In this paper an adaptive single input - multiple output feed-forward system for sound radiation from a vibrating plate is investigated. Finite impulse response filters are used to generate control signals for each actuator based on the common input signa... see more

In the article was solved the problem of radiation of a sound by the electroacoustic transducer which is executed in the form of a thin spherical cover, using a pass-through method. The outer and inner surfaces of the shell are completely electroded.The a... see more

The paper deals with methods and algorithms for increasing the accuracy of unmanned aerial vehicle identification. Accumulation of data on radiation parameters during the session of observation of an object allows to make continuous specification of the m... see more

The use of double-sheet enclosures with an intermediate air chamber in façades guarantees a higher quality of acoustic insulation against external airborne noise. The effective advantages of the intermediate air chamber depend mainly on its airtightness a... see more

Active Noise Control (ANC) systems are usually designed in the feed-forward structure with adaptive linear control filters. However, performance of such systems, when a vibrating plate is used as the secondary source, may be poor due to significant non-li... see more

The paper is an analytical and experimental study of smart structure, which consist of steel plate with bonded PZTs and porous elastomer layer. Active control of sound radiation from a clamped at the edge square plate is examined. Simulations and numerica... see more

This study focuses on the sound radiation of a vibrating flat annular plate. The rigorous theoretical considerations deal with sometime-harmonic and axisymmetric vibrations. Three different boundary configurations are considered, i.e. one of the plate’s e... see more

This work is focused on effect of inplane loading on sound generated by an airplane taking off from a floating runway. Assuming runway as a simple, infinitely long beam, modeled as a Timoshenko-Mindlin plate floating on water, an expression for sound radi... see more

This paper deals with the effect of secondary actuator positioning in an active structural acoustics control (ASAC) experiment. The ASAC approach is based on minimizing the sound radiation from structures to the far field by controlling the structural vib... see more
