Previous studies report that enhanced power in the delta range (1.5-4Hz) and reduced power in the alpha frequency band (8-12Hz) were most pronounced in the temporal regions. These studies referred to the 8-12Hz activity as tau activity, and they created a new neurofeedback protocol to treat tinnitus using a temporally generated tau rhythm (8-12Hz) and slow waves in the delta range (3-4Hz) for feedback. This study aims to repeat this protocol and to evaluate its effect on tinnitus.
Fifteen normal-hearing patients with tinnitus were treated with the neurofeedback protocol. The Tinnitus Handicap Inventory and Visual Analogue Scales were administered before and after treatment and at 1, 3 and 6 months post-treatment.
After therapy, all questionnaires scores were significant improved, and the improvements persisted throughout the followup period. Moreover, an increasing trend in the tau/delta ratio was observed; specifically, the trend was more stable respect of the pre-recording measure. However, only in some subjects may the signal alone be enough to develop the correct behaviors.
Further studies are necessary to characterize the tinnitus subjects who recovered from and adapted to this psychophysical condition and, therefore, responded to neurofeedback therapy.

One such therapy is the Neurofeedback technique which has already been proven effective in the treatment of tinnitus (Crocetti et al. 2011; Dohrmann et al. 2007; Hartmann et al. 2013). An example study by Dohrmann et al. (2007) demonstrated that the delta/alpha ratio Neurofeedback protocol could bring about a significant improvement in subjective perception of tinnitus. "

ABSTRACT: This study is the first to demonstrate outcomes of slow cortical potential (SCP) Neurofeedback training in chronic tinnitus. A 50-year old male patient with tinnitus participated in three SCP training blocks, separated with 1-month breaks. After the training the patient reported decreased tinnitus loudness and pitch, as well as improved quality of daily life. A quantitative electroencephalography analysis revealed close to normal changes of resting state bioelectrical activity in cortical areas considered to be involved in tinnitus generation. The present case study indicates that SCP Neurofeedback training can be considered a promising method for tinnitus treatment.

- "identification and management of conditions that cause secondary tinnitus, counseling, fitting of hearing aid, and/ or sound generator).  Several neuromodulation techniques, such as Transcranial Magnetic Stimulation (TMS)  , transcranical Direct Current Stimulation (tDCS)  and neurofeedback , were reported to decrease neural activity associated with tinnitus.  Although the neuromodulation techniques showed some promising effects, the main effect is still small and not always repeatable. "

ABSTRACT: Purpose of review. Subjective tinnitus can be caused by a variety of causes, and therefore tinnitus patients constitute a very heterogeneous population difficult to manage. In this article, we reviewed the current literature to present our conceptual model of the conscious auditory percept and tinnitus based on experimental research in order to explain the clinical approach to the individual tinnitus patient.
Recent findings. Fundamental research has provided evidence to support the neurophysiological model of tinnitus developed by Jastreboff. By manipulating the limbic, autonomic and auditory systems, tinnitus retraining therapy (TRT) aims to reduce the response to the abnormal stimulus. Evidence has confirmed the effectiveness of TRT and cognitive behavioral therapy (CBT) in reducing the negative impact of subjective tinnitus on the patients’ quality of life.
Summary. Every patient with subjective tinnitus has its unique ‘tinnitus profile’ which provides a guide to the necessary combination of therapeutic actions. Evidence suggests the multidisciplinary approach combining etiological therapy as well as TRT, and CBT in specialized clinics is not only effective in reducing the patient’s quality of life but also cost-effective from a healthcare and societal point of view.

ABSTRACT: Background: Because chronic tinnitus is a condition that negatively impacts the quality of life of millions of people worldwide, a safe and effective treatment for tinnitus has been sought for millennia. However, effective treatments for tinnitus are greatly outnumbered by ineffective strategies, medications, devices, and surgeries that continue to be developed and promoted for the condition. Purpose: This article describes and critiques experimental, controversial, and potential treatments for chronic tinnitus. The purpose of this review is to provide information that should help patients and clinicians to select tinnitus treatment and management strategies most likely to be effective for each set of symptoms and circumstances. Research Design: PubMed and MEDLINE databases (National Center for Biotechnology Information, U.S. National Library of Medicine) were searched for the term tinnitus in articles published from 1940 to 2012. Other historical documents and publications were also reviewed as needed for particular topics. Study Sample: Studies included in this review were selected to represent a sampling of treatment methodologies that have been used for tinnitus. Data Collection and Analysis: Due to the heterogeneity of the studies reviewed, it was not appropriate to perform a meta-analysis. A selective review of the literature was conducted to summarize and critique published research results. Results: Most invasive treatments for tinnitus should be avoided because (1) at best, there is scant evidence that any of these treatments is effective, and (2) the risk to patients for most invasive procedures is much greater than the risk posed by the tinnitus perception. Effective and noninvasive treatments for tinnitus include acoustic therapy (which includes hearing aids and other types of environmental sound enrichment); cognitive-behavioral therapy; psychological counseling; hypnosis; biofeedback; and relaxation training. Over-the-counter or prescription medications may be used as needed to facilitate sleep and to reduce anxiety, depression, or obsessive-compulsiveness. Conclusions: Patients and clinicians should be especially cautious when considering invasive (and potentially harmful) treatments for tinnitus, which is a non-life-threatening symptom. Unless well-designed clinical trials verify that a tinnitus therapy demonstrates effectiveness above and beyond the placebo effect, consumers should be wary of medications, devices, or procedures promoted as a "cure." Although a true cure for tinnitus has not yet been found, effective and noninvasive tinnitus management strategies are available now. If progress is made to medically (or genetically) treat sensorineural hearing loss in humans, this breakthrough should also help to simultaneously reduce the perception of tinnitus for many patients.
