Hearing Aid Noise Reduction in Pediatric Users (Oticon Study) — OtiS  

Hearing Loss, Sensorineural Clinical Trial

Official title:
Learning to Listen in Noise: A Double-blind Randomized Control Trial of a New Hearing Aid Noise Reduction System

Clinical Trial Summary

The purpose of this study is to evaluate the efficacy of OpenSound Navigator (OSN), a hearing aid speech-enhancement algorithm developed by Oticon, as treatment for pediatric hearing aid users. Using a double-blind experimental design, the investigators aim to compare two treatment groups of pediatric (ages 6-12) patients with symmetrical sensorineural hearing losses ranging from the mild to moderately-severe degree. One group will be fit with bilateral Oticon OPN™ behind-the-ear hearing aids set with an omni-directional microphone setting. The other group will be fit with the same hearing aid model with the OSN algorithm enabled. Participants from the groups will be age and audiogram-matched. The investigators will evaluate hearing aid benefit through word recognition in noise (behavioral testing) and everyday hearing/listening abilities (parental/legal guardian reported) at hearing aid fitting and 6-8 months post fitting.

Clinical Trial Description

OpenSound Navigator (OSN) is a speech enhancement hearing aid algorithm developed by Oticon that utilizes an adaptive directional microphone system with an automatic gain control noise reduction program. This hearing aid feature is intended for adult hearing aid users and its potential benefits of speech, vocabulary and listening development in pediatric users has not been investigated. Here the investigators aim to evaluate the efficacy of OSN programming in pediatric hearing aid users (6-12 years of age) diagnosed with a symmetrical sensorineural hearing loss in the mild to moderately-severe range. The investigators will use a double-blind randomized control methodology of two participant matched (based on age and audiometric configuration) groups. The first group will include pediatric patients fit with bilateral Oticon OPN™ behind-the-ear hearing aids with the standard Omni-directional microphone setting enabled. Group two will include pediatric patients fit with the same hearing aid model with the OSN feature enabled. Participants will undergo standard audiometric diagnostic testing and will be fit with the hearing aids by a licensed clinical audiologist. Participants are required to wear the hearing aids full time (at least 8 hours per day average) during the duration of the study. The evaluation measures will include speech recognition testing in controlled background noise and the Speech, Spatial and Qualities of Hearing Scale questionnaire (completed by parents/legal guardian). Testing will be performed within a week of the hearing aid fitting and 6-8 months post fitting. ;
