    • PURPOSE: A device and a method fro removing a musical noise are provided to remove a musical noise by not enabling recognition by a voice as shifting a musical noise component into a noise masking threshold value. CONSTITUTION: A signal converting unit(11) converts an inputted voice signal into a frequency domain area. A noise suppress(12) outputs an enhancement voice signal by restricting a noise of a converted voice signal. A musical noise detection unit(13) detects a musical noise from the enhancement voice signal. A filtering ration calculation unit(14) calculates a power ration of an enhancement voice signal. A masking threshold value calculating unit(15) calculates a masking threshold value. A musical noise deleting unit(16) removes the musical noise.

    • PURPOSE: A device and a method for measuring an arrival angle are provided to use broadband information of a received signal, thereby measuring an arrival angle of high frequency resolution by only two signal receivers. CONSTITUTION: The first and second signal receivers(110,112) are spaced at a fixed distance. The first and second signal receivers receive a broadband signal. The distance is closed to the maximum value. An arrival angle calculation unit(114) performs FFT(Fast Fourier Transform) of the broadband signal of the first and second signal receivers. The arrival angle calculation unit calculates a derived normal frequency and an arrival angle using the distance.

    • PURPOSE: A microphone signal compensation apparatus and a method thereof are provided to compensate the characteristic difference between audio input devices prior to the removal of noises. CONSTITUTION: Constant filtering units(111,113) selectively applies the constant filtering calculation to a signal transferred from plural audio input units, wherein the constant filter calculation is performed based on the average of the ratio of a standard signal to a reference signal among the signals transferred from the plural input units. The constant filter units compensate the characteristic difference among the plural audio input units, and a noise removing unit(116) gets a target signal by removing the noises of the signal compensated by the constant filtering units.
    • 目的:提供麦克风信号补偿装置及其方法,以在消除噪声之前补偿音频输入装置之间的特征差异。 常数滤波单元(111,113)有选择地对从多个音频输入单元传送的信号进行常数滤波计算,其中基于传送的信号中的标准信号与参考信号的比率的平均值执行常数滤波器计算 从多个输入单元。 恒定滤波器单元补偿多个音频输入单元之间的特征差异,噪声去除单元(116)通过去除由常数滤波单元补偿的信号的噪声来获得目标信号。
