7 Μαρ 2023 · In this study, the damping in soft tissues effect on ME sound transmission is investigated, including the Rayleigh and viscoelastic damping, using 3D FE modeling.
7 Φεβ 2024 · The characterization of the vibrations of the middle ear ossicles during sound transmission is a focal point in clinical research.
The mammalian ear is sensitive enough to detect weak sounds [20 μPa, or 0 dB sound pressure level (SPL)] when the vibrations of molecules in the transmitting medium barely exceed displacements due to thermal, Brownian motion (19).
8 Ιουλ 2014 · Sound excites vibration of the eardrum and the three miniscule bones of the middle ear, the last of which acts as a piston to initiate oscillatory pressure changes within the liquid-filled chambers of the cochlea.
9 Αυγ 2014 · The tympanic membrane (TM) or eardrum separates the ear canal from the middle ear cavity and converts the sound pressure waves in the ear canal into mechanical vibrations of the ossicular chain in the middle ear. Sound-induced TM vibration has been measured at the umbo using laser Doppler vibrometry (LDV) (Goode 1994; Whittemore et al. 2004 ...
1 Μαρ 2022 · This study employed a comprehensive set of analysis indices, which included acoustic region SPL and umbo and stapes displacement, to examine the effect of dynamic sound pressure on the ear structure in detail. Furthermore, AACs also affect sound transmission critically.
The human tympanic membrane (TM) transfers sound in the ear canal into the mechanical vibration of the ossicles in the middle ear. The dynamic properties of TM directly affect the middle ear transfer function.
