简介：耳鸣是在没有外部来源的情况下对声音的感知。它可以影响听觉感知能力在个人与正常hearing sensitivity. Purpose：本研究的目的是确定耳鸣对心理声学能力的影响在个人与正常hearing sensitivity. MATERIALS AND METHODS：本研究进行了20例耳鸣和20例无耳鸣。耳鸣组根据耳鸣障碍量表分为轻、中度耳鸣，资料收集与分析：通过Matlab中的mlp工具箱进行强度差阈、频率差阈、间隙检测试验、调制检测阈值，并借助卡纳达语Quick SIN进行噪声中言语测试。结果的研究表明，临床组表现不佳，在所有的测试，除了差分limen的intensity.CONCLUSIONS：Tincraft影响方面的听觉，如时间分辨率，语音感知噪声和频率歧视的个人听力正常。这可能是由于中枢听觉系统的细微变化，而纯音听力图中没有反映出来。
INTRODUCTION: Tinnitus is the perception of a sound without an external source. It can affect auditory perception abilities in individuals with normal hearing sensitivity.PURPOSE: The aim of the study was to determine the effect of tinnitus on psychoacoustic abilities in individuals with normal hearing sensitivity.MATERIALS AND 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.DATA COLLECTION AND ANALYSIS: 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.
