Background: Before advanced noise-management features can be recommended for use in children with hearing loss, evidence regarding their ability to use these features to optimize speech perception is necessary.
Purpose: The purpose of this study was to examine the relation between children's preference for, and performance with, four combinations of noise-management features in noisy listening environments.
Research Design: Children with hearing loss were asked to repeat short sentences presented in steady-state noise or in multitalker babble while wearing ear-level hearing aids. The aids were programmed with four memories having an orthogonal arrangement of two noise-management features. The children were also asked to indicate the hearing aid memory that they preferred in each of the listening conditions both initially and after a short period of use.
Study Sample: Fifteen children between the ages of 8 and 12 yr with moderate hearing losses, bilaterally.
Results: The children's preference for noise management aligned well with their performance for at least three of the four listening conditions. The configuration of noise-management features had little effect on speech perception with the exception of reduced performance for speech originating from behind the child while in a directional hearing aid setting. Additionally, the children's preference appeared to be governed by listening comfort, even under conditions for which a benefit was not expected such as the use of digital noise reduction in the multitalker babble conditions.
Conclusions: The results serve as evidence in support of the use of noise-management features in grade-school children as young as 8 yr of age.
