Investigating the emotional impact of music listening has a long history. Indeed, reactions to subtle as well as obvious changes in music, whether inadvertent or deliberate, occupy a good deal of interest for the music researcher as well as the music educator. Regardless of the extremely subtle acoustic changes that are perceptible within almost…

Previous research has shown that English infants are sensitive to mispronunciations of vowels in familiar words by as early as 15-months of age. These results suggest that not only are infants sensitive to large mispronunciations of the vowels in words, but also sensitive to smaller mispronunciations, involving changes to only one dimension of the…

This paper aims to explain effects of acoustical environments in sound perception of hearing impaired people. Important aspects of sound and hearing impairment are explained. Detrimental factors in acoustic conditions for speech perception are mentioned. Necessary acoustic treatment in classrooms and use of FM systems to eliminate these factors…

Pitch is a psychoacoustic construct crucial in the production and perception of speech and songs. This article is an exploration of the interface of speech and song performance of Chinese speakers. Although parallels might be drawn from the prosodic and sound structures of the linguistic and musical systems, perceiving and producing speech and…

I have been tinkering with ultrasonic transducers once more. In earlier notes I reported on optics-like experiments performed with ultrasonics, described a number of ultrasonic interferometers, and showed how ultrasonic transducers can be used for Fourier analysis. This time I became interested in trying the technique of using two detectors in…

Individuals with developmental dyslexia are often impaired in their ability to process certain linguistic and even basic non-linguistic auditory signals. Recent investigations report conflicting findings regarding impaired low-level binaural detection mechanisms associated with dyslexia. Binaural impairment has been hypothesized to stem from a…

In this article, the author explores the digital artwork of Brian Evans, a composer-artist who creates visualizations of sound. Through the years Evans' love for music and visual art led him to explore ways to work concurrently with image and sound. Digital technology proved to be such a means. Digital technology is based upon the transcription of…

Purpose: To compare the effects of conventional amplification (CA) and digital frequency compression (DFC) amplification on the speech recognition abilities of candidates for a partial-insertion cochlear implant, that is, candidates for combined electric and acoustic stimulation (EAS). Method: The participants were 6 patients whose audiometric…

Phillips-Silver and Trainor (Phillips-Silver, J., Trainor, L.J., (2005). Feeling the beat: movement influences infants' rhythm perception. "Science", 308, 1430) demonstrated an early cross-modal interaction between body movement and auditory encoding of musical rhythm in infants. Here we show that the way adults move their bodies to music…

The general purpose of this research was to describe coarticulation across voiced stop consonant place of articulation in 10 children younger than 2 years of age. A total of 1,182 voiced stop CV productions was analyzed using the locus equation metric, which yielded 3 regression lines that described the relation of F2 onset and F2 vowel for /bV/,…

We explore in this study how infants may derive phonetic categories from adult input that are highly variable. Neural networks in the form of self-organizing maps (SOMs; Kohonen, 1989, 1995) were used to simulate unsupervised learning of Mandarin tones. In Simulation 1, we trained the SOMs with syllable-sized continuous F[subscript 0] contours,…

Teaching Science can only be successful if we are able to answer the challenges of the 21st century. Teaching Physics, Chemistry and Biology with the traditional methods is unintelligible and considered unnecessary for most students. This situation needs to be changed. Students can only develop their abilities and skills to the full extent and can…

Hearing loss is the number one disability in the United States. It cannot be assumed, however, that all people with hearing loss have similar needs. Most individuals with hearing loss do not use sign language, and people who are hard of hearing (HOH) are often grouped together with people who are Deaf and referred to as "deaf" or "hearing…

This review surveys documents and journal articles previously announced in RIE and CIJE that deal with the principles and techniques of sound transmission and control, particularly as they relate to school environments. School planners and administrators are advised that excessive acoustical insulation costs may be avoided by early decisions…

This report examines the problem of acoustic inadequacy in the classroom, how it affects students and teachers, and possible solutions. It explains how to predict classroom adequacy for communication by assessing the level of speech in competition with other noise, and the level of that competing noise itself in terms of reverberation that allows…
