Inverse Source Identification based on Acoustic Particle Velocity Measurements
A general applicable acoustic source identification method is the inverse frequency response function technique (IFRF). In the standard IFRF method acoustic pressures measured on a grid in the nearfield of the acoustic source are used. To relate the measured field pressures to the normal velocities on the surface of the source, a transfer matrix is calculated with a boundary element method. The...
متن کاملBlind Source Separation based on the Estimation for the Number of the Blind Sources under a Dynamic Acoustic Environment
Independent component analysis can estimate unknown source signals from their mixtures under the assumption that the source signals are statistically independent. However, in a real environment, the separation performance is often deteriorated because the number of the source signals is different from that of the sensors. In this paper, we propose an estimation method for the number of the sour...
متن کاملResearch of Blind Signals Separation with Genetic Algorithm and Particle Swarm Optimization Based on Mutual Information
Blind source separation technique separates mixed signals blindly without any information on the mixing system. In this paper, we have used two evolutionary algorithms, namely, genetic algorithm and particle swarm optimization for blind source separation. In these techniques a novel fitness function that is based on the mutual information and high order statistics is proposed. In order to evalu...

متن کامل[N382] Acoustic Source Localization based on Pressure and Particle Velocity Measurements
Inverse source identification techniques are used to find the acoustic sources on the surface of a sound radiating object. One of the most general applicable methods is the inverse frequency response function method (IFRF). The standard IFRF technique uses acoustic pressure measurements performed on a measurement grid in the nearfield of an acoustic source to determine the corresponding normal ...
