Aspects of the subject technology provide for auto-adaptive noise cancellation, which may be provided with a substantially flat frequency response. In one or more implementations, a noise cancellation signal is combined with a pass-through audio signal at a ratio based on mixing curve control. The blending curve may be one of a plurality of blending curves defined for a plurality of respective operating states of the electronic device. 本主题技术的各方面提供了自动自适应噪声消除，其可被提供有基本上平坦的频率响应。在一个或多个具体实施中，以基于混合曲线控制的比率将噪声消除信号与直通音频信号组合。该混合曲线可以是针对电子设备的多个相应操作状态定义的多个混合曲线中的一者。
