Description: 采用滤波器组，将盲分离与声源定位结合在一起。滤波器组中分别进行子带处理，并且在每个子带中进行声源定位，最后综合所有子带估计的方向得到多个声源的方位信息，同时将声源信息作为ICA分析的约束条件，可以在色噪声及多得到更好的盲分离效果。其优势在于用滤波器组进行多次的估计声源方向，再加以合适的权值均衡后即可得到更优的估计。-The use of filters will be blind source separation and sound localization together. Filter group were sub-band treatment, and in each sub-band in Sound Source Localization, and finally all the sub-band is estimated to be more than the direction of sound source location information, as well as sound source information as ICA analysis of the binding conditions, colored noise can be better and many of the blind source separation effect. Its advantage lies in a number of filter banks with estimated sound source direction, coupled with an appropriate balance weights can be obtained after the better estimate. Platform: |

Description: 结合马尔可夫过程，提出一种概率论的声源定位算法，并给出了基于DSP的机器人实现。其中声源定位部分采用三个麦克风呈三角形放置，为减小由于噪声等引起的TDOA估计误差，采用马尔可夫过程计算时延，这样计算的时延会更可靠。该方案中的声源定位也属于一维定位，即只需知道声源的方向角-Combination of Markov process, a probability theory of sound source location algorithm, and give the robot based on the DSP implementation. Sound Source Localization in part one of the three microphones were used to place the triangle, in order to reduce the noise caused because of the TDOA estimation error, calculated using Markov process time delay, such delay will be calculated more reliable. The program of the sound source location is also a one-dimensional positioning, that is, only need to know the direction of the sound source angle Platform: |

Description: Interaural time difference is an important cue
for sound localization. In the barn owl (Tyto alba) neuronal
sensitivity to this disparity originates in the brainstem nucleus
laminaris, Afferents from the ipsilateral and contralateral
magnocellular cochlear nuclei enter the nucleus laminaris
through its dorsal and ventral surfaces, respectively, and
interdigitate in the nucleus. Intracellular recordings from these
afferents show orderly changes in conduction delay with depth
in the nucleus. These changes are comparable to the range of
interaural time differences available to the owl. Thus, these
afferent axons act as delay lines and provide anatomical and
physiological bases for a neuronal map of interaural time
differences in the nucleus laminaris. Platform: |
