Internal shearing within the hearing organ evoked by basilar membrane motion.
The vibration of the hearing organ that occurs during sound stimulation is based on mechanical interactions between different cellular structures inside the organ of Corti. The exact nature of these interactions is unclear and subject to debate. In this study, dynamic structural changes were produced by stepwise alterations of scala tympani pressure in an in vitro preparation of the guinea pig ...
متن کاملNear field fluid coupling between internal motion of the organ of Corti and the basilar membrane
The pressure distribution in each of the fluid chambers of the cochlea can be decomposed into a 1D, or plane wave, component and a near field component, which decays rapidly away from the excitation point. The transverse motion of the basilar membrane, BM, for example, generates both a 1D pressure field, which couples into the slow wave, and a local near field pressure, proportional to the BM a...
متن کاملMinimal basilar membrane motion in low-frequency hearing.
Low-frequency hearing is critically important for speech and music perception, but no mechanical measurements have previously been available from inner ears with intact low-frequency parts. These regions of the cochlea may function in ways different from the extensively studied high-frequency regions, where the sensory outer hair cells produce force that greatly increases the sound-evoked vibra...
متن کاملOrgan of Corti potentials and the motion of the basilar membrane.
During sound stimulation, receptor potentials are generated within the sensory hair cells of the cochlea. Prevailing theory states that outer hair cells use the potential-sensitive motor protein prestin to convert receptor potentials into fast alterations of cellular length or stiffness that boost hearing sensitivity almost 1000-fold. However, receptor potentials are attenuated by the filter fo...
متن کاملHearing Aid System Using Basilar Hardware Membrane Model
Our purpose is to apply a basilar hardware membrane model (BMM) to hearing-aid systems to solve some of the problem in existing hearing-aid systems. In this study, we construct a BMM using Simulink. Also, we experiment on the response characteristics of our BMM implementation to C6713DSK, using real sounds and hearing-loss sounds, which imitate a hearing-impaired person’s hearing ability. It is...
