Cochlear Dead Regions
YT has a long-standing bilateral asymmetrical (right poorer than left at 1000 to 2000 Hz) moderate sensorineural hearing loss sloping to severe/profound sensorineural hearing loss in the high frequencies. She has worn bilateral hearing aids for 5 years but reports that she does not receive the benefit she had hoped for. She reports there is a lack of clarity, particularly when listening in noise. Furthermore, she describes the sound of the aids as tinny and harsh, especially when listening to sounds at high input levels.
YT works as a volunteer for a local charity helping the elderly manage their hearing aids. She has become aware that the benefit she receives from her hearing aids appears to be lower compared to that of the people she encounters. She is concerned that her hearing aids are not programmed correctly. She schedules frequent appointments (nine appointments in the last 2 years) for her hearing aids to be reprogrammed, hoping to achieve better performance.
