摘要： A system includes a plurality of inputs each configured to receive a filtered version of a source signal. The system extracts the energy information from each input signal and compares the energy information of a plurality of input signals. Alternatively, the system extracts energy information from a signal that is the difference of two input signals. Based on the energy information, the system determines at least one parameter that may be changed in at least one circuit in a plurality of circuits to minimize the differences in energy of the input signals or to minimize the energy of the difference signal. Parameters may include for example amplification, delay, and corner frequency values.The set of circuits may include microphone interface circuits. Merely by way of example, a system with microphone interface circuits may be included in a hearing enhancement device or in a hands-free earpiece.
摘要翻译：系统包括多个输入，每个输入被配置为接收源信号的滤波版本。该系统从每个输入信号中提取能量信息，并比较多个输入信号的能量信息。或者，系统从作为两个输入信号的差的信号提取能量信息。基于能量信息，系统确定可以在多个电路中的至少一个电路中改变的至少一个参数，以最小化输入信号的能量差异或最小化差分信号的能量。参数可以包括例如放大，延迟和转角频率值。该组电路可以包括麦克风接口电路。仅举例来说，具有麦克风接口电路的系统可以包括在听力增强装置中或免提耳机中。
