title: The effect of tinnitus on some psychoacoustical abilities in individuals with normal hearing sensitivity.
abstract: BACKGROUND
  Tinnitus is the perception of a sound without an external source. It can affect auditory perception abilities in individuals with normal hearing sensitivity.
  
  
  OBJECTIVE
  The aim of the study was to determine the effect of tinnitus on psychoacoustic abilities in individuals with normal hearing sensitivity.
  
  
  METHODS
  The study was conducted on twenty subjects with tinnitus and twenty subjects without tinnitus. Tinnitus group was again divided into mild and moderate tinnitus based on the tinnitus handicap inventory.
  
  
  METHODS
  Differential limen of intensity, differential limen of frequency, gap detection test, modulation detection thresholds were done through the mlp toolbox in Matlab and speech in noise test was done with the help of Quick SIN in Kannada.
  
  
  RESULTS
  RESULTS of the study showed that the clinical group performed poorly in all the tests except for differential limen of intensity.
  
  
  CONCLUSIONS
  Tinnitus affects aspects of auditory perception like temporal resolution, speech perception in noise and frequency discrimination in individuals with normal hearing. This could be due to subtle changes in the central auditory system which is not reflected in the pure tone audiogram.
