Purpose: Maturation of the ability to recognize target speech in the presence of a two-talker speech masker extends into early adolescence. This study evaluated whether children benefit from differences in fundamental frequency (f[subscript o]) contour depth between the target and masker speech, a cue that has been shown to improve recognition in…

Purpose: Sleep-based memory consolidation has been shown to facilitate perceptual learning of atypical speech input including nonnative speech sounds, accented speech, and synthetic speech. The current research examined the role of sleep-based memory consolidation on perceptual learning for noise-vocoded speech, including maintenance of learning…

Purpose: This study investigates whether crosslinguistic effects on auditory word recognition are modulated by the quality of the auditory signal (clear and noisy). Method: In an online experiment, a group of Spanish--English bilingual listeners performed an auditory lexical decision task, in their second language, English. Words and pseudowords…

This study evaluated the role of Nigerian print media in bringing the health hazards of noise pollution to public awareness through the presentation of stories. "The Guardian," "Punch," and "Vanguard" newspapers were content analyzed to ascertain the framing, volume, prominence, frequency, and genre of noise pollution…

This study uses a qualitative methodology. The objective was to examine a musical instrument for teaching the creation and acoustic characteristics of Guhu of the Zhuang ethnic group in Guangxi, China, about shape and structure to summarize raw materials, craftsmanship, and process of Guhu, then measure by acoustic instruments, conclude the…

As an introduction to sound and vibration, the authors wanted their first-grade students to plan and conduct their own investigations. In this article, the authors share a series of investigations to help students explore the relationship between sound and vibration. By planning, creating, testing, adapting, and reflecting on the outcomes of the…

Purpose: The purpose of the study is to investigate the impacts of a surgical mask and a transparent mask on audio-only and audiovisual speech intelligibility in noise (i.e., 0 dB signal-to-noise ratio) in individuals with mild-to-profound hearing loss. The study also examined if individuals with hearing loss can benefit from using a transparent…

This study aims to investigate students' awareness of the level, causes and negative effects of noise in schools through the utilization of creative drama activities. The objective of this sample application is to contribute to the development of a more tranquil and peaceful school environment. A single case study design was employed for this…

The cross-sectional study explores the reasons behind students' avoidance of library reading. Of the 164 participants, the research uncovers a complex interplay between personal preferences, environmental influences, and social dynamics that shape reading behaviors. Contrary to expectations, students express a preference for classrooms settings…

Since Gisela Granena's influential work, LLAMA D v2, a sound recognition subtest of LLAMA aptitude tests, has been used as a measure of implicit learning aptitude in second language acquisition research. The validity of this test, however, is little known and the results of studies with this instrument have been somewhat inconsistent. In this…

Purpose: The aim of this study was to investigate infants' listening preference for emotional prosodies in spoken words and identify their acoustic correlates. Method: Forty-six 3- to-12-month-old infants (M[subscript age] = 7.6 months) completed a central fixation (or look-to-listen) paradigm in which four emotional prosodies (happy, sad, angry,…

Background: Previous research has found that high-frequency energy of speech signals decreased while wearing face masks. However, no study has examined the specific spectral characteristics of fricative consonants and vowels and the perception of clarity of speech in mask wearing. Aims: To investigate acoustic-phonetic characteristics of fricative…

We describe here a low-cost experiment for introductory physics students where they compare the physical properties of aluminum and steel by means of cantilever oscillations. This, in turn, allows the students to improve their physical intuition about these materials. Further, the students can apply their physics and mathematics knowledge and…

Purpose: Envelope following responses (EFRs) could be useful for objectively evaluating audibility of speech in children who are unable to participate in routine clinical tests. However, relative to adults, the characteristics of EFRs elicited by frequency-specific speech and their utility in predicting audibility in children are unknown. Method:…

Purpose: The aim of this study was to use acoustic and kinematic speech measures to characterize type of motor speech impairment--apraxia of speech (AOS) versus dysarthria--in individuals with four-repeat tauopathy (4RT)-associated syndromes, including nonfluent variant primary progressive aphasia (nfvPPA), primary progressive AOS (PPAOS),…
