Critical bandwidth measurements and sensitivity prediction from the acoustic reflex test results were obtained on 20 adult normal-hearing and two groups of 10 adult hearing impaired Ss each representing mild-to-moderate and severe hearing loss. (Author)

Discusses the need for quick access to stored musical sounds for effective music learning, and describes random access audio hardware designed for use with the PLATO system. Examples are presented and five pedogogical principles derived are discussed. (Author/RAO)

An electrical engineer and phoneticist has taught himself to read voiceprints, spectrograms that display a plot of the sound frequency of speech against time. This technique may prove useful in training the deaf to read voiceprints or to mimic natural speech. (BB)

Provides an apparatus for the analysis and evaluation of television by categorizing the existential media factors such as light, two- and three-dimensional screen space, time-motion, and sound. The correlation of one factor, time, with experiental phenomena such as instantaneousness and irrevocability of the moment and the complexity of the…

Allophonic variations in the quality and voicelessness of British English Received Pronunciation /1/ were investigated, largely through their acoustic correlates as revealed by spectrography. (Author/RM)

The cry sounds of 12 well-nourished and 12 malnourished male infants were compared using behavioral and acoustic measures. (BRT)

The timbre of various Sonicguide (an ultar-sonic binaural device mounted in a spectacle frame) signals was measured and analyzed by a "Sona-Graph" (sound spectral analyzer) to aid/mobility training of blind Ss. (Author/MH)

Discusses experiments that investigated the sources of knowledge that are employed in spoken word identification. The interactive assumption that normal spoken word identification processes require the presence of semantic and syntactic context and the special status given to word-initial acoustic-phonetic information in cohort theory were…

Localization acuity was examined by determining the smallest sound shift off midline and along the horizontal axis that infants 6-18 months could reliably discriminate. As their age increased, infants demonstrated a finer partitioning of auditory space along the horizontal axis. (PCB)

Reviews the potential of a data acquisition system for illustrating the nature and significance of ideas in digital signal processing. Focuses on the fast Fourier transform and the utility of its two-channel format, emphasizing cross-correlation and its two-microphone technique of acoustic intensity measurement. Includes programing format. (ML)

Investigates the relation between neonatal cry features elicited by painful circumcision procedures and the perceived urgency of those cries. (HOD)

Develops a method of analyzing and describing the acoustic properties of fricatives, which consists of making frequency spectra using the Fast Fourier Transform and then analyzing the spectra in terms of critical bands. The six fricatives of Chinese are analyzed by this method, and comparison with other languages is made. (SED)

Sound, like light, travels in waves. Young students (grades K-4) learn about the amazing journey of sound--from the source that creates the sound to the mechanics of the ear that enable it to be heard. Children discover why sound needs a "medium" to travel, why there is no sound in space, and how certain animals are able to…

The present study examines the effects of two common stresses, noise and sleep loss, on task performance. (Author/RK)

This study investigates the influence on recognition memory of the perceptual organization of the learning material both at the time it is studied and when it is tested. (Author)
