Tinnitus is characterized by the perception of sound without an existing external stimulus. The presence of tinnitus might be intolerable for many and can be sufficiently troublesome in hearing, sleep, thought processing, and other functional abilities, all of which can negatively impact the quality of life. Individuals with tinnitus may have decreased cognitive efficiency because tinnitus can adversely affect the other tasks being performed. The present study was taken up to evaluate auditory working memory using digit span tasks in adults with tinnitus.
The tasks administered included forward, backward, ascending, and descending digit span. Tinnitus Handicap Inventory questionnaire was administered on all the individuals with tinnitus, and also, it was attempted to correlate the scores of auditory working memory with that of tinnitus handicap inventory.
The results indicated poorer scores for backward, ascending and descending digit span task and no significant difference for the forward digit span task. There was no correlation between auditory working memory tasks and overall tinnitus handicap scores along with its sub-scales.
It was concluded that tinnitus disrupts the functioning of auditory working memory and is governed by the annoyance caused by tinnitus.
