I Hear Worse When I Wear Two Hearing Aids
An 82-year-old female experienced hearing aid user was referred by her audiologist for further diagnostic assessment 1 year after receiving her third pair of bilateral behind-the-ear (BTE) hearing aids JD had reported dissatisfaction with her hearing aids when listening in noisy environments.
JD is an 82-year-old woman returning to her audiologist 1 year after being fitted with bilateral BTE receiver-in-the-canal hearing aids with advanced signal processing technology and custom-made silicone earmolds. While JD remains a motivated hearing aid user, she reports increasingly limited benefit when wearing both of her hearing aids in noisy environments. The increasing stress and exhaustion from listening in noise is causing JD to withdraw from some social gatherings and events.
The audiologist had fitted JD’s hearing aids to real ear insertion gain (REIG) targets (with correction for binaural summation) set by the National Acoustic Laboratories non-linear version 2 formula (NAL-NL2: NAL's prescriptive procedure for fitting non-linear hearing aids, version 2) real ear insertion gain (REIG) targets (with correction for binaural summation) before guiding JD through a 12-week trial period. The trial included several visits by the audiologist to JD’s home in a retirement village where she worked with JD to manage the hearing aids and to communicate with family and friends during live social gatherings and events. The trial also included the use of a remote microphone coupled wirelessly to JD’s hearing aids via a streamer and telecoil neck loop.
