    Abstract: During the COVID-19 pandemic, changes in vessel activity and associated noise have been reported globally. Sarasota Bay is home to a large and increasing number of recreational vessels as well as a long-term resident community of bottlenose dolphins, Tursiops truncatus. Data were analyzed from two hydrophones to compare the soundscape during the COVID-19 pandemic to previous years (March–May 2020 and 2018/2019). Hourly metrics were calculated: vessel passes, 95th percentile sound levels [125 Hz and 16 kHz third octave bands (TOBs), and two broader bands: 88–1122 Hz and 1781–17 959 Hz], and dolphin whistle detection to understand changes in vessel activity and the effect on wildlife. Vessel activity increased during COVID-19 restrictions by almost 80% at one site and remained the same at the other site. Of the four sound level measures, only the 125 Hz TOB and 88–1122 Hz band increased with vessel activity at both sites, suggesting that these may be appropriate measures of noise from rapid pass-bys of small vessels in very shallow ( & lt;10 m) habitats. Dolphin whistle detection decreased during COVID-19 restrictions at one site but remained the same at the site that experienced increased vessel activity. The results suggest that pandemic effects on wildlife should not be viewed as homogeneous globally.

    Abstract: Tropical cyclones are severe weather systems which can potentially have a large effect on marine ecosystems through direct or indirect effects. In June 2012, Tropical Storm Debby formed in the Gulf of Mexico and had impacted coastal Florida including Tampa Bay. Acoustic recorders were deployed during the storm at a shallow inshore location inside Tampa Bay (Boca 2) and a location offshore in the Gulf of Mexico (Gulf 1). The soundscape before (17–21 June), during (22–26 June) and after (27 June–3 July) Tropical Storm Debby was investigated in two ways: third-octave spectral analysis of root-mean-square sound pressure levels and the identification and quantification of fish sounds in spectrograms. Single-factor ANOVAs indicated a significant increase in ambient noise analyzed in third-octave bands during the storm at both sites (p & lt; 0.001), and an overall decrease in fish sound production during the storm at both sites (p & lt; 0.001). Several species-specific sound production patterns were also found which correlated with the storm’s passage. The changes in ambient noise and biological vocalization was short-lived and returned back to normal within 48 h of the storm. This study is one of three studies to examine the effects of tropical cyclone on marine soundscapes, and the only study to identify sound production to the species level. Furthermore, the results from this study provide important information on the effects of tropical storms on marine communities and the fast rate of recovery after these storms.

    Abstract: When synthetic fricative noises from an [∫] − [s] continuum are followed by [a] and [u] , listeners perceive more instances of [s] in the context of [u] [V. A. Mann and B. H. Repp, Perc. Psychophys. 28, 213–228 (1980)]. This perceptual context effect presumably reflects adjustment for the coarticulatory effects of rounded vowels on preceding fricatives. We have begun to examine the development of this effect, asking children to label stimuli from “save”-“shave” and “sue”-“shoe” continua, constructed by following noises from an [∫] and [s] continuum with periodic portions excerpted from natural tokens of “shave” and “shoe.” The subjects include normal adults, 5-, 7-, and 9-year-old children who correctly produce both [∫] and [s], and 7-year-olds who misarticulate these fricatives. Thus far we have found that the magnitude of the vocalic context effect is typically greater for adults, yet children at all ages show a significant effect whose magnitude is not a function of age. These findings, to be supplemented with those obtained from the misarticulating children, may clarify the developmental basis of listeners' tacit knowledge of coarticulation.

    Abstract: When synthetic noise replaces the natural friction in FV syllables and VF syllables, the influence of the vocalic segment on the perception of the noise as /s/ or /∫/ is greater for the FV syllables [S. D. Soli and V. A. Mann, J. Acoust. Soc. Am. Suppl. 1 71, S75 (1982)]. The acoustic and articulatory bases of this perceptual asymmetry were examined. Mean formant tracks displaying confidence intervals and amplitudes were computed for natural FV and VF syllables, where F = /∫/ and /s/, and V = /ɑ/ and /u/. FV and VF transitions were equally stable, although FV transitions exhibited larger coarticulatory differences due to fricative context. FV transitions also occurred during the highest amplitude portion of the vocalic segment, while VF transitions occurred as voicing amplitude was decreasing rapidly before the upcoming voiceless fricative. These acoustic differences would lead to larger vowel context effects for FV syllables. Thus the perceptual asymmetries appear to be a consequence of differences in the organization and timing of the supralaryngeal and laryngeal events which produce initial and final voiceless fricatives.
