OBJECTIVE Compare speech performance in noise with matched bilateral cochlear implant (CICI) and unilateral cochlear implant (CI only) users. DESIGN Thirty CICI and 30 CI-only subjects were tested on a battery of speech perception tests in noise that use an eight-loudspeaker array. RESULTS On average, CICI subject's performance with speech in noise was(More)
BACKGROUND Up to 7% of patients with severe-to-profound deafness do not benefit from cochlear implantation. Given the high surgical implantation and clinical management cost of cochlear implantation (>$1 million lifetime cost), prospective identification of the worst performers would reduce unnecessary procedures and healthcare costs. Because cochlear(More)
We studied the relationship between tinnitus pitch and the audiogram in 195 patients. Patients with tone-like tinnitus reported a higher pitch (mean = 5385 Hz) compared to those with a noise-like quality (mean = 3266 Hz). Those with a flat audiogram were more likely to report: a noise-like tinnitus, a unilateral tinnitus, and have a pitch < 2000 Hz. The(More)
OBJECTIVES Few studies have examined the long-term effect of age at implantation on outcomes using multiple data points in children with cochlear implants. The goal of this study was to determine whether age at implantation has a significant, lasting impact on speech perception, language, and reading performance for children with prelingual hearing loss.

PURPOSE In this study, the authors sought to compare speech perception and localization in subjects who wear 1 cochlear implant (unilateral CI) or 1 cochlear implant and hearing aid (CI+HA) and then receive a second cochlear implant (bilateral CI), and to evaluate the importance of the duration between implant surgeries and duration of deafness.

OBJECTIVE Several reports suggest that zinc, which is involved in several neural transmissions systems throughout the auditory pathway, might help some tinnitus patients. However, previous studies used inadequate experimental designs. Therefore, we tested the effectiveness of zinc to reduce tinnitus. STUDY DESIGN Randomized, prospective double-blind(More)
OBJECTIVES Subjective questionnaires are informative in understanding the difficulties faced by patients with hearing loss. Our intent was to establish and validate a new questionnaire that encompasses situations emphasizing binaural hearing. The Spatial Hearing Questionnaire is a self-report assessment tool with eight subscales representing questions;(More)
PURPOSE The purpose of the present study is to evaluate the changes over time of the Spatial Hearing Questionnaire (SHQ; Tyler, Perreau, & Ji, 2009) and the Speech, Spatial and Qualities of Hearing Scale (SSQ; Gatehouse & Noble, 2004) in adults with simultaneous bilateral cochlear implants by collecting data for 2 years after implantation. METHOD Nineteen(More)
