Analog VLSI model of binaural hearing - Neural Networks, IEEE Transactions on
The stereausis model of biological auditory processing was proposed as a representation that encodes both binaural and spectral information in a unified framework. We describe a working analog VLSI chip that implements this model of early auditory processing in the brain. The chip is a 100 000-transistor integrated circuit that computes the stereausis representation in real time, using continuo...
متن کاملAnalog VLSI Hearing Systems
Animals hear through complex mechanical–neural signal processing systems. We would like to be able to duplicate this functionality in machines, for purposes of recognizing speech and for other sound-related tasks. Computational models on digital computers offer one method for exploring models of auditory processing, but in this paper we discuss the use of analog VLSI systems as a promising alte...
متن کاملAn Analog VLSI Model of Periodicity Extraction
This paper presents an electronic system that extracts the periodicity of a sound. It uses three analogue VLSI building blocks: a silicon cochlea, two inner-hair-cell circuits and two spiking neuron chips. The silicon cochlea consists of a cascade of filters. Because of the delay between two outputs from the silicon cochlea, spike trains created at these outputs are synchronous only for a narro...
متن کاملImportance of binaural hearing.
An essential task for the central auditory pathways is to parse the auditory messages sent by the two cochleae into auditory objects, the segregation and localisation of which constitute an important means of separating target signals from noise and competing sources. When hearing losses are too asymmetric, the patients face a situation in which the monaural exploitation of sound messages signi...
متن کاملA Bidirectional Analog VLSI Cochlear Model
A novel circuit is presented for implementing a bidirectional passive cochlear model in analog VLSI. The circuit includes a subcircuit for modelling the fluid in the cochlear duct, and a subcircuit for modelling the passive basilar membrane. The circuit is compared to the classical 1-D transmission line cochlear model and found to be equivalent. The approach leads to an unexpected fault toleran...
