Purpose: The purpose of this study was to explore potential differences in suprathreshold auditory function among native and nonnative speakers of English as a function of age. Method: Retrospective analyses were performed on three large data sets containing suprathreshold auditory tests completed by 5,572 participants who were self-identified…

Soundscapes engender historical, cultural, social, and aesthetic meanings through acoustical qualities that reflect a community's lived experiences. In this article, we propose music lesson ideas that help students appreciate and embrace their sociocultural heritage--by creating, performing, and listening to soundscapes that are representative of…

Nonverbal sound effects, such as background music and sound enhancements, have been widely used in children's eBooks; however, the impact of these effects on children's language learning remains inconclusive. This study examined Mandarin-English bilingual children's attention on sound-enhanced words during static eBook viewing. Fifty-seven 4-5…

Purpose: Hypernasality and atypical voice characteristics are common features of dysarthric speech due to amyotrophic lateral sclerosis (ALS). Existing acoustic measures have been developed to primarily target either hypernasality or voice impairment, and the effects of co-occurring hypernasality-voice problems on these measures are unknown. This…

Purpose: The aim of the study was to examine associations between speaking fundamental frequency (f[subscript os]), vowel formant frequencies (F), listener perceptions of speaker gender, and vocal femininity-masculinity. Method: An exploratory study was undertaken to examine associations between f[subscript os], F[subscript 1]-F[subscript 3],…

Purpose: The primary aim of this study was to obtain high-quality acoustic normative data in natural field environments for female voices. A secondary aim was to examine acoustic measurement variability in field environments. Method: This study employed a within-subject repeated-measures experimental design that included 45 young female adults…

Purpose: The aims of this study were (a) to longitudinally assess environmental sound recognition (ESR) before and after cochlear implantation in a sample of postlingually deafened adults and (b) to assess the extent to which spectro-temporal processing abilities influence ESR with cochlear implants (CIs). Method: In a longitudinal cohort study,…

Purpose: Speech production requires the combined efforts of feedforward control and feedback control subsystems. The primary purpose of this study is to explore whether the relative weighting of auditory feedback control is different between the first language (L1) and the second language (L2) production for late bilinguals. The authors also make…

By building a schlieren optical system, the visualization of a 40 KHz sound wave is realized. By using the schlieren system, the demonstration of acoustic reflection, interference and diffraction can be easily realized. At the same time, the visual acoustic field provides another simple way for the measurement of sound velocity. In this paper, the…

With COVID-19 having disrupted K-12 and college education for more than a year now, President Biden has prioritized reopening the majority of K-8 schools within his first 100 days. In addition, the President's American Rescue Plan would provide $170 billion for K-12 schools, colleges, and universities, which could be used for a wide array of…

The power and precision with which humans link language to cognition is unique to our species. By 3-4 months of age, infants have already established this link: simply listening to human language facilitates infants' success in fundamental cognitive processes. Initially, this link to cognition is also engaged by a broader set of acoustic stimuli,…

In the violin, the fundamental air cavity mode (the A0 mode) is associated with the sound radiated by the f-holes. The dependences of the sound velocity of the A0 frequency on gaseous temperature and mass were investigated. It was found that the frequency of the A0 mode changed, depending on the molecular weight and the temperature of the gas…

Purpose: This study aims to examine the development of auditory selective attention to speech in noise by examining the ability of infants to prefer child-directed speech (CDS) over time-reversed speech (TRS) presented in "on-channel" and "off-channel" noise. Method: A total of 32 infants participated in the study. Sixteen…

Reading skills are usually assessed in silent conditions, but children often experience noisy educational settings. Effects of auditory distraction on children's reading skills remain relatively unexplored. The present study investigates the influence of two features of background speech--intelligibility and loudness--on children's reading speed…

Kundt's tube is a popular experiment commonly used in schools, in which standing sound waves are made visible inside a glass tube. A fine powder is stirred up in areas of high sound particle velocities, so that one can measure the wavelength of the sound waves by examining the patterns created. In this way, the 'invisible' can be made visible.…
