Importance of Sufficient Output Saturation Sound Pressure Level at 90 dB on Hearing Aids
JR is a 25-year-old male with a flat 60 dB HL sensorineural hearing loss. He has been wearing behind-the-ear (BTE) hearing aids with skeleton, nonvented earmolds since 3 years of age. His first hearing aids were bilateral Widex ES8 BTEs (Widex USA, Inc., Hauppauge, NY). He was fitted with bilateral Diva 9 BTE hearing aids (Widex) approximately 10 years ago. JR reported satisfaction with the Diva hearing aids, but because he was starting a new job as an engineer he thought it was prudent to upgrade the Diva 9 aids to more current technology.
After a conventional audiological examination confirmed the magnitude of hearing loss and medical clearance was obtained, the audiologist recommended bilateral digital wireless Widex CLEAR 440–9 BTEs for JR to be consistent with what he had been wearing. JR felt, however, that cosmetics were important and decided instead to purchase bilateral Widex CLEAR 440 C4-Passion (C4-Passion) receiver-in-the-canal (RIC) hearing aids. This is a subminiature RIC-style hearing aid with a thin wire connecting the hearing aid case to the receiver, which is placed inside an instant-fit dome. No vent was used on the dome.
