Background: Children with hearing loss often exhibit reduced psychosocial status compared to children with normal hearing. It is reasonable to assume that psychosocial function may also be affected in children diagnosed with auditory processing disorder (APD). However, there are no published studies specifically addressing the psychosocial health of children with APD.

Baseline measures of the children with APD, prior to FM use, documented significantly lower speech-perception scores, evidence of decreased academic performance, and psychosocial problems in comparison to an age- and gender-matched control group. Repeated measures during the school year demonstrated speech-perception improvement in noisy classroom environments as well as significant academic and psychosocial benefits.

The purpose of this investigation was to compare two types of technologies that have been shown to improve the speech-perception performance of individuals with SNHL: directional microphones and frequency modulation (FM) systems. Forty-six adult subjects with slight to severe SNHL served as subjects.

Previous investigations have demonstrated that the microphone design of the FM transmitter can have a significant impact on this improved speech perception. The purpose of this investigation was to compare 3 types of FM transmitter microphone designs: (a) wide angle (omnidirectional microphone), which amplifies sounds coming from all directions around the microphone equally; (b) zoom (1 directional microphone), which provides less amplification to signals coming from the rear, and (c) superzoom (2 directional microphones), which provides less amplification to signals originating from the rear and the sides.

An additional objective was to compare performance on auditory tasks to results from standardized tests of reading in an attempt to generate a clinically useful profile of developmental dyslexics with comorbid APD.
Design: A group of eleven persons with developmental dyslexia and 14 age- and intelligence-matched controls participated in the study.
This investigation examined the relations among hearing loss, handicap perception, and functional health status of 152 African American and Caucasian American seniors ranging in age from 60 to 89 years. Subjective measures were obtained from self-report scores on the Hearing Handicap Inventory for the Elderly (HHIE), the Medical Outcomes Study 36-Item Short Form Health Survey (SF-36), and demographic profiles. Results indicated the following: (1) both subject groups exhibited nearly identical degrees of sensorineural hearing loss consistent with presbyacusis; (2) African American seniors reported significantly lower levels of completed education than did Caucasian American seniors; (3) differences between groups in self-report scores of hearing handicap (HHIE) were not statistically significant; (4) differences across groups in self-report scores of functional health status (SF-36) were not statistically significant; and (5) increasing levels of hearing loss produced significantly higher HHIE scores and significantly lower SF-36 scores in each group.

Some of these children have hearing loss; others have essentially normal hearing but are at risk for accurate speech perception. Hearing aid fitting protocols and technology can be effective for children with hearing loss, but the aids must be selected and adjusted for classroom environments.

Past investigations demonstrate that the acoustical environment of a classroom is a critical factor in the academic, psychoeducational, and psychosocial achievement of children with normal hearing and with hearing impairment. This article examines several acoustical variables, such as noise, reverberation, and speaker-listener distance, which can deleteriously affect speech perception in classrooms. Moreover, the discussion examines the effects of these variables on the speech perception abilities of both children with normal hearing and children with hearing loss.
