  • Doppler chirplet transform for the velocity estimation of a fast moving acoustic source of discrete tones January 18, 2019
    The Journal of the Acoustical Society of America, Volume 145, Issue 1, Page EL34-EL38, January 2019. An extended chirplet transform method termed as Doppler chirplet transform is proposed to estimate the velocity of a discrete tone source in uniform linear motion. This method directly uses the relation of the observed instantaneous frequency to the source […]

  • Tympanic membrane surface motions in forward and reverse middle ear transmissions January 18, 2019
    The Journal of the Acoustical Society of America, Volume 145, Issue 1, Page 272-291, January 2019. Characterization of Tympanic Membrane (TM) surface motions with forward and reverse stimulation is important to understanding how the TM transduces acoustical and mechanical energy in both directions. In this paper, stroboscopic opto-electronic holography is used to quantify motions of […]

  • Analysis and experimental validation of longitudinally composite ultrasonic transducers January 18, 2019
    The Journal of the Acoustical Society of America, Volume 145, Issue 1, Page 263-271, January 2019. The longitudinally cascaded piezoelectric ultrasonic transducer is studied which is composed of two longitudinally sandwiched piezoelectric transducers connected together mechanically in series and electrically in parallel. When the losses and load are taken into account, the electromechanical equivalent circuit […]

  • Deposition of polydisperse gas suspensions with nonlinear resonance oscillations in a closed tube January 18, 2019
    The Journal of the Acoustical Society of America, Volume 145, Issue 1, Page EL30-EL33, January 2019. The characteristics of the deposition of a polydisperse gas suspension (tobacco smoke) in a closed tube in the mode of transition to shock waves at the first natural frequency are studied experimentally. The natural deposition of tobacco smoke continues […]

  • Acoustic perfect absorbers via Helmholtz resonators with embedded apertures January 18, 2019
    The Journal of the Acoustical Society of America, Volume 145, Issue 1, Page 254-262, January 2019. Acoustic perfect absorption via a structure with deep subwavelength thickness is of great and continuing interest in research and engineering. This study analytically and experimentally investigates acoustic systems based on Helmholtz resonators which have embedded-apertures. The strategy of embedding […]

  • Thickness dependences of acoustic bandgaps with different generation mechanisms in phononic crystals immersed in water January 16, 2019
    The Journal of the Acoustical Society of America, Volume 145, Issue 1, Page EL25-EL29, January 2019. The thickness dependences of acoustic bandgaps were theoretically and experimentally investigated in two-dimensional phononic crystals (PCs) immersed in water. The acoustic pressure transmission coefficients were measured as a function of the PC thickness in order to understand the characteristics […]

  • The approximate constant [math] and linearized reflection coefficients based on the generalized fractional wave equation January 16, 2019
    The Journal of the Acoustical Society of America, Volume 145, Issue 1, Page 243-253, January 2019. The fractional parameter in a generalized fractional model is set to control the degree of absorption. However, it does not have an explicit physical meaning, even though it may be estimated from seismic data. Therefore, it is necessary to […]

  • Geometric calibration of very large microphone arrays in mismatched free field January 15, 2019
    The Journal of the Acoustical Society of America, Volume 145, Issue 1, Page 215-227, January 2019. Large microphone arrays are an efficient means for source localization thanks to a wide aperture and a great number of sensors. When such arrays are deployed in situ, accurate geometric calibration becomes essential to obtain the microphone positions. In […]

  • Forward masking enhances the auditory brainstem response in the free-tailed bat, Tadarida brasiliensis, during a critical time window for sonar reception January 15, 2019
    The Journal of the Acoustical Society of America, Volume 145, Issue 1, Page EL19-EL24, January 2019. Forward masking is a widespread auditory phenomenon in which the response to one sound transiently reduces the response to a succeeding sound. This study used auditory brainstem responses to measure temporal masking effects in the free-tailed bat, Tadarida brasiliensis. […]

  • A statistical method for the evaluation of long term trends in underwater noise measurements January 15, 2019
    The Journal of the Acoustical Society of America, Volume 145, Issue 1, Page 228-242, January 2019. Deep ocean ambient sound levels have been the subject of recent studies, with particular interest in the identification of long term trends. This paper describes a statistical method for performing long term trend analysis and uncertainty evaluation of the […]
