Sound Source Localization Using a 2D Acoustic Vector Sensor
In this research, a two dimensional acoustic vector sensor is used to determine the direction of arrival (DOA) of a sound source relative to the sensor. Existing solutions have focussed on using two acoustic vector sensors (AVS) or an array of AVS and not on using one AVS. This paper focusses on the accuracy of a sound source localization algorithm and the influence of ambient noise and reflect...
متن کاملWideband source localization using a distributed acoustic vector-sensor array
We derive fast wideband algorithms, based on measurements of the acoustic intensity, for determining the bearings of a target using an acoustic vector sensor (AVS) situated in free space or on a reflecting boundary. We also obtain a lower bound on the mean-square angular error (MSAE) of such estimates. We then develop general closed-form weighted least-squares (WLS) and reweighted least-squares...
متن کاملA Decoupled Approach for Near-Field Source Localization Using a Single Acoustic Vector Sensor
This paper considers the problem of three-dimensional (3-D, azimuth, elevation and range) localization of a single source in the near-field using a single acoustic vector sensor (AVS). The existing multiple signal classification (MUSIC) or maximum likelihood estimation (MLE) methods which require a 3-D search over the location parameter space are computationally very expensive. A computationall...
متن کاملImprove range-free localization accuracy in wireless sensor network using DV-hop and zoning
In recent years, wireless sensor networks have drawn great attention. This type of network is composed of a large number of sensor nodes which are able to sense, process and communicate. Besides, they are used in various fields such as emergency relief in disasters, monitoring the environment, military affairs and etc. Sensor nodes collect environmental data by using their sensors and send them...
متن کاملLow latency localization of multiple sound sources in reverberant environments.
Sound source localization algorithms determine the physical position of a sound source in respect to a listener. For practical applications, a localization algorithm design has to take into account real world conditions like multiple active sources, reverberation, and noise. The application can impose additional constraints on the algorithm, e.g., a requirement for low latency. This work define...
