Parent-Reported Ease of Listening in Preschool-Aged Children With Bilateral and Unilateral Hearing Loss

Objectives:Evidence from school-aged children suggests that the ease with which children listen varies with the presence of hearing loss and the acoustic environment despite the use of devices like hearing aids. However, little is known about the ease of listening in preschool-aged children with hearing loss-an age at which rapid learning occurs and increased listening difficulty or effort may diminish the required capacity to learn new skills. To this end, the objectives of the present study were to (i) assess parent-reported aided ease of listening as a function of hearing loss configuration (hearing loss in one versus both ears) and device configuration among children with hearing loss in one ear (unilateral hearing loss), and (ii) investigate factors that influence children's ease of listening.Design:Parents of 83 children with normal hearing, 54 aided children with bilateral hearing loss (hearing loss in both ears), and 139 children with unilateral hearing loss participated in the study. Of the 139 children with unilateral loss, 72 were unaided, 54 were aided with a device on the ear with hearing loss (direct aiding) and 13 were aided with a device that routed signals to the contralateral normal hearing ear (indirect aiding). Mean age of children was 40.2 months (1 SD = 2.5; range: 36 to 51). Parents completed the two subscales of the Parents' Evaluation of Aural/Oral Performance of Children+ (PEACH+) questionnaire, namely functional listening and ease of listening. Individual percent scores were computed for quiet and noisy situations. Linear mixed-effects models were used to assess the effect of hearing loss configuration and device configuration in children with unilateral hearing loss. Multiple regression was used to assess factors that influenced ease of listening. Factors included hearing thresholds, age at first device fit, consistency in device use, condition (quiet/noise), presence of developmental disabilities, and functional listening abilities.Results:Children with direct aiding for their hearing loss, either unilateral or bilateral, had similarly lower functional listening skills and ease of listening than their normal hearing peers. Unaided children with unilateral hearing loss had lower functional listening skills and ease of listening than their normal hearing peers in noise but not in quiet. All aided children with unilateral hearing loss, irrespective of direct or indirect aiding had lower functional listening skills and ease of listening relative to normal hearing children in both quiet and noise. Furthermore, relative to unaided children with unilateral hearing loss, those with indirect aiding had lower functional listening and ease of listening. Regression analyses revealed functional listening as a significant predictor of ease of listening in all children with hearing loss. In addition, worse degrees of hearing loss and presence of noise reduced ease of listening in unaided children with unilateral hearing loss.Conclusions:Bilateral hearing loss is associated with poorer-than-typical ease of listening in preschoolers even when aided. The impact of unilateral hearing loss on ease of listening is similar to that observed in children with bilateral hearing loss, despite good hearing in one ear and aiding. Given increased difficulties experienced by children with unilateral loss, with or without a device, additional strategies to facilitate communication abilities in noise should be a priority.
