    Abstract: Calibration methods and facilities have been employed to directly obtain sensitivities of an underwater acoustic vector receiver using two methods based on laser Doppler vibrometry. The vector receiver was first calibrated in a standing wave tube over the frequency range 20 Hz to 2 kHz, where the oscillatory velocity of the water-air interface was measured to determine the sound particle velocity at the position of vector receiver based on waveguide theory. In the frequency range 2.5–10 kHz, the vector receiver was calibrated in an anechoic vessel with dimensions of 1.2 m diameter × 1.8 m length using wideband signals, with a laser Doppler vibrometer used to detect the oscillatory motion of a plastic pellicle, which was sufficiently thin to follow the acoustic particle motion. The uncertainties of the calibration using the optical method were estimated to be 0.7–0.8 dB at 95% confidence interval. The calibration results were compared with those obtained using a reciprocity method in a 50 m × 15 m × 10 m water tank and using a comparison method in a standing wave tube, and the largest deviation did not exceed 1.0 dB over the frequency range 20 Hz to 10 kHz.

    Acoustical Society of America (ASA) ; 2018

    Abstract: The conventional detection method has difficulty in detecting the narrowband signal in the noisy shallow water waveguide, because detection under the plane-wave model mismatches the shallow water waveguide. In this paper, a generalized likelihood ratio test based on mode-space beamfoming is proposed, considering the acoustic field in a shallow water waveguide can be characterized by normal mode model. Due to the otherness of the mode wavenumbers, the generalized likelihood ratio test model is constructed by mode-space beamforming. As the mode-space beamfoming has an ill-posed problem, we ignore the small eigenvalues of the coefficient matrix, and then has a benefit on the performance of detector. Theoretical analysis and simulation result validate the effectiveness of the proposed algorithm.

    Abstract: In this paper, an impedance matching underwater acoustic bend with pentamode microstructure is designed. The proposed bend is assembled by pentamode lattice. The effective density and compressive modulus of each unit cell can be tuned simultaneously, which are modulated to guarantee both the bending effect and high transmission. The standard deviations (SDs) of transmitted phase are calculated to quantitatively evaluate the degree of the distortion of the transmitted wavefront, while the transmission is calculated to appraise the degree of acoustic impedance matching. The low SDs and high transmission indicate that the designed bend has a nice broadband bending effect and is impedance-matched to water. This design has potential applications in underwater communication and underwater detection.

    Abstract: Tow ship noise seriously influence the detection and direction of arrival (DOA) estimation performance of towed array. Null steering beamforming(NSBF), inverse beamforming(IBF) and non-data based beam-space transformation(NDBBT) are applied to suppress interference of tow ship in this paper. These methods are evaluated according to the improvement of signal interference noise ratio and DOA estimation precision. Simulation and experimental results show that all three methods can suppress interference of tow ship effectively so as to improve DOA estimation precision. In addition, IBF and NDBBT do better in suppressing interference than NSBF.

    Effect of low intensity pulsed ultrasound on mesenchymal stem cells.

    Abstract: Low intensity pulsed ultrasound (LIPUS) has been used to accelerate tissue regeneration; however, the biological mechanisms of LIPUS induced regeneration is not completely understood. The aim for this study is to elucidate the mechanical effect generated by US for the stimulation of mesenchymal stem cells (MSCs). MSCs were cultured on flexible cell culture membranes and stimulated by US for 10 min daily with acoustic intensities of 0, 6, 13.5, and 22.5 W/cm2. Cell proliferation and viability were evaluated by direct cell count and Alamar Blue assay. Morphological evaluation was performed and cell-matrix interactions were evaluated. Cell-matrix interaction was analyzed by immunochemical staining of focal adhesion proteins. LIPUS enhanced cell proliferation at higher intensities and there was an increase in cell viability after 4 consecutive days of US treatment. No morphological changes were observed in all treatments. Expression of focal adhesion protein, vinculin, was enhanced after 3 consecutive days of ultrasound treatment. Studies of media agitation did not show any enhancement effect in cell proliferation or focal adhesion protein expression. The results validates that US is able to influence the cell matrix interaction. Application of higher acoustic pressure on cell growth environment can stimulate MSC proliferation and focal adhesion.
