This study examined developmental effects in auditory perception of word-final /s/ in inflectional morpheme contexts as a function of high-frequency (HF) bandwidth with normal hearing 5-, 7-, 10-year-olds and adults. The higher detection thresholds and larger clarity rating variances for the youngest participants support the use of extended…

An investigation was conducted to identify the effects of exposure to selected entertainment environments on hearing threshold levels. Twenty-five normal hearing females were randomly assigned to one of the following five taped noise conditions: (1) a discotheque band, (2) a motor speedway, (3) a hotel dance band, (4) an amusement park, and (5) a…

Puretone auditory assessment of 21 adults with severe to profound mental retardation indicated that a bivariate plotting procedure of predicting hearing sensitivity from the acoustic reflexes should be included in an audiological test battery for this population. (CL)

Results indicated no significant differences between conditioning procedures in regard to obtained MRLs (minimum response levels) number of stimulus presentations required to establish MRL (discounting conditioning trials), and number of false-positive responses observed during control trial for 60 premature infants at one or two years of age.…

This study aimed to (a) investigate the effect of using a hearing aid in conjunction with a cochlear implant in opposite ears on speech perception in quiet and in noise, (b) identify the speech information obtained from a hearing aid that is additive to the information obtained from a cochlear implant, and (c) explore the relationship between…

The study presents normative data on Masking Level Difference (an improvement of the auditory processing of interaural time/intensity differences between signals and masking noises) for 90 learning disabled persons (4-35 years old). It was concluded that the MLD may quickly screen for auditory processing problems. (CL)

To investigate students' ability to generalize auditory skills, precourse to postcourse measures were compared for an auditory training group (N=42) and a control group (N=7) on three auditory discimination measures: (1) the training sentences, (2) related but nontrained sentences (decoy sentences), and (3) a modified rhyme test.

The auditory temporal resolving power of young children was measured using an adaptive forced choice psycho-physical paradigm that was disguised as a video game. (PCB)

Frequency difference limens (DLFs) for pure tones were obtained over a wide range of frequencies and levels from 7 normal-hearing subjects and 16 ears of 12 listeners with sensorineural hearing losses. Results indicated that it is reasonable to use data from normal listeners' DLFs to evaluate DLFs from hearing-impaired listeners. (Author/JDD)

Hearing sensitivity was examined prospectively in 114 young children as a function of otitis media with effusion (OEM)status in years 1, 2, and 3. Results indicated that children classified as bilaterally OME positive in years 1, 2, and 3 had significantly poorer hearing than children classified as bilaterally OME free at these periods. (Contains…

A pilot project evaluated the use of a microcomputer database system to maintain hearing screening, evaluation, and followup records in a school for physically, emotionally, or educationally handicapped children (6 months-18 years). Using a universal database management system for a microcomputer, a program was designed which would allow for easy…

Black (n=63) and White (n=74) infants, aged 6-13 months, were screened by tympanometry for middle-ear dysfunction. More White infants than Black failed initial screening. Retest of initial failures after a 6-week interval showed an overall reduction in failure rates, but the significant racial effect was still obtained. (Author/JDD)

In a study of 15 individuals (ages 15-21) with Down Syndrome, auditory brainstem response (ABR) detection levels were elevated, response amplitude reduced, and latency-intensity functions were significantly steeper than for a matched control group. Findings were associated with an impairment in hearing sensitivity at 8000 Hz for the experimental…

Studies on visual, musical, and speech perception abilities were used to construct auditory ability tests. Correlation and factorial analyses indicated separate capacities for auditory verbal comprehension, auditory immediate memory, temporal tracking, auditory cognition of relationships, discrimination among sound patterns, speech perception…

The study investigates differences in the auditory discrimination ability of 24 elementary school age reading achievers and underachievers, as measured by standard audiometric tests and nonconventional auditory tests. The findings show that reading underachievers scored significantly poorer than reading achievers on some of the nonconventional…
