the middle ear and the oval window ) to the apex (the top or ...
The parallel processing of these signals, however, is performed separately and optimized for both acoustic hearing (focusing on low-frequency hearing) and cochlear implant stimulation (focusing on high-frequency hearing). The hearing aid is integrated in the ear hook and the amplified signals are forwarded to the auditory pathway via an ear mould.
If hearing loss exists in the better ear then a system in the good ear that combines the function of a regular hearing aid with that of a CROS aid is recommended. This configuration is called a BiCROS system. Current CROS devices utilize wireless streaming to transmit the signal from the poor ear to the better hearing ear.
The diagram below illustrates the complex layout of the compartments and their divisions: [4] Cross-section through the cochlea, showing the different compartments (as described above) The basilar membrane widens as it progresses from base to apex. Therefore, the base (the thinnest part) has a greater stiffness than the apex. [4]
The trapezoid body is where most of the cochlear nucleus (CN) fibers decussate (cross left to right and vice versa); this cross aids in sound localization. [16] The CN breaks into ventral (VCN) and dorsal (DCN) regions. The VCN has three nuclei. [clarification needed] Bushy cells transmit timing info, their shape averages timing jitters ...
