    • An exemplary method of reducing an effect of ambient noise within an auditory prosthesis system includes dividing an audio signal presented to an auditory prosthesis patient into a plurality of analysis channels each containing a frequency domain signal representative of a distinct frequency portion of the audio signal, determining a signal-to-noise ratio and a noise reduction gain parameter based on the signal-to-noise ratio for each of the frequency domain signals, applying noise reduction to the frequency domain signals in accordance with the determined noise reduction gain parameters to generate a noise reduced frequency domain signal corresponding to each of the analysis channels, and generating one or more stimulation parameters based on the noise reduced frequency domain signals and in accordance with at least one of a current steering stimulation strategy and an N-of-M stimulation strategy. Corresponding methods and systems are also disclosed.
    • 降低听觉假体系统中的环境噪声的影响的示例性方法包括将呈现给听觉假体患者的音频信号划分成多个分析通道,每个分析通道包含表示音频信号的不同频率部分的频域信号,确定 基于每个频域信号的信噪比的信噪比和噪声降低增益参数,根据所确定的噪声降低增益参数将噪声降低应用于频域信号,以产生 对应于每个分析通道的噪声降低的频域信号,以及基于噪声降低的频域信号并根据当前的转向刺激策略和N-M刺激策略中的至少一个产生一个或多个刺激参数 。 还公开了相应的方法和系统。
