Constant beamwidth beamformer for difference frequency in parametric array
The sound reproduction in air by using a parametric acoustic array [1] has been reported for a few decades. Two inaudible ultrasonic frequencies are produced from the parametric array. Due to the nonlinearity of air, it is possible to produce an audible frequency with its frequency equal to the difference in the two ultrasonic frequencies. However, there is not much work done in controlling the...
متن کاملSound Spatialization Control by Means of Acoustic Source Localization System
This paper presents a system for controlling the sound spatialization of a live performance by means of the acoustic localization of the performer. Our proposal is to allow a performer to directly control the position of a sound played back through a spatialization system, by moving the sound produced by its own musical instrument. The proposed system is able to locate and track the position of...
متن کاملEnergy Based Acoustic Source Localization
A novel source localization approach using acoustic energy measurements from the individual sensors in the sensor field is presented. This new approach is based on the acoustic energy decay model that acoustic energy decays inverse of distance square under the conditions that the sound propagates in the free and homogenous space and the targets are pre-detected to be in a certain region of the ...
متن کاملThree-dimensional Acoustic Source Mapping
When beamforming is applied for acoustic source mapping, the sound pressure contributions of any sound sources are most often mapped to a planar or a surface map. However, some practical applications would benefit from a three-dimensional mapping, where the map consists of a three-dimensional grid. It is shown that the extension of microphone array beamforming techniques to three-dimensional ma...
