New Fundamental Frequency Estimators for Cochlear Implants
Users of cochlear implants experience difficulties in listening to music. Improved processing of music signals for hearing implants requires an accurate and robust estimation of the musical pitch. This paper presents a comparative study of two different signal processing strategies for estimating the fundamental frequencies (F0) of almost-periodic input signals. Their performance with various i...

متن کاملFrequency modulation detection in cochlear implant subjects.
Frequency modulation (FM) detection was investigated in acoustic and electric hearing to characterize cochlear-implant subjects' ability to detect dynamic frequency changes and to assess the relative contributions of temporal and spectral cues to frequency processing. Difference limens were measured for frequency upward sweeps, downward sweeps, and sinusoidal FM as a function of standard freque...
متن کاملThe cochlear geometry as a frequency analyser.
EVIDENCE concerning frequency analysis which was drawn together from several sources allowed the suggestion to be made that the design of the cochlea—i.e. its internal geometry—was itself a frequency analyser to a first approximation (Naftalin, 1965). Two sets of biological observations which seem to be of fundamental importance from the physical (acoustic) point of view may be cited as offerin...
متن کاملMicroengineered hydromechanical cochlear model.
Micromachined fluid-filled variable impedance waveguides intended to mimic the mechanics of the passive mammalian cochlea have been fabricated and experimentally examined. The structures were microfabricated with dimensions similar to those of the biological system. Experimental tests demonstrate acoustically excited traveling fluid-structure waves with phase accumulations between 1.5 and 3 pi ...
