Background: There are many counseling and sound therapy approaches to treat tinnitus. Counseling approaches range from providing information using directive or collaborative approaches. Sound therapies include strategies that use background sounds to totally or partially mask tinnitus to reduce the prominence of or decrease the loudness or annoyance of the tinnitus.

Method: A website was created for people with tinnitus to complete a variety of questions.
Results: The 1,788 subjects who responded to questionnaires came from 53 different countries; 413 (23.
Background: Several tinnitus sufferers suggest that manganese has been helpful with their tinnitus.
Purpose: We tested this in a controlled experiment where participants were committed to taking manganese and Lipoflavonoid Plus(®) to treat their tinnitus.
Research Design: Randomized controlled trial.
Purpose: Our objective was to identify activities that influence tinnitus and to determine if conditional probabilities exist among such variables.
Method: Two hundred fifty-eight patients were asked the following two questions: "When you have your tinnitus, which of the following makes it worse?" and "Which of the following reduces your tinnitus?"
Results: Things that made tinnitus better included noise (31%) and relaxation (15%). Things that made tinnitus worse included being in a quiet place (48%), stress (36%), being in a noisy place (32%), and lack of sleep (27%).
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 postlingual subjects participated in this study. Average age at implant was 63 years.
Purpose: To create a questionnaire focused on the primary activities impaired by tinnitus and therefore more sensitive to treatments.
Method: Questions were developed on (a) emotions, (b) hearing, (c) sleep, and (d) concentration. A 20-item questionnaire was administered to 158 patients.
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.
Design: A linear mixed-model framework was used to determine the effect of age at implantation on speech perception, language, and reading abilities in 83 children with prelingual hearing loss who received cochlear implants by the age of 4 years.
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.

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 implants bypass the membranous labyrinth but rely on the spiral ganglion for functionality, we hypothesize that cochlear implant (CI) performance is dictated in part by the anatomic location of the cochlear pathology that underlies the hearing loss.

Method: Nine subjects were tested on speech perception in quiet, and 13 subjects were tested on speech perception and localization in noise using an array of 8 loudspeakers. All subjects were tested with unilateral CI prior to bilateral implantation and then again with bilateral CI after at least 3 months of bilateral experience.
Objectives: Habituation to tinnitus cannot occur with total masking, an argument made by proponents of "tinnitus retraining therapy." We also compared the effectiveness of retraining therapy with mixing-point masking, total masking, and with counseling alone.
Design: Forty-eight tinnitus patients were randomly assigned to one of three groups: counseling, counseling plus bilateral noise generators set to completely mask the tinnitus, or counseling plus bilateral noise generators with a focus on the mixing point (partial masking just below total masking).
Background: Maximum performance and long-term stability of bilateral cochlear implants has become an important topic because there has been increasing numbers of recipients of bilateral cochlear implants.
Purpose: To determine the performance over time (up to 6yr) of subjects with simultaneous bilateral cochlear implants (CI+CI) on word recognition and localization.
Research Design: Over-time investigation of word recognition in quiet (CNC) and sound localization in quiet (Everyday Sounds Localization Test).
Purpose: To determine (a) changes in the Tinnitus Handicap Questionnaire (THQ) for patients using cochlear implants, (b) differences between patients who receive total or partial relief, and (c) identifiable characteristics of those who report tinnitus after implantation.
Method: Pre- and postoperatively, 244 adults were administered the THQ when they reported tinnitus.
Results: Of the 153 patients who had tinnitus preoperatively, 94 (61%) patients reported total suppression and 59 (39%) reported a partial reduction.
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 significantly better than the CI-only subjects.
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.

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; pertaining to the perception of male, female, and children's voices; music in quiet; source localization; understanding speech in quiet; and understanding speech in noise.

We review strategies for subgrouping based on etiology, subjective reports, the audiogram, psychoacoustics, imaging, and cluster analysis.
Method: Preliminary results of a 2-step cluster analysis based on 246 participants from whom we had 26 categorical and 25 continuous variables were determined.
