Abstract
The aim of this paper is to provide information about the neurophysiologic model of
tinnitus and Tinnitus Retraining Therapy (TRT). With this overview of the model and
therapy, professionals may discern with this basic foundation of knowledge whether
they wish to pursue learning and subsequently implement TRT in their practice. This
paper provides an overview only and is insufficient for the implementation of TRT.
