The invention relates to an irradiation device and a corresponding method for irradiating a radiation absorbing medium, as well as a hearing aid device and a laser surgery device comprising such an irradiation device. A radiation source is configured to generate one or more pulses of electromagnetic radiation and to irradiate the medium with the one or more pulses of electromagnetic radiation. A control unit is configured to control the radiation source such that the time course of the power or intensity of at least one pulse of the one or more pulses of electromagnetic radiation exhibits a rising slope and/or a falling slope, wherein the rising slope and/or falling slope has a maximum gradient which is smaller than a predetermined gradient value, whereby a generation of optoacoustic waves in the medium in response to the rising slope or falling slope, respectively, is avoided or significantly reduced.

Irradiation device and method for irradiating a radiation absorbing medium, hearing aid device and laser surgery device, in particular for laser ear surgery, with such an irradiation device

A cochlear implant for processing signal parameters which are adapted for controlling the cochlear implant, which are based on the audio signal and which enable generating a representation of the audio signal by the cochlear implant includes a receive interface which is implemented to receive the signal parameters and a nerve stimulator for processing the signal parameters to generate nerve cell stimulation signals based on the signal parameters. A device for generating a control signal for a cochlear implant on the basis of an audio signal includes a cochlear parameter extractor for analyzing the audio signal which is implemented to generate signal parameters as input information for the cochlear implant based on an analysis of the audio signal using a human hearing simulation model, and a transmit interface for transmitting the signal parameters to the cochlear implant.
