A new challenge for pediatric audiology: Public Law 99-457.

When fully implemented, the most recent amendments to the Education of the Handicapped Act will have a substantial impact on expanding services to infants and toddlers with handicapping conditions and their families. Audiologists in many settings will be called upon to participate in the implementation of this new mandate. It is imperative that audiologists be well informed about Public Law 99-457 as state and local policies are being developed and implemented. This article reviews the new law with emphasis on its implications for young hearing-impaired children, their families, and the audiologists who serve them.

Normal ABR's in children classified as learning disabled.

Some preliminary studies on children identified as having "minimal brain dysfunction" have suggested that auditory brainstem (ABR) latency measures may be useful in facilitating early identification of children with learning disabilities. However, the present investigation on 20 boys aged 9-14 yrs classified as learning disabled according to typical psychoeducational criteria used in the United States showed that no ABR latency measure to repetitive click stimuli could differentiate this group from age-matched normal controls. Furthermore, psychoeducational Battery was not related to ABR latency in these children.

Binaural fusion, masking level differences, and auditory brain stem responses in children with language-learning disabilities.

This report examines binaural fusion for dichotically and diotically presented pass-bands of filtered speech in a group of 18 normal children and 18 children with language-learning disabilities. Binaural masking level differences for tonal stimuli and auditory brain stem responses for click stimuli are also reported. Results indicate lower overall scores for the experimental group on the diotic as well as dichotic conditions for the binaural fusion tasks, although both groups scored relatively higher in the diotic condition. Masking level differences and auditory brain stem responses were not significantly different for the two groups. These findings suggest the potential usefulness of binaural fusion measures in the assessment of auditory processing abilities in children, although certain cautions regarding their application and interpretation must be exercised.

Pure-tone and acoustic immittance screening of preschool-aged children: an examination of referral criteria.

Seventy-five 3- and 4-yr-old children participated in a hearing screening program that included both pure-tone and acoustic immittance measures. ASHA's guidelines for acoustic immittance screening were modified to include a rescreening of all children failing the immittance test. Results were then compared to those projected from the existing ASHA criteria and two other screening protocols. Our findings revealed a higher incidence of otologic abnormalities in preschoolers compared to school-aged children and a higher incidence of false positives, even when immittance rescreening was provided. Pure-tone audiometry was ineffective as a means of identifying otologic abnormalities. A comparison of the immittance screening protocols indicated that the ASHA guidelines are likely to result in an excessive number of false-positive medical referrals. Recommendations are made for procedural modifications aimed at improving the efficiency of this procedure.
