摘要:

A modified mass newborn hearing screening program was piloted using a combination of a simplified high-risk register and a newly developed automated screening device. The Auditory Response Cradle. The program was designed to handle a total of 4000 babies per year. All children participating received both the high-risk register review and the automated screening test. The Auditory Response Cradle used a bin-aurally presented high-pass noise through a closed acoustic system at an intrameatally monitored level of 85 dB SPL (re 20 μPa)± 3 dB. Three independent motor and two respiratory response channels were monitored by the controlling microprocessor unit during a 5-sec prestimulus interval, and a 5-sec stimulus interval. Typical time for a complete test ranged from 5 to 10 min. The results of the present work indicate a false positive rate at or below 1.5%. The described program appears to be a cost-effective means of providing a mass neonatal hearing screening.

摘要:

Variations in auditory brain stem response latency, threshold, and amplitude ratio were related to stimulus, recording, subject, and pathologic factors in normal and high-risk infants.

摘要:

Definitive diagnosis of hearing impairment may represent the first objective evidence of physiologic dysfunction in an infant or child with undetected associated abnormalities. The audiologist and otologist should be able to recognize many genetic abnormalities and dysmorphic syndromes. Six case summaries illustrate the importance of total evaluation of the hearing-impaired child. As an aid to eliciting important information, an associated system abnormalities questionnaire is provided.

摘要:

Results of a 9-mo longitudinal study designed to evaluate the efficacy of a vibrotactile aid, the SRA-l o, with four profoundly deaf preschool children are reported. During the study the subjects were enrolled in 30-min triweekly language therapy sessions, and changes in communication skills in connected discourse (vocalization only, sign language only, and vocalization PIUS sign language) were measured using a computer-based observation system. Changes in structural and semantic aspects of language were also measured. The four subjects were evaluated during one 16-week phase in which the aid was used (aid-on condition) and another 8 weeks in duration in which the aid was not used (aid-off condition). Communication skills improved in the aid-on condition and decreased in the aid-off condition. The changes were found to be significant for the communication involving the vocalization plus sign language (Total Communication) measure, indicating that the vibrotactile stimulation was Positively associated with the communicative act.

摘要:

In recent years, the House single-electrode cochlear implant has proven to be a clinically feasible prosthesis for profoundly deaf adults. Based on these findings, the decision was made to begin implanting those children who could not benefit from hearing aids. As of August 1982, 23 profoundly deaf children (ranging in age from 3.4 to 17.5 yrs) have received the cochlear implant. The majority were deafened by meningitis. Results to date indicate that children demonstrate sound field thresholds and receive timing/intensity information comparable to that of adult implant patients. Results have been extremely encouraging, but only long-term experience will determine the ultimate benefit of the implant in children.

摘要:

This article describes an electrophysiological taxonomy of patients who are unwilling to continue wearing their hearing aids or are dissatisfied with the performance of the aid. Because the responses on which the taxonomy is based do not depend upon patient cooperation, they can be used in the pediatric population, where alternative procedures are less than optimal. Examples of how this electrophysiological taxonomy relates to patient management decisions are also provided.

摘要:

Normal children between 3 and 6 yrs old generated word and sentence messages for use in a pediatric speech intelligibility (PSI) test. Word materials did not differ as a function of chronological age (CA), vocabulary skills, or receptive language (RL) ability. Elicited sentence materials, however, did reflect differences in CA, vocabulary skills, and RL ability. To represent differences in the children's responses, two different types of test sentences, subsequently referred to as format I and format II sentences, were formed. Performance for format I and format II sentences was significantly different in normal children between 3 and 6 yrs old. Performance differences were related to CA and RL ability. However, performance for format I sentences in children with relatively low RL age and performance for format II sentences in children with relatively high RL age was equivalent. This observation yielded an algorithm that determines the sentence format as a function of a child's RL age in order to yield “language equivalent” norms for speech audiometry. In contrast to performance for PSI sentence materials, performance for PSI word materials was not influenced by differences in RL skill. Reliability coefficients for PSI word and sentence test-retest measures ranged from about 0.85 to 0.95 in normal-hearing and hearing-impaired children. Illustrative PSI results in children with confirmed central auditory disorders are presented.
