• Waveguide dispersion curves identification at low-frequency using two actuators and phase perturbations October 15, 2019
  The Journal of the Acoustical Society of America, Volume 146, Issue 4, Page 2443-2451, October 2019. Dispersion curves of fluid-filled elastic-tubes are used for non-destructive measurement of material acoustic properties. The underlying physics leads to a singular numerical procedure when several modes or long-wavelength scenarios take part in the tube dynamics. The literature describes several […]

• Contrast-enhanced ultrasound imaging using pulse inversion spectral deconvolution October 15, 2019
  The Journal of the Acoustical Society of America, Volume 146, Issue 4, Page 2466-2474, October 2019. A contrast-enhanced ultrasound (CEUS) imaging approach, termed pulse inversion spectral deconvolution (PISD), is introduced. The approach uses two Gaussian-weighted Hermite polynomials to form two inverted pulse sequences. The two inversed pulses are then used to filter ultrasound (US) backscattered […]

• Development of temporal auditory processing in childhood: Changes in efficiency rather than temporal-modulation selectivity October 15, 2019
  The Journal of the Acoustical Society of America, Volume 146, Issue 4, Page 2415-2429, October 2019. The ability to detect amplitude modulation (AM) is essential to distinguish the spectro-temporal features of speech from those of a competing masker. Previous work shows that AM sensitivity improves until 10 years of age. This may relate to the […]

• Short-range propagation characteristics of airgun pulses during marine seismic reflection surveys October 15, 2019
  The Journal of the Acoustical Society of America, Volume 146, Issue 4, Page 2430-2442, October 2019. Marine seismic reflection surveys use airguns to generate repetitive high energy sound signals to image the structure of the seafloor. To better mitigate against the impact of airgun pulses on marine mammals, safety criteria are defined to ensure marine […]

• Use of magnetic resonance image registration to estimate displacement in the human earcanal due to the insertion of in-ear devices October 15, 2019
  The Journal of the Acoustical Society of America, Volume 146, Issue 4, Page 2452-2465, October 2019. In-ear devices are used in a wide range of applications for which the device's usability and/or efficiency is strongly related to comfort aspects that are influenced by the mechanical interaction between the device and the walls of the earcanal.

• Characterization of sound scattering using near-field pressure and particle velocity measurements October 14, 2019
  The Journal of the Acoustical Society of America, Volume 146, Issue 4, Page 2404-2414, October 2019. The acoustic properties of surfaces are commonly evaluated using samples of finite size, which generate edge diffraction effects that are often disregarded. This study makes use of sound scattering theory to characterize such finite samples. In a given sound […]

• Adaptive block forward and backward stagewise orthogonal matching pursuit algorithm applied to rolling bearing fault signal reconstruction October 14, 2019
  The Journal of the Acoustical Society of America, Volume 146, Issue 4, Page 2385-2394, October 2019. In the process of block compressed sensing (CS) applied to the rolling bearing fault signal, the reconstruction accuracy of the signal is low due to the large difference in sparsity between blocks and the unreasonable components of reconstruction support […]

• Calculation of acoustic radiation modes by using spherical waves and generalized singular value decomposition October 14, 2019
  The Journal of the Acoustical Society of America, Volume 146, Issue 4, Page EL347-EL351, October 2019. Acoustic radiation modes (ARMs) have been widely used in noise control engineering owing to their convenient sound-power characteristics. However, the evaluation of ARMs for non-regular structures can be computationally intensive: it usually involves solving the boundary integral equation (BIE) […]

• A tutorial example of duct acoustics mode detections with machine-learning-based compressive sensing October 14, 2019
  The Journal of the Acoustical Society of America, Volume 146, Issue 4, Page EL342-EL346, October 2019. Acoustic beamforming and mode detections by means of machine learning have potential advantages over conventional strategies, e.g., first-principle based forward acoustic models may be replaced by neural networks. In this work, the machine-learning-based strategy is presented for aeroengine duct […]
