    • According to an embodiment, a method for producing stimulation pulses in a bilateral cochlear implant (CI) is disclosed. The method includes receiving a sound at a first microphone or a first microphone array positioned at or in the vicinity of a first ear of a user of the bilateral CI and receiving the sound at a second microphone or a second microphone array positioned at or in the vicinity of a second ear of the user of the bilateral CI. Furthermore, generating, using the first microphone or first microphone array, a first microphone signal in response to the sound received at the first microphone or first microphone array and generating, using the second microphone or second microphone array, a second microphone signal in response to the sound received at the second microphone or second microphone array. This is followed by filtering the first microphone signal into a plurality of band limited first microphone signals and a filtering the second microphone signals into a plurality of band limited second microphone signals. Later, determining a major sound based on analysis of the first microphone signal and/ or the second microphone signal and/ or at least one of the plurality of band limited first microphone signals and/ or at least one of the plurality of band limited second microphone signals and extracting direction of arrival of the major sound. Based on the determined major source, a primary pulse pattern is generated and a secondary pulse pattern comprising for example a delayed and/ or attenuated copy of the generated primary pulse pattern is then generated. The amount of delay and/ or attenuation is based on the extracted direction of arrival. Finally, stimulating one cochlea using a primary stimulation pulse that is based on the primary pulse pattern and stimulating the other cochlea using a secondary stimulation pulse that is based on the secondary pulse pattern.
    • 根据实施例,公开了一种用于在双侧耳蜗植入物(CI)中产生刺激脉冲的方法。 该方法包括:在位于双边CI的用户的第一耳朵处或附近的第一麦克风或第一麦克风阵列处接收声音,并且在第二麦克风处或第二麦克风阵列处接收声音,所述第二麦克风或位于 双边CI的用户的第二耳朵附近。 此外,响应于在第一麦克风或第一麦克风阵列处接收到的声音,产生使用第一麦克风或第一麦克风阵列的第一麦克风信号,并且响应于第二麦克风信号产生第二麦克风信号 在第二麦克风或第二麦克风阵列处接收的声音。 接下来是将第一麦克风信号滤波成多个频带限制的第一麦克风信号,并将第二麦克风信号滤波成多个带限制的第二麦克风信号。 之后,基于第一麦克风信号和/或第二麦克风信号的分析和/或多个频带限制的第一麦克风信号中的至少一个和/或多个带限制的第二麦克风中的至少一个来确定主要声音 信号和提取主要声音的到达方向。 基于确定的主要源,产生初级脉冲模式,并且然后产生包括例如所产生的初级脉冲模式的延迟和/或衰减副本的辅助脉冲模式。 延迟和/或衰减的量基于所提取的到达方向。 最后,使用基于主脉冲模式的主刺激脉冲刺激一个耳蜗,并且使用基于次脉冲模式的次级刺激脉冲来刺激另一个耳蜗。

    • A signal processor for a hearing device with an implantable stimulator having two or more electrodes for emitting electric charge pulses to neural-fibres of an individual. The processor has a signal path comprising an input circuit adapted to receive an acoustic-signal from the surroundings and provide at least one corresponding input audio-signal; a filter bank adapted to provide atleast one band-limited audio-signal in dependence on the at least one input audio-signal; and a noise filter adapted to attenuate undesired signal components in the at least one band-limited audio-signal and to provide at least one corresponding noise-filtered signal. The processor is characterised in that the portion of the signal path preceding the noise filter neither causes an effective level compression nor an effective level expansion of the atleast one noise-filtered signal when the atleast one noise-filtered signal is derived from an acoustic signal having a level within the comfortable acoustic range.
