An analog electronic cochlea
  • R. Lyon, C. Mead
  • Computer Science, Physics
  • IEEE Trans. Acoust. Speech Signal Process.
  • 1 July 1988
TLDR
An analog electronic cochlea has been built in CMOS VLSI technology using micropower techniques using a cascade of simple, nearly linear, second-order filter stages with controllable Q parameters suffices to capture the physics of the fluid-dynamic traveling-wave system in the cochleen. Expand

A Low-Power Wide-Dynamic-Range Analog VLSI Cochlea
TLDR
We describe an analog electronic cochlea that processes sounds over 6 orders of magnitude in intensity, with an estimated power dissipation of only a few tens of microwatts. Expand

Improved implementation of the silicon cochlea
TLDR
The original 'Analog electronic cochlea' of R.A. Lyon and C.F. Mead (Trans. Acoust., Speech, Signal Processing, vol.36, no.7, p.1119-34, 1988) used a cascade of second-order filter sections in subthreshold analog VLSI to implement a low-power, real-time model of early auditory processing. Expand

On the importance of time—a temporal representation of sound
TLDR
We show how the nonlinear-ity of the auditory system breaks this equivalence, and is especially important in analyzing complex sounds from multiple sources of different characteristics. Expand

  • 3 April 1990
TLDR
A pitch detector based on Licklider's (1979) duplex theory of pitch perception was implemented and tested on a variety of stimuli from human perceptual tests. Expand

Practical Gammatone-Like Filters for Auditory Processing
TLDR
This paper deals with continuous-time filter transfer functions that resemble tuning curves at particular set of places on the basilar membrane of the biological cochlea and that are suitable for practical VLSI implementations. Expand
