摘要： A bionic ear cochlear stimulation system has the capability to stimulate fast enough to induce stochastic neural firing, thereby acting to restore “spontaneous” neural activity. Such neurostimulation involves the use of a high rate pulsitile stimulation signal that is amplitude modulated with sound information. Advantageously, by using such neurostimulation, a fitting system may be utilized that does not normally require T-level threshold measurements. T-level threshold measurements are not required in most instances because the high-rate pulsitile stimulation, even though at levels that would normally be a sub-threshold electrical stimulus, is able to modulate neural firing patterns in a perceptible way.

摘要： An In The Ear (ITE) microphone which converts audio sounds into electrical signals which are then processed by a speech processor to generate electrical pulses to stimulate nerves in the cochlea, improves the acoustic response of a Behind The Ear (BTE) Implantable Cochlear Stimulation (ICS) system during telephone use. An acoustic seal provided by holding a telephone earpiece against the ear provides improved coupling of low frequency (up to about 1 KHz) sound waves, sufficient to overcome losses due to the near field acoustic characteristics common to telephones. In an exemplary embodiment, the ITE microphone is connected to a removable ear hook of the BTE ICS system by a short bendable stalk.

摘要： The stimulation provided in the electrically stimulated cochlea is modulated in accordance with the amplitude of a received acoustic signal and the onset of a sound in a received acoustic signal to provide increased sound perception. An onset time that corresponds to the onset of a sound is detected in an acoustic signal associated with a frequency band. A forcing voltage and a transmitting factor are determined, wherein the forcing voltage and the transmitting factor are associated with the frequency band at the detected onset time. The acoustic signal is modulated as a function of the forcing voltage and the transmitting factor to generate an output signal. The generated output signal can be used to stimulate the cochlea. The modulation strategy can be used in conjunction with sound processing strategies that employ frequency modulation, amplitude modulation, or a combination of frequency and amplitude modulation.

摘要： Among other things, enhancing spectral contrast for a cochlear implant listener includes detecting a time domain signal. A first transformation is applied to the detected time domain signal to convert the time domain signal to a frequency domain signal. A second transformation is applied to the frequency domain signal to express the frequency domain signal as a sum of two or more components. A sensitivity of the cochlear implant listener to detect modulation of each component is obtained.
