    • The present invention relates to a method for improving acoustic noise attenuation, in which the method includes an adaptive control for partial-band echo compensation as well as global-band post-filtering for suppressing residual echo in hand-free devices. This method also uses a level balance as well as controllable frequency-selective echo compensation with partial-band processing. After the frequency-selective echo compensation, the signal is submitted to a post-filtering in another frequency-selective filter using a Wiener-equation adjustment algorithm (Wiener filtering). A single control value (increment vector) is used for controlling both the frequency-selective echo compensation and the other filter. This method can thus be implemented with a very reduced amount of calculations so that it can also be used in simple consumer-directed processors.
    • 本发明涉及一种改善声学噪声衰减的方法,其中该方法包括用于部分带回波补偿的自适应控制以及用于抑制免提装置中残留回波的全频带后置滤波。 该方法还使用等级平衡以及可控频率选择性回波补偿与部分频带处理。 在频率选择回波补偿之后,使用维纳方程调整算法(维纳滤波)将信号提交到另一个频率选择滤波器中进行后置滤波。 单个控制值(增量向量)用于控制频率选择回波补偿和其他滤波器。 因此,该方法可以以非常少的计算量来实现,使得其也可以在简单的面向消费者的处理器中使用。
