Development of a Basilar Membrane-Inspired Mechanical Spectrum Analyzer Using Metastructures for Enhanced Frequency Selectivity

open access: goldActuators
This study introduces a mechanical spectrum analyzer (MSA) inspired by the tonotopic organization of the basilar membrane (BM), designed to achieve two critical features. First, it replicates the traveling-wave behavior of the BM, characterized by energy

Functional Analyses of Peripheral Auditory System Adaptations for Echolocation in Air vs. Water

open access: yesFrontiers in Ecology and Evolution, 2021
The similarity of acoustic tasks performed by odontocete (toothed whale) and microchiropteran (insectivorous bat) biosonar suggests they may have common ultrasonic signal reception and processing mechanisms.

The evolution of the various structures required for hearing in Latimeria and tetrapods

open access: yesIBRO Neuroscience Reports, 2023
Sarcopterygians evolved around 415 Ma and have developed a unique set of features, including the basilar papilla and the cochlear aqueduct of the inner ear.

Design and Modelling of MEMS Resonators for an Artificial Basilar Membrane

open access: yesEngineering Proceedings, 2023
The human cochlea is undeniably one of the most amazing organs in the body. One of its most intriguing features is its unique capability to convert sound waves into electrical nerve impulses. Humans can generally perceive frequencies between 20 Hz and 20

Localization of the cochlear amplifier in living sensitive ears. [PDF]

open access: yesPLoS ONE, 2011
To detect soft sounds, the mammalian cochlea increases its sensitivity by amplifying incoming sounds up to one thousand times. Although the cochlear amplifier is thought to be a local cellular process at an area basal to the response peak on the spiral ...

Basilar Membrane Tuning [PDF]

open access: yesThe Journal of the Acoustical Society of America, 1973
Georg von Békésy's visual observation of the basilar-membrane travelling wave showed a broad mechanical tuning, quite at variance with the sharp tuning from neural recordings. A few years ago, Johnstone and Boyle applied the Mössbauer technique to the basilar membrane and showed the tuning to be much sharper than previously thought.

Consequences of Location-Dependent Organ of Corti Micro-Mechanics. [PDF]

open access: yesPLoS ONE, 2015
The cochlea performs frequency analysis and amplification of sounds. The graded stiffness of the basilar membrane along the cochlear length underlies the frequency-location relationship of the mammalian cochlea. The somatic motility of outer hair cell is

Longitudinal Coupling in the Basilar Membrane [PDF]

open access: yesJournal of the Association for Research in Otolaryngology, 2001
A systematic and detailed study of the longitudinal coupling exhibited by the basilar membrane (BM) was performed in the excised gerbil cochlea. Contrary to the notion that the adjacent regions of the BM are decoupled from each other, the data indicate that: (a) the BM exhibits longitudinal coupling; (b) the length of the coupled region increases from ...

Correlation and Reliability of Behavioral and Otoacoustic-Emission Estimates of Contralateral Medial Olivocochlear Reflex Strength in Humans

open access: yesFrontiers in Neuroscience, 2021
The roles of the medial olivocochlear reflex (MOCR) in human hearing have been widely investigated but remain controversial. We reason that this may be because the effects of MOCR activation on cochlear mechanical responses can be assessed only ...
