Introduction & Theoretical Background
Tinnitus is thought to be associated with changes in the way in which the brain processes information. Normally a filter operates to 'tune out' unnecessary noises - including physiological noises - allowing for habituation to certain noises. In tinnitus this mechanism seems to fail - leading to awareness of physioloigcal noises. Awareness and particular attributions can lead to emotional reactions, which can exacerbate perception of the noise. What Causes Tinnitus? is a description of this process. This information sheet forms part of a cognitive-behavioral understanding of tinnitus.
