Real-Time Multirate Multiband Amplification for Hearing Aids

IEEE Access, 2022
Hearing loss is a common problem affecting the quality of life for thousands of people. However, many individuals with hearing loss are dissatisfied with the quality of modern hearing aids.

Auditory System

Definitions, 2020
The outer ear funnels sound vibrations to the eardrum. The folds of cartilage surrounding the ear canal are called the pinna. Sound waves are reflected and attenuated when they hit the pinna, and these changes provide additional information that helps ...

Functional changes in the auditory cortex and associated regions caused by different acoustic stimuli in patients with presbycusis and tinnitus

Frontiers in Neuroscience, 2022
Presbycusis and tinnitus are the two most common hearing related pathologies. Although both of these conditions presumably originate in the inner ear, there are several reports concerning their central components.

Purinergic Signaling Controls Spontaneous Activity in the Auditory System throughout Early Development

Journal of Neuroscience, 2020
Spontaneous bursts of electrical activity in the developing auditory system arise within the cochlea before hearing onset and propagate through future sound-processing circuits of the brain to promote maturation of auditory neurons.

Age-Related Deficits in Electrophysiological and Behavioral Measures of Binaural Temporal Processing

Frontiers in Neuroscience, 2020
Binaural processing, particularly the processing of interaural phase differences, is important for sound localization and speech understanding in background noise. Age has been shown to impact the neural encoding and perception of these binaural temporal

Dopamine in Auditory Nuclei and Lemniscal Projections is Poised to Influence Acoustic Integration in the Inferior Colliculus

Frontiers in Neural Circuits, 2021
Dopamine (DA) modulates the activity of nuclei within the ascending and descending auditory pathway. Previous studies have identified neurons and fibers in the inferior colliculus (IC) which are positively labeled for tyrosine hydroxylase (TH), a key ...

The Cl--channel TMEM16A is involved in the generation of cochlear Ca2+ waves and promotes the refinement of auditory brainstem networks in mice

eLife, 2022
Before hearing onset (postnatal day 12 in mice), inner hair cells (IHCs) spontaneously fire action potentials, thereby driving pre-sensory activity in the ascending auditory pathway.

Cochlear Inflammaging in Relation to Ion Channels and Mitochondrial Functions

Cells, 2021
The slow accumulation of inflammatory biomarker levels in the body—also known as inflammaging—has been linked to a myriad of age-related diseases. Some of these include neurodegenerative conditions such as Parkinson’s disease, obesity, type II diabetes ...

Discovery of a lipid synthesising organ in the auditory system of an insect [PDF]

, 2012
Weta possess typical Ensifera ears. Each ear comprises three functional parts: two equally sized tympanal membranes, an underlying system of modified tracheal chambers, and the auditory sensory organ, the crista acustica.

Early Deletion of Neurod1 Alters Neuronal Lineage Potential and Diminishes Neurogenesis in the Inner Ear

Frontiers in Cell and Developmental Biology, 2022
Neuronal development in the inner ear is initiated by expression of the proneural basic Helix-Loop-Helix (bHLH) transcription factor Neurogenin1 that specifies neuronal precursors in the otocyst.
