The evidence that cochlear implant listeners routinely experience stream segregation is limited and equivocal. Streaming in these listeners was explored using tone sequences matched to the center frequencies of the implant's 22 electrodes. Experiment 1 measured temporal discrimination for short (ABA triplet) and longer (12 AB cycles) sequences (tone/silence(More)
Over a five-year period, 34 patients have been referred to the Birmingham bone anchored hearing aid programme, paediatric section, of who 21 are now wearing the bone anchored hearing aid (BAHA) and four are awaiting surgery for fitting of the BAHA. Of the patients assessed, found to be suitable and who proceeded to surgery for the BAHA, 44 per cent had(More)
Adult users of unilateral Nucleus CI24 cochlear implants with the SPEAK processing strategy were randomised either to receive a second identical implant in the contralateral ear immediately, or to wait 12 months while they acted as controls for late-emerging benefits of the first implant. Twenty four subjects, twelve from each group, completed the study.(More)
The Vibrant Soundbridge, a semi-implantable hearing device for subjects with moderate to severe sensorineural hearing impairment was introduced commercially. First audiologic results are presented on 63 patients from 10 European implant centers. Hearing loss was at 0.5, 1, 2, and 4 kHz varying between 43 and 81 dB HL. The patients used the analogue audio(More)
We present the outcome of implantation in the first 100 adult patients treated under the Midland Cochlear Implant Programme. All patients were post-lingually deaf with profound or total hearing loss. Performance was tested in lip-reading, implant only and combined lip-reading and implant modes using BKB sentences, connected discourse tracking (CDT) and(More)
Previous claims that auditory stream segregation occurs in cochlear implant listeners are based on limited evidence. In experiment 1, eight listeners heard tones presented in a 30-s repeating ABA-sequence, with frequencies matching the centre frequencies of the implant's 22 electrodes. Tone A always stimulated electrode 11 (centre of the array); tone B(More)
Seventeen adult subjects participated in a multicentre trial to compare the performance between an NRT-based MAP and their behavioural MAP. The NRT-based MAP was made using a correction factor to predict T/C levels, calculated from the difference between the ECAP threshold ('T-NRT') and the measured T/C levels at electrode 10, as described by Brown et al.(More)
One hundred consecutive adult cochlear implant patients, numbered 101 to 200 in an ongoing series, were prospectively monitored and data collected using the same protocol as for the first 100 patients. The study period was 1999 to 2001. The total number of procedures was 122. Changes in practice following the first 100 implants included a standard surgical(More)
OBJECTIVES To assess the efficacy of the bone-anchored hearing aid (BAHA) in the rehabilitation of single-sided deafness (SSD). STUDY DESIGN Retrospective case-control series review. SETTING Tertiary referral unit. PATIENTS Fifty-eight consecutive patients that had a bone-anchored hearing aid for single-sided deafness completed outcome questionnaires,(More)
The Birmingham bone-anchored hearing aid (BAHA) programme has fitted more than 300 patients with unilateral bone-anchored hearing aids since 1988. Some of the patients who benefited well with unilateral aids and who had used bilateral conventional aids previously applied for bilateral amplification. To date, 15 patients have been fitted with bilateral(More)
