A moving sound source localization method based on TDOA
The Time Difference of Arrival (TDOA) method has been widely used for sound source localization. However, because of the Doppler-effect, the TDOA method cannot be directly used for locating moving sound sources. This paper develops a moving sound source localization method based on TDOA, combining with Doppler-effect elimination and source plane scanning. This method is suitable for locating so...
متن کاملLocalization of underwater moving sound source based on time delay estimation using hydrophone array
Signal and noise of an underwater moving sound source is used to track the azimuth of a target. Uniform linear array with four hydrophones is used to detect azimuth of target by obtain the time delay information to get azimuth information. Success rate of time delay estimation influenced by characteristics of sound propagation like reflection, reverberation, etc. Experiment in real environment ...
متن کاملActive localization of an intermittent sound source from a moving binaural sensor
An unknown intermittent sound source, at rest or in motion, is considered. We describe an original method to detect its activity and determine its azimuth and range from a moving binaural sensor subject to measurement noise. The proposed source localization scheme is said “active”, as it combines the sensed binaural signals with the sensor motion. It is composed of two stages: first, a pseudoli...
متن کاملRobust localization and tracking of simultaneous moving sound sources using beamforming and particle filtering
Mobile robots in real-life settings would benefit from being able to localize and track sound sources. Such a capability can help localizing a person or an interesting event in the environment, and also provides enhanced processing for other capabilities such as speech recognition. To give this capability to a robot, the challenge is not only to localize simultaneous sound sources, but to track...
متن کاملMonaural Sound Localization
The principles of human sound localization imply binaural (interaural level and time difference) as well as monaural cues. The latter are captured by the head-related transfer functions (HRTFs), which describe the direction-dependent, spectral shaping of the incident sound wave, and can be exploited to determine the direction. In this paper an accurate talker localization strategy in the horizo...
