1 FILTER CASCADES AS ANALOGS OF THE COCHLEA
"... Wave propagation in the cochlea can be modeled at various levels and for vari-ous purposes. We are interested in making models of cochlear signal processing, in analog or digital VLSI or in software, suitable for supporting improved hear-ing aids, speech-recognition systems, and other engineered hea ..."

-cascade approach to modeling the cochlea is based on the obser-vation that small segments of the cochlea act as local filters on waves propa-gating through them. Thus, a cascade of filters can emulate the whole complex distributed hydrodynamic system. This modeling approach can include com-pressive and adaptive
A Decimated Electronic Cochlea on a Reconfigurable Platform
, 2006
"... Any person(s) intending to use a part or the whole of the materials in this thesis in a proposed publication must seek copyright release from the Dean of the Graduate School. Electronic cochlea models are used for physiological modeling as well as in many signal processing tasks such as pitch detect ..."

-end signal processing for different models of the auditory nervous system. This study is concerned with the efficient implementation of cochlea filters in digital hardware. It is demonstrated that computations in the low frequency sections of the cochlea cascade can be reduced by employing decimation. High
A Mammalian Cochlea-based RF Channelizing Filter
"... Abstract-A new type of an RF channelizer-filter ’ has been developed at 20-90 MHz. The lilter topology is derived from an electrical-mechanical analogy of the mammalian cochlea. The channelizer response retains the desirable features of the cochlea including multiple-octave frequency coverage, a lar ..."

A Computational Model of Filtering, Detection, and Compreion in the Cochlea
"... We claim that speech analysis algorithms should be based on computational models of human audition, starting at the ears. While much is known about how hearing works, little of this knowledge has been applied in the speech analysis field. We propose models of the inner ear, or cochlea, which are exp ..."

The main parts of the models concern mechanical filtering effects and the mapping of mechanical vibrations into neural representation. Our model cleanly

A Silicon Cochlea With Active Coupling
"... chip that emulates nonlinear active cochlear signal processing. Modeling the cochlea’s micromechanics, including outer hair cell (OHC) electromotility, this silicon (Si) cochlea features active coupling between neighboring basilar membrane (BM) segments—a first. Neighboring BM segments, each impleme ..."

Improved Silicon Cochlea using Compatible Lateral Bipolar Transistors
- in Advances in Neural Information Processing Systems 8
, 1996
"... Analog electronic cochlear models need exponentially scaled filters. CMOS Compatible Lateral Bipolar Transistors (CLBTs) can create exponentially scaled currents when biased using a resistive line with a voltage difference between both ends of the line. Since these CLBTs are independent of the C ..."
