Subjective, primary tinnitus is the most common type. Tinnitus perception is neurologically generated in the auditory cortex, an area of the brain concerned with the processing of signals originating in the cochlea – the hearing nerve.
Usually primary tinnitus can be linked to hearing loss. It’s true to say that the characteristics of the perception audible to the individual often reflect the nature of the hearing loss. For example, high-frequency hearing loss often results in a high-pitched tinnitus perception. Although, hearing loss is a contributing factor for the initiation and continuation of tinnitus, other physiological and psychological factors are involved.
A common trigger is often underlying stress or anxiety. In fact, the emotional response of an individual to tinnitus is often critical in determining the severity of the symptoms and the resulting impact on one’s quality of life.
