Ninetieth percentile cutoffs for acoustic reflex thresholds (ART) were determined for a sample of 1,374 adult subjects with normal hearing and sensorineural loss of cochlear origin. It was found that 12.2 percent had one ear ART elevated above the ninetieth percentile, but only 5.6 percent had more than one elevated ART. (DB)

The contribution that attentional factors, listener biases, and other nonsensory variables make to stimulus dominance in a dichotic listening task was assessed by comparison of scores obtained in a conventional two-ear monitoring task and a yes/no target-monitoring task. Results suggested that nonsensory factors had little influence in determining…

Assessment of auditory abilities is important in the diagnosis and treatment of children with autism. The aim was to evaluate hearing objectively by using transient evoked otoacoustic emission (TEOAE) and auditory brainstem response (ABR). Tests were performed on 30 children with autism and 15 typically developing children, following otomicroscopy…

The limitations of noisemakers and speech in detecting marked high-frequency hearing impairment in young children are illustrated by special analysis. (Author)

Text and graphs describe the Dynamic Range Configuration audiogram developed at the Central Institute for the Deaf in St. Louis, Missouri. The audiogram displays the portion of the average speech spectrum audible to the child, with and without amplification, and can be effective in counseling parents and planning appropriate amplification.…

A simple procedure for measuring changes in the acoustic impedance of the ear is described. The technique has several applications, including simulation using a standard coupler of changes in real ear impedance produced by the acoustic reflex, and calibration of response time of an otoadmittance meter. (Author/DB)

Purpose: Some researchers have assessed ear-specific performance of auditory processing ability using speech recognition tasks with normative data based on diotic administration. The present study investigated whether monotic and diotic administrations yield similar results using the Selective Auditory Attention Test. Method: Seventy-two typically…

According to the Royal National Institute for the Deaf, between eight and nine million people suffer from some form of deafness or loss of hearing. Modern technology, however, together with the work of audiologists such as Karen Shepherd, enables many adults and children to recover near-normal levels of hearing, even when they have suffered some…

Infant hearing screening is emerging rapidly as a silent global revolution for the early detection of children with congenital or early onset hearing loss to ensure timely enrollment in family-oriented intervention programs for the development of spoken language. This article examines the overriding and interrelated scientific, ethical and…

The article profiles five cases of children (8-17 years old) with learning disabilities and auditory processing problems. Possible correlations between the presumed etiology and the unique audiological pattern on the central test battery are analyzed. (Author/CL)

The study examined the test-retest reliability in unaided and aided sound-field thresholds and the functional gain values derived from these measurements in 24 hearing-impaired adults. Test-retest standard deviations were slightly larger for functional gain than for unaided thresholds. (Author/DB)

This study investigated comodulation masking release (CMR) in 42 children (ages 5 to 10) with a history of otitis media with effusion (OME) and 19 control children with no history of ear disease. Results indicated that monotic CMRs were reduced in children with hearing loss due to OME and these CMRs remained abnormally small for several months.…

This study, with 26 normal hearing subjects, investigated the development of temporal resolution as a function of frequency region, using a modified masking period pattern model. Results indicated that temporal resolution improves with age, with improvement for low frequencies continuing beyond age 10 but high frequency improvement approaching…

Infants (n=34) were tested on a speech-sound discrimination-in-noise task using the visual reinforcement of infant speech discrimination procedure. An adult control group was also tested. The infant-adult difference in discrimination threshold in noise was 6.9 dB. Advantages of this adaptive threshold procedure and possible applications are noted.…
