Equency ranges of 688?938 Hz or 1063?938 Hz. "Functional" acoustic hearing was defined by frequencies with thresholds better than 90 dB HL and provided with acoustic amplification. Subjects continued to use a hearing aid in the implant ear, with amplification provided up to the cutoff of functional hearing. The amplification characteristics applied to the low-frequencies were also based on targets

G to be functional and for the subject to be able to take advantage of the acoustic plus electric processing, it must be preserved better than 85?0 dB HL pure tone average (PTA) of 125?000 Hz. Furthermore, hearing loss was also classified by degree using the following definitions: ??????Mild: 26 to 40 dB HL, Moderate: 41 to 55 dB HL, Moderately severe: 56 to 70 dB HL, Severe: 71 to 90 dB HL, Profo

Ening level. Investigators instructed the subjects to maintain those settings for the remainder of the testing. Pre-Operative Candidacy and Baseline Procedures To document residual acoustic hearing, standard pure-tone air-conduction thresholds were measured in each ear at all frequencies from 125 ?8000 Hz using ER-3A insert earphones. Bone-conduction thresholds were also obtained between 250 Hz an

Eplications. Multiple regression models were used to examine the impact of age at implantation, duration of deafness, and post-operative LFPTA hearing thresholds impact speech perception scores. The post-operative scores were used as the outcome variable and the pre-operative scores were included as covariates in the model. In addition, a paired t-test was used to determine if scores significantly

S, etiology of the hearing loss was unknown (41/87 or 47.1 ), with many describing a family history of hearing loss (22/87 or 25.3 ). Etiologies of hearing loss in the remaining subjects included: history of noise exposure (15/87 or 17.2 ), autoimmune inner ear disease (2/87 or 2.3 ), measles (2/87 or 2.3 ), ototoxicity, neuritis, large vestibular aqueduct syndrome, Usher's Syndrome and endolympha

/87) of subjects experienced total hearing loss within one month following implantation. Total loss of hearing was recorded as 130 dB HL and this value was used in the averages described below. Evaluation of individual thresholds at initial activation showed that 94 of the subjects maintained functional hearing from 125 to 500 Hz. This would suggest that the surgical technique itself is sound in
