Machine learning is the process of learning functional relationships between measured signals and some output of interest. This #AcousticsToday article provides an introduction to machine learning with a few conceptual explanations of techniques. https://t.co/eCPau8O3z9 https://t.co/PFWRVayFjp acousticsorg photo

  • Unsupervised repetition enables rapid perceptual learning November 23, 2021
    The Journal of the Acoustical Society of America, Volume 150, Issue 5, Page 3964-3975, November 2021. This study examined how listeners disambiguate an auditory scene comprising multiple competing unknown sources and determine a salient source. Experiment 1 replicated findings from McDermott, Wrobleski, and Oxenham. [(2011). Proc. Natl. Acad. Sci. U. S. A. 108(3), 1188–1193] using […]

  • Contributions of gravity waves in the ocean to T-phase excitation by earthquakes November 23, 2021
    The Journal of the Acoustical Society of America, Volume 150, Issue 5, Page 3999-4017, November 2021. The generation of T waves in a deep ocean by an earthquake in its epicentral region is often observed, but the mechanism of the excitation of the acoustic waves travelling horizontally with the speed of sound remains controversial. Here, […]

  • Echolocation variability of franciscana dolphins (Pontoporia blainvillei) between estuarine and open-sea habitats, with insights into foraging patterns November 23, 2021
    The Journal of the Acoustical Society of America, Volume 150, Issue 5, Page 3987-3998, November 2021. Environmental and ecological factors can trigger changes in the acoustic repertoire of cetaceans. This study documents the first use of a well-established passive acoustic monitoring device (C-POD) to analyze echolocation sounds and behavior of franciscana dolphins in different habitats: […]

  • A causal and talker-independent speaker separation/dereverberation deep learning algorithm: Cost associated with conversion to real-time capable operation November 23, 2021
    The Journal of the Acoustical Society of America, Volume 150, Issue 5, Page 3976-3986, November 2021. The fundamental requirement for real-time operation of a speech-processing algorithm is causality—that it operate without utilizing future time frames. In the present study, the performance of a fully causal deep computational auditory scene analysis algorithm was assessed. Target sentences […]

  • Perception of gender in children's voices November 23, 2021
    The Journal of the Acoustical Society of America, Volume 150, Issue 5, Page 3949-3963, November 2021. To investigate the perception of gender from children's voices, adult listeners were presented with /hVd/ syllables, in isolation and in sentence context, produced by children between 5 and 18 years. Half the listeners were informed of the age of the […]

  • Impact of data augmentation on supervised learning for a moving mid-frequency source November 22, 2021
    The Journal of the Acoustical Society of America, Volume 150, Issue 5, Page 3914-3928, November 2021. Two residual networks are implemented to perform regression for the source localization and environment classification using a moving mid-frequency source, recorded during the Seabed Characterization Experiment in 2017. The first model implements only the classification for inferring the seabed […]

  • A free field recovery technique based on the boundary element method and three-dimensional scanning measurements November 22, 2021
    The Journal of the Acoustical Society of America, Volume 150, Issue 5, Page 3929-3948, November 2021. The boundary element method- (BEM-) based free field recovery technique (FFRT) has been proposed to recover the free field radiated by an arbitrarily shaped source from the mixed field that would be measured in a noisy environment. However, that […]

  • Diagnostic ultrasound imaging of the lung: A simulation approach based on propagation and reverberation in the human body November 22, 2021
    The Journal of the Acoustical Society of America, Volume 150, Issue 5, Page 3904-3913, November 2021. Although ultrasound cannot penetrate a tissue/air interface, it images the lung with high diagnostic accuracy. Lung ultrasound imaging relies on the interpretation of “artifacts,” which arise from the complex reverberation physics occurring at the lung surface but appear deep […]

  • The response of common carp (Cyprinus carpio) to insonified bubble curtains November 22, 2021
    The Journal of the Acoustical Society of America, Volume 150, Issue 5, Page 3874-3888, November 2021. Acoustic bubble curtains have been marketed as relatively low cost and easily maintained behavioural deterrents for fisheries management. Their energy efficiency can be improved by reducing air flow and exploiting bubble resonance. In a series of three flume experiments, […]
