“…For example, more favorable signal-to-noise ratios are required for equivalent performance on speechperception tasks for individuals with mild to moderate hearing loss than for those who have normal hearing. 39 More recently, Crandell 44 examined the speech-recognition ability of school-aged children with minimal sensorineural hearing loss (thresholds between 15 and 30 dB bilaterally) and children with normal hearing. The speech-recognition scores of the children with hearing loss were significantly (3,6,9).…”

Since the early 1980s, audiologists have become increasingly aware of the potential effect of even mild degrees of hearing loss on the psychoeducational and psychosocial outcomes of children. This review describes some of the key research findings during the past several decades that have led us to our current thinking about unilateral and mild bilateral hearing loss in children. The first section addresses unilateral hearing loss. This is followed by a review of the literature on mild bilateral hearing loss. Specifically, the issues addressed include the significance of permanent mild degrees of hearing loss on children's psychoeducational and psychosocial development and the speech, language, and auditory characteristics of children with mild degrees of hearing loss. Finally, some recommendations regarding the direction of future research are offered. This review is followed by 2 articles summarizing the proceedings of a 2005 workshop convened by the Centers for Disease Control and Prevention (CDC), Early Hearing Detection and Intervention (EHDI) program, and the Marion Downs Hearing Center to address concerns about the underidentification of—and professionals' apparent lack of awareness of—permanent unilateral and minimal to mild hearing loss in children. 56,57

Variation in the Normal Hearing Threshold Predicts Childhood IQ, Linguistic, and Behavioral Outcomes

Childhood hearing level varies considerably within the range considered normal. Four classes of outcome were investigated for associations with hearing thresholds in this range: ability to identify speech in noise, neurocognitive ability, linguistic ability, and behavior. The research was conducted in a general population cohort of 711 children with mean hearing threshold of 15 dB HL or better. Some outcomes: speech in noise, intelligence, and certain linguistic abilities, were predicted in both boys and girls; effects were stronger in girls. In girls only, poorer hearing predicted worse behavior. These effects remained after statistical control for childhood socioeconomic status and otitis media. Variability in normal hearing, due to causes other than otitis media, is associated with the listening, language, and neurocognitive abilities of children, and the behavior of girls. We suggest that these effects may be present for three reasons, cochlear insults, neurodevelopmental factors, and psychological factors. We discuss how these may interact to produce the effects observed. T he conventional cut-off for normal-range hearing in children is 15 dB HL (1); which includes 97% (711/734) of the general population sample assessed here. This includes a wide range of actual hearing abilities, and how it relates to psychosocial consequences in humans is unclear (2). Hitherto, research has concentrated on effects in people with relatively large hearing losses, with little attention paid to the effects of variability within the normal range. We investigated four areas for which we hypothesized effects of hearing level in normally hearing children. Identification of signals in noise.A relation between puretone detection and identification of signals in noise has been demonstrated in minimally hearing-impaired children (3). Variation in normal hearing may be due to vulnerable structures involved in the cochlear active process (4). Children with poorer normal hearing may be less able to identify signals in noise due to slight deterioration in these systems.Neurocognitive ability. Assessment of hearing threshold measures performance on a psychoacoustical task in which general neurocognitive ability might play a part, so variation in threshold might be related to IQ. Furthermore, a body of research has related sensory processing, in terms of inspection time, with IQ (5-7). Thus, there may be a relation between hearing and IQ.Linguistic ability. Children with minimal hearing impairment perform less well on tests of educational performance, particularly in areas related to language (8). Furthermore, those with poor linguistic abilities perform less well on tests of acoustic frequency and temporal resolution (9,10). These findings are with stimuli requiring a high degree of processing (11), however, simple detectability may contribute to the effects shown.Behavior. Little research has investigated behavioral concomitants of variation in hearing in children. In deaf people, there may be effects with depression and interp...

“…Even so, it may be the case that listeners with childhood hearing losses experience more difficulty in noise but they simply have no reference to normal hearing and therefore have no reason to suspect that what they hear is any different than what others hear. We do know that children with even the mildest hearing losses are at risk for poor speech perception, academic performance, and social development in typical classroom noise (Davis et al, 1986;Crandell, 1993;Briscoe et al, 2001). We also know that the vocabulary development of children with hearing loss tends to be delayed relative to that of children with normal hearing by as much as 2 years, and that the delay persists throughout childhood and increases with increasing severity of hearing loss (Briscoe et al, 2001;Pittman et al, 2005).…”

Perceptual coherence in listeners having longstanding childhood hearing losses, listeners with adult-onset hearing losses, and listeners with normal hearing

Perceptual coherence, the process by which the individual elements of complex sounds are bound together, was examined in adult listeners with longstanding childhood hearing losses, listeners with adult-onset hearing losses, and listeners with normal hearing. It was hypothesized that perceptual coherence would vary in strength between the groups due to their substantial differences in hearing history. Bisyllabic words produced by three talkers as well as comodulated three-tone complexes served as stimuli. In the first task, the second formant of each word was isolated and presented for recognition. In the second task, an isolated formant was paired with an intact word and listeners indicated whether or not the isolated second formant was a component of the intact word. In the third task, the middle component of the three-tone complex was presented in the same manner. For the speech stimuli, results indicate normal perceptual coherence in the listeners with adult-onset hearing loss but significantly weaker coherence in the listeners with childhood hearing losses. No differences were observed across groups for the non-speech stimuli. These results suggest that perceptual coherence is relatively unaffected by hearing loss acquired during adulthood but appears to be impaired when hearing loss is present in early childhood.
