• Sensitivity analysis of pinna morphology on head-related transfer functions simulated via a parametric pinna model April 12, 2021
  The Journal of the Acoustical Society of America, Volume 149, Issue 4, Page 2559-2572, April 2021. The head-related transfer function (HRTF) defines the acoustic path from a source to the two ears of a listener in a manner that is highly dependent on direction. This directional dependence arises from the highly individual morphology of the […]

• Temperature-driven seasonal and longer term changes in spatially averaged deep ocean ambient sound at frequencies 63–125 Hz April 12, 2021
  The Journal of the Acoustical Society of America, Volume 149, Issue 4, Page 2531-2545, April 2021. The soundscape of the Northeast Pacific Ocean is studied with emphasis on frequencies in the range 63–125 Hz. A 34-year (1964–1998) increase and seasonal fluctuations (1994–2006) are investigated. This is achieved by developing a simple relationship between the total radiated […]

• Data augmentation for the classification of North Atlantic right whales upcalls April 12, 2021
  The Journal of the Acoustical Society of America, Volume 149, Issue 4, Page 2520-2530, April 2021. Passive acoustic monitoring (PAM) is a useful technique for monitoring marine mammals. However, the quantity of data collected through PAM systems makes automated algorithms for detecting and classifying sounds essential. Deep learning algorithms have shown great promise in recent […]

• European starlings (sturnus vulgaris) discriminate rhythms by rate, not temporal patterns April 12, 2021
  The Journal of the Acoustical Society of America, Volume 149, Issue 4, Page 2546-2558, April 2021. Humans can perceive a regular psychological pulse in music known as the beat. The evolutionary origins and neural mechanisms underlying this ability are hypothetically linked to imitative vocal learning, a rare trait found only in some species of mammals […]

• Noise thresholds in harmonic series maskers April 9, 2021
  The Journal of the Acoustical Society of America, Volume 149, Issue 4, Page 2492-2503, April 2021. The presence of noise is a salient cue to the perception of breathiness and aspiration in speech sounds. The detection of noise within harmonic series (maskers) composed of unresolved components was found to depend on the fundamental frequency (fo) […]

• Acoustic backscattering observations from non-spherical gas bubbles with ka between 0.03 and 4.4 April 9, 2021
  The Journal of the Acoustical Society of America, Volume 149, Issue 4, Page 2504-2519, April 2021. The study of gas bubbles in liquid media is of importance in many areas of research. Gas bubbles are often studied using in situ measurement techniques; however, acoustic inversion techniques have also been used to extract physical properties of […]

• Characterization of topographic effects on sonic boom reflection by resolution of the Euler equations April 8, 2021
  The Journal of the Acoustical Society of America, Volume 149, Issue 4, Page 2437-2450, April 2021. The influence of topography on sonic boom propagation is investigated. The full two-dimensional Euler equations in curvilinear coordinates are solved using high-order finite-difference time-domain techniques. Simple ground profiles, corresponding to a terrain depression, a hill, and a sinusoidal terrain, […]

• Proximity resonances of water-entrained air bubbles near acoustically reflecting boundaries April 8, 2021
  The Journal of the Acoustical Society of America, Volume 149, Issue 4, Page 2477-2491, April 2021. The acoustic resonances of radiatively damped air bubbles in water near reflecting boundaries are investigated by representing the bubble and its image by two bubbles in a full space, ensonified by two incident fields. Results obtained using an analytic […]

• Multi-sensor integration for an assessment of underwater radiated noise from common vessels in San Francisco Bay April 8, 2021
  The Journal of the Acoustical Society of America, Volume 149, Issue 4, Page 2451-2464, April 2021. There is growing evidence that smaller vessels not required to broadcast data via the Automatic Identification System (AIS) contribute significant noise to urbanized coastal areas. The Marine Monitor (M2), a vessel tracking system that integrates AIS data with data […]
