In order to progress in the area of aeroacoustics, experimental measurements are
necessary. Not only are they required for engineering applications in acoustics and noise …

Acoustic waves are a possible reusable method to extinguish flames. Previous studies have
placed the sound source near the flame or have used standing waves to reach large enough …

Time reversal (TR) signal processing is an effective tool to exploit a reverberant environment
for the intentional focusing of airborne, audible sound. A previous room acoustics TR study …

Let us consider the deconvolution problem, ie to recover a latent source x (⋅) from the
observations y=[y 1,…, y N] of a convolution process y= x⋆ h+ η, where η is an additive …

Time reversal is a technique to focus wave energy to a selected point in space and time,
localize and characterize a source of wave propagation, and/or communicate information …

Time reversal (TR) focusing of airborne ultrasound in a room is demonstrated. Various
methods are employed to increase the amplitude of the focus. These methods include …

Time reversal (TR) is a signal processing technique often used to generate focusing at
selected positions within reverberant environments. This study investigates the effect of the …

Time Reversal (TR) is a technique that may be used to focus an acoustic signal at a
particular point in space. While many variables contribute to the quality of TR focusing of …

Time reversal focusing above an array of resonators creates subwavelength–sized features
when compared to wavelengths in free space. Previous work has shown the ability to focus …

In acoustics, time-reversal processing is commonly used to exploit multiple scatterings in
reverberant environments to focus sound to a specific location. Recently, the nonlinear …
