• Asymmetric temporal envelope encoding: Implications for within- and across-ear envelope comparison August 16, 2019
  The Journal of the Acoustical Society of America, Volume 146, Issue 2, Page 1189-1206, August 2019. Separating sound sources in acoustic environments relies on making ongoing, highly accurate spectro-temporal comparisons. However, listeners with hearing impairment may have varying quality of temporal encoding within or across ears, which may limit the listeners' ability to make spectro-temporal […]

• Objective assessment of cleft lip and palate speech intelligibility using articulation and hypernasality measures August 15, 2019
  The Journal of the Acoustical Society of America, Volume 146, Issue 2, Page 1164-1175, August 2019. Assessment of intelligibility is required to characterize the overall speech production capability and to measure the speech outcome of different interventions for individuals with cleft lip and palate (CLP). Researchers have found that articulation error and hypernasality have a […]

• Broadband acoustic scattering from oblate hydrocarbon droplets August 15, 2019
  The Journal of the Acoustical Society of America, Volume 146, Issue 2, Page 1176-1188, August 2019. Improved in situ quantification of oil in the marine environment is critical for informing models of fate and transport and evaluating the resiliency of marine communities to oil spills. Broadband acoustic backscatter has been used to quantify a variety […]

• Recognition of emotional prosody by Mandarin-speaking adults with cochlear implants August 15, 2019
  The Journal of the Acoustical Society of America, Volume 146, Issue 2, Page EL165-EL171, August 2019. To understand how cochlear implant processing affects emotional prosody recognition in tonal languages, how normal-hearing (NH) and cochlear-implanted (CI) adults identify four emotions (“angry,” “happy,” “sad,” and “neutral”) in short, semantically neutral, Mandarin sentences are compared. Depending on hearing […]

• Wind turbine audibility and noise annoyance in a national U.S. survey: Individual perception and influencing factors August 14, 2019
  The Journal of the Acoustical Society of America, Volume 146, Issue 2, Page 1124-1141, August 2019. With results from a nationwide survey sponsored by the U.S. Department of Energy, factors that affect outdoor audibility and noise annoyance of wind turbines were evaluated. Wind turbine and summer daytime median background sound levels were estimated for 1043 […]

• Exact and approximate analytical time-domain Green's functions for space-fractional wave equations August 14, 2019
  The Journal of the Acoustical Society of America, Volume 146, Issue 2, Page 1150-1163, August 2019. The Chen-Holm and Treeby-Cox wave equations are space-fractional partial differential equations that describe power law attenuation of the form [math]. Both of these space-fractional wave equations are causal, but the phase velocities differ, which impacts the shapes of the […]

• Factors affecting the intelligibility of high-intensity-level-based speech August 14, 2019
  The Journal of the Acoustical Society of America, Volume 146, Issue 2, Page EL151-EL157, August 2019. The present work examined factors affecting the intelligibility of high-intensity-level-based speech. Mandarin sentences were processed to contain only high-intensity segments confined by a 5-dB selected intensity range (SIR), with other segments replaced by noise. The processed stimuli were presented […]

• On the loudness of low-frequency sounds with fluctuating amplitudes August 14, 2019
  The Journal of the Acoustical Society of America, Volume 146, Issue 2, Page 1142-1149, August 2019. Some environmental sounds have strong amplitude fluctuations that may affect their perceived loudness and annoyance. This study assessed the effect of beat rate (fb) and center frequency (fc) on the loudness of low-frequency beating tones. The loudness of two-tone […]

• Fast qualitative two-dimensional mapping of ultrasound fields with acoustic cavitation-enhanced ultrasound imaging August 14, 2019
  The Journal of the Acoustical Society of America, Volume 146, Issue 2, Page EL158-EL164, August 2019. Characterization of ultrasound fields is a routine procedure for both diagnostic and therapeutic ultrasound. Quantitative field mapping with a calibrated hydrophone and multi-axis positioning system can be difficult and time consuming. In this study, the use of acoustic cavitation […]
