Fifty-eight children (from 4 to 19 years of age) with bilateral, symmetrical, sensorineural hearing loss, who had used a hearing aid in only one ear for 1 to 19 years were investigated to study the influence of hearing-aid upon the residual hearing between the used and no used ears. The results were as follows, 1) The average hearing level for the used ear at seven frequencies was 49. 5 dB of p...
BACKGROUND Some patients have to stop using their air-conduction hearing aid(s) because it causes or exacerbates chronic otitis. Then, a solution is the use of a bone-conduction hearing aid such as the percutaneous bone-anchored hearing aid (BAHA). OBJECTIVE To compare patients' performance with their previous air-conduction hearing aid(s) and their BAHA using audiometric tests and a question...
OBJECTIVE Determine the extent to which pre-fitting acceptable noise level (ANL), with or without other predictors such as hearing-aid experience, can predict real-world hearing-aid outcomes at three and 12 months post-fitting. DESIGN ANLs were measured before hearing-aid fitting. Post-fitting outcome was assessed using the international outcome inventory for hearing aids (IOI-HA) and a heari...
BACKGROUND Hearing impairment is the most common body system disability in veterans. In 2008, nearly 520,000 veterans had a disability for hearing loss through the Department of Veterans Affairs (VA). Changes in eligibility for hearing aid services, along with the aging population, contributed to a greater than 300% increase in the number of hearing aids dispensed from 1996 to 2006. In 2006, th...
Currently published hearing aid fitting protocols recommend speech-in-noise testing and loudness measures, but it remains unclear how these measures affect hearing aid benefit and user satisfaction. This study compared two protocols in their effects on benefit and satisfaction. Protocol A included an electroacoustic analysis, real-ear measures, and hearing aid adjustments based on users' commen...
Our purpose is to apply a basilar hardware membrane model (BMM) to hearing-aid systems to solve some of the problem in existing hearing-aid systems. In this study, we construct a BMM using Simulink. Also, we experiment on the response characteristics of our BMM implementation to C6713DSK, using real sounds and hearing-loss sounds, which imitate a hearing-impaired person’s hearing ability. It is...
The present investigation further analysed results of a previously reported survey with a large sample of hearing aid owners (Bertoli et al, 2009) to determine the individual and technological factors related to hearing aid outcome. In particular the associations of hearing loss, level of signal processing, and fitting type (bilateral versus unilateral fitting) with hearing aid use, satisfactio...
