Reported were estimates of hearing levels of noninstitutionalized children aged 6 to 11 years in the United States in relation to their demographic and socioeconomic background. Findings are results of individual monaural pure-tone air-conduction audiometric tests, conducted as part of the Health Examination Survey of 1963-65. In the survey 7,119…

The auditory perception skills of 32 learning disabled (LD) and 32 non LD culturally different elementary pupils were compared. Results of the Wepman Auditory Discrimination Test and three subtests of the Illinois Test of Psycholinguistic Abilities indicated consistent differences between the two groups on all four measures of auditory perception…

Investigates the principles underlying the perception of vowel stimuli. The results support Chistovich's claim. When judging the distance between synthetic vowel stimuli, speakers refer to the phonemic structure of their native language. They determine the phonemes closest to the stimuli and then compare the phonemes and not the stimuli…

Recently, Nilsson (1975) challenged Watkins's conclusion that the modality effect is a post-categorical phenomenon. In this brief reply the authors argued that Nilsson's findings are not only consistent with the postcategorical interpretation but also inconsistent with the precategorical interpretation.

An examination of the hearing mechanism and some of the factors involved in helping problems may offer encouragement for a regular schedule of hearing maintenance. It may also help music educators to become more aware and understanding of their own and students' hearing as it affects musical behavior. (Author)

The study determined whether eight undergraduate normal listeners, presented with filtered speech, would produce consonant confusions similar to those previously reported for the hearing-impaired listener. (Author/SBH)

Research by Posner and Mitchell (1967) was used to investigate levels of noise processing in testing subjects' ability to "gate out" the processing of irrelevant and unwanted material. Three experiments are reported in which subjects had to judge whether two letters were the "same" or "different". Noise elements were included to test attention…

Describes studies of voice onset time in Spanish and an acoustic feature termed presence versus absence of an abrupt consonant onset. It is suggested that this feature may be used by the Spanish listener in making a perceptual distinction between voiced and voiceless stop consonants in multiple environments. (Author/KM)

An experiment is reported in which 25 listeners were presented with pairs of stimuli of equal duration, but differing in fundamental frequency, and were asked to decide which of the two stimuli was longer. (Author/RM)

Discrimination scores among 556 listeners from 14 to 98-years-old with flat sensorineural hearing losses (742 ears) were analyzed in terms of degree of hearing impairment and subject age. (Author/IM)

An analysis of rhythm in French. The research project concentrated on two points: the perception of a "click" superimposed on an utterance and the reproduction of the click by a knock simultaneous with the stimulus. Conclusions based on linguistic and non-linguistic aspects are drawn. (Text is in French.) (AMH)

Results indicated that significantly more time is needed to perceive tempo increase than tempo decrease, uneven rhythm then even rhythm, and melody alone than melody with accompaniment. Furthermore, significant interaction effects involving beat locations of tempo change suggest that differential groupings may be a factor in tempo discrimination.…
