Waveform transition in the transient focusing field
In classical optics and acoustics, the focusing field for harmonic or monochromatic waves is charactenzed by a phenomenon of wave concentration and phase anomaly. For the transient focusing field, significant waveform deformation or waveform transition takes place in the vicinity of the focus. It is shown here theoretically and experimentally that the focusing of the transient wave is characten...
متن کاملTransfer function of the laser beam deflection probe for detection of cylindrical acoustic waves in a transverse arrangement
We examine detection of cylindrical acoustic waves by a laser beam probing the wave orthogonally to the symmetry axis. Considering the probe as a linear system transforming acoustic waveform into transient angular deflection of the probe beam we derive its transfer function.
متن کاملJoint spherical beam forming for directional analysis of reflections in rooms
Abstract: This contribution presents a new approach for analysing spatial directions in room impulse responses captured with source and receiver of adjustable directivity. A distinct peak in a room impulse response is usually associated with an acoustic path length of direct or reflected sound. Given the ability to modify the directivity of source and receiver by spherical beamforming, beam coe...
متن کاملComputation of Mode Radiation from a Generic Aeroengine Intake
The radiation of acoustic modes from an aeroengine intake duct is reviewed. The method is based upon a computational scheme which allows acoustic waves, propagating inside the intake duct of a generic aircraft engine, to be admitted into a computational domain that includes the duct section, the exit plane of the duct, and the surrounding flow. The method comprises three elements: a matching pr...
متن کاملInfluence of model parameter variability on the directivity filters of compact loudspeaker arrays
2845 Sound directivity control is made possible by a compact array of independently driven loudspeakers. Recently, a control system for such a multi-channel source based on its acoustic radiation modes has been proposed. These modes form an orthogonal set of velocity patterns on the source surface, and emerge from the eigendecomposition of a free-field radiation operator that depends on frequen...
