Active amplification in auditory systems is a unique and sophisticated mechanism that
expends energy in amplifying the mechanical input to the auditory system, to increase its …

The auditory nervous system is highly nonlinear. Some nonlinear responses arise through
active processes in the cochlea, while others may arise in neural populations of the cochlear …

A dominant theme of acoustic communication is the partitioning of acoustic space into
exclusive, species-specific niches to enable efficient information transfer. In insects, acoustic …

The hair cells in the mammalian cochlea convert sound-induced vibrations into electrical
signals. These cells have inspired a variety of artificial hair cells (AHCs) to serve as …

The mammalian auditory system exhibits rich characteristics that has inspired research for
decades. Some of these key characteristics include frequency selectivity of the basilar …

Hair cells are specialized sensory cells found in the auditory and vestibular systems of many
vertebrates. Many of these cells display an active hair bundle motility that amplifies the hair …

The human auditory mechanism can detect sound frequencies ranging from 20 Hz to 20
kHz, over a broad pressure range of 0–120 dB SPL due to its nonlinear amplification …

Measured auditory nervous spikes often show synchronization, phase-locking, or
entrainment (P. Cariani, Neural Plast. 6 (4), 142–172 (1999) and Kumaresana et al., J …

There is interest in developing devices that mimic the sound transduction of the cochlear
hair cells. Current artificial hair cell (AHC) designs have focused on passive transduction of …

The cochlea is known to exhibit a nonlinear, mechanical amplification which allows the ear
to detect faint sounds, improves frequency discrimination, and broadens the range of sound …
