Sound levels with aural suctioning: Effects of suction size, canal moisture, and distance from the eardrum

open access: yesLaryngoscope Investigative Otolaryngology, 2020
Objective To determine sound levels resulting from aural suctioning of the external auditory canal. Methods Unweighted decibels (dB) and A‐weighted decibels (dBA) sound pressure level measurements were recorded using a retrotympanic microphone in ...

Integration of Soft‐Robotics and Deep Learning to Assess the Coordinated Biosonar Emission and Reception Dynamics in Hipposiderid Bats

open access: yesAdvanced Robotics Research, EarlyView.
Combining a biomimetic soft‐robot with deep‐learning data analytics sheds light on a unique peripheral dynamics seen in the biosonar system of bats: Bats modulate their ultrasonic biosonar signals upon emission as well as reception with variable, yet highly coordinated motion patterns of their noseleaves and pinnae.

Emerging Therapeutic Strategies for Hearing Loss

open access: yesAdvanced Therapeutics, EarlyView.
Challenges still exist in treating hearing loss in cases of severe damage to hair cells or spiral ganglion neurons. Here, a schematic diagram of cochlear sensory hair cells and auditory nerves is presented. It is found that in normal Corti organs, hair cells have upright stereocilia at the top and auditory neurons at the base. Ototoxic drugs, noise, or

Characterization of the ear canal bacterial flora present in hearing Aids (HA) wearing subjects [PDF]

open access: yes, 2019
The use of hearing aids (HA) is considered a predisposing factor for ear microbial infections. We undertook this study to compare the presence and nature of the microbial flora inhabiting of ears of HA and non-HA (nHA) users.

Lycium barbarum Glycopeptide Alleviates Neomycin‐Induced Ototoxicity by Inhibiting Tryptophan Hydroxylase‐Mediated Serotonin Biosynthesis

open access: yesAdvanced Science, EarlyView.
Lycium barbarum glycopeptide (LBGP), which is further extracted from Lycium barbarum polysaccharides, exhibits significant protective effects against neomycin‐induced hearing dysfunction including oxidative stress in cochlea and loss of key cells in cochlea.
