Children with hearing loss are at a disadvantage for language learning because they are unable to hear many of the important, yet subtle, cues necessary for speech and language development. Even when using current digital hearing aids, children with hearing loss are often unable to hear speech cues in the high frequency range. Frequency lowering is a processing strategy in which the hearing aid transfers higher frequency inputs to a lower frequency range that can be adequately amplified by the device. Two types of frequency lowering algorithms are currently available for use in children and have been shown to be successful for improving high frequency audibility in children with high frequency hearing loss. The purpose of this capstone is to describe the use of frequency lowering techniques to improve high frequency audibility for children with hearing loss. Specifically, this capstone will focus on the different types of frequency lowering and recent research outcomes, fitting considerations in the pediatric population, and considerations in acclimatization and auditory training with frequency lowering technology. In addition, a case example is provided to demonstrate candidacy, fitting, and verification concepts in a real world situation.
