Title: Innovations of Peter M Seligman
Introduction
Peter M Seligman is a notable inventor based in Essendon, Australia. He has made significant contributions to the field of cochlear prosthetics, holding a total of 5 patents. His work focuses on improving auditory technology, particularly for individuals with hearing impairments.
Latest Patents
One of his latest patents is the Multi-peak speech processor. This innovative system employs a multi-spectral peak coding strategy to extract several spectral peaks from incoming acoustic signals received by a microphone. The system encodes this information into sequential pulses that are sent to selected electrodes of a cochlear implant. The first formant (F1) spectral peak, ranging from 280-1000 Hz, and the second formant (F2) spectral peak, ranging from 800-4000 Hz, are encoded and presented to apical and basal electrodes, respectively. This selection follows the tonotopic organization of the cochlea, ensuring that high-frequency spectral information is sent to more basal electrodes while low-frequency spectral information is directed to more apical electrodes. Additionally, spectral energy in the regions of 2000-2800 Hz, 2800-4000 Hz, and above 4000 Hz is encoded and presented to three fixed electrodes. The fundamental or voicing frequency (F0) determines the pulse rate of stimulation during voiced periods, while a pseudo-random aperiodic rate governs the pulse rate during unvoiced periods. The amplitude of the acoustic signal in the five bands determines the stimulus intensity.
