| Summary, etc | Background: Although guidelines for fitting hearing aids for children are well developed and have strong<br/>basis in evidence, specific protocols for fitting and verifying some technologies are not always available.<br/>One such technology is noise management in children’s hearing aids. Children are frequently in highlevel<br/>and/or noisy environments, and many options for noise management exist in modern hearing aids.<br/>Verification protocols are needed to define specific test signals and levels for use in clinical practice.<br/>Purpose: This work aims to (1) describe the variation in different brands of noise reduction processors in<br/>hearing aids and the verification of these processors and (2) determine whether these differences are<br/>perceived by 13 children who have hearing loss. Finally, we aimed to develop a verification protocol for<br/>use in pediatric clinical practice.<br/>Study Sample: A set of hearing aids was tested using both clinically available test systems and a reference<br/>system, so that the impacts of noise reduction signal processing in hearing aids could be characterized<br/>for speech in a variety of background noises. A second set of hearing aids was tested across a<br/>range of audiograms and across two clinical verification systems to characterize the variance in clinical<br/>verification measurements. Finally, a set of hearing aid recordings that varied by type of noise reduction<br/>was rated for sound quality by children with hearing loss.<br/>Results: Significant variation across makes and models of hearing aids was observed in both the speed of<br/>noise reduction activation and the magnitude of noise reduction. Reference measures indicate that noise-only<br/>testing may overestimate noise reduction magnitude compared to speech-in-noise testing. Variation across<br/>clinical test signalswas also observed, indicating that some test signalsmay bemore successful than others for<br/>characterization of hearing aid noise reduction. Children provided different sound quality ratings across hearing<br/>aids, and for one hearing aid rated the sound quality as higher with the noise reduction system activated.<br/>Conclusions: Implications for clinical verification systems may be that greater standardization and the use<br/>of speech-in-noise test signals may improve the quality and consistency of noise reduction verification |
