Purpose: The objective of the current study was to investigate the effects of age and vocal loading on the respiratory and laryngeal systems. Method: Fourteen younger (M = 20 years) and 13 older (M = 75 years) healthy individuals participated in a 40-min vocal loading challenge in the presence of 70-dB background noise. Respiratory kinematic and…

Purpose: The present study aimed to establish normative data for wideband absorbance (WBA) measured at tympanometric peak pressure (TPP) and 0 daPa and to assess the test-retest reliability of both measurements in healthy neonates. Method: Participants of this cross-sectional study included 99 full-term neonates (165 ears) with mean chronological…

The purpose of this paper is to demonstrate how the Doppler effect can be analysed to deduce information about a moving source of sound waves. Specifically, we find the speed of a car and the distance of its closest approach to an observer using sound recordings from smartphones. A key focus of this paper is how this can be achieved in a…

Purpose: Behavioral speech modifications have variable effects on the intelligibility of speakers with dysarthria. In the companion article, a significant relationship was found between measures of speakers' baseline speech and their intelligibility gains following cues to speak louder and reduce rate (Fletcher, McAuliffe, Lansford, Sinex, &…

In a dramatic physics demonstration, a professional flutist produces four resonances with a 12 ounce Boylan soda bottle solely through her breath control. The 22cm bottle acts like a Helmholtz resonator for the lowest pitch. The three higher pitches fall near the 3rd, 5th, and 7th harmonics for a 22cm closed pipe. A video of this remarkable feat…

Purpose: The strength of the relationship between vowel centralization measures and perceptual ratings of dysarthria severity has varied considerably across reports. This article evaluates methods of acoustic-perceptual analysis to determine whether procedural changes can strengthen the association between these measures. Method: Sixty-one…

Web-based applications in education seem to be increasing day by day. As in all fields of education, web-based teaching practices are being developed to make the subjects learn better in science. The web-based instruction on science education for 6th-grade students, light and sound unit, a reflection of light was designed according to Dick and…

Purpose: Conversation training therapy (CTT) is the 1st voice therapy approach to eliminate the traditional therapeutic hierarchy and use patient-driven conversation as the sole therapeutic stimulus. The purpose of this investigation was to determine the efficacy of CTT compared to standard-of-care voice therapy approaches for the treatment of…

Compared to low-variability training, high-variability training leads to better learning outcomes and supports generalization of learning. However, it is unclear whether the learning advantage is driven by multiple talkers or by enhanced acoustic variability across target sounds. The current study addressed this issue in nonnative production…

Previous studies have demonstrated that active engagement in musical activities benefits auditory and cognitive processing. However, it is still unclear whether musical experience improves domain-general mechanisms reflected in superior functioning in language or the enhancement is selective and limited to musical abilities. In the present study,…

The current study longitudinally examined a crucial individual difference variable -- i.e. awareness (operationalized as explicit attention and articulatory knowledge) -- in adult second language (L2) speech learning in the context of 40 Japanese learners' English /[alveolar approximant]/ pronunciation development in an EFL classroom. The…

Purpose and Method of Study: The purpose of this causal-comparative quantitative study was to investigate the effect of classroom audio distribution (CAD) technology implementation on the percentage of elementary school students in special education as a potential strategy to improve the learning process for at-risk students. Fourteen K-5 and K-6…

Purpose: General language abilities of children with cochlear implants have been thoroughly investigated, especially at young ages, but far less is known about how well they process language in real-world settings, especially in higher grades. This study addressed this gap in knowledge by examining recognition of sentences with complex syntactic…

Children who are deaf or hard-of-hearing (D/HH) learning in inclusive educational settings must be aware of how well they hear and understand spoken language to advocate for themselves. This study explored elementary-age children's self-reported listening abilities using thematic analysis of brief interviews. Participants were 16 D/HH and 16…

The present study reports on the development of a questionnaire that evaluates children's experiences of their physical classroom environment, activities and interactions. It also explores the psychometric properties of the questionnaire and how acoustical characteristics of the classroom, class size and student characteristics (age, sex and…
