基于声压幅度比的多声源分离定位决策研究
Research on multi-sound source separation and localization based on the pressure amplitude ratio
摘要
Abstract
The sound pressure amplitude ratio model was applied to the study of multiple sound source localization, and a method for multi-sound source separation and localization based on the sound pressure amplitude ratio was proposed.The method uses the blind signal separation algorithm to separate mixed signals and uses the spectrum estimation similarity method to determine the distribution of each sound source in the mixed signals.Then, according to the amplitude difference factor, the method obtains the distribution of sound source signals of the sensor and uses the sound pressure amplitude ratio model for single sound sources to determine sound source positions to achieve the multi-sound source localization.The blind signal separation algorithm is relatively mature, and the actual sound source signals are mostly non-Gauss, so it satisfies the condition of blind signal separation.The proposed method is practical, and can be widely used to solve the similar problems in signal localization and separation fields.关键词
