摘要

Tinnitus, the perception of sound without an external stimulus, is a prevalent and often distressing auditory condition. Despite its frequency, its pathophysiology remains complex. This study aims to explore the audiometric profiles of tinnitus patients and investigate the relationship between tinnitus pitch and loudness matching and the efficacy of masking. This cross-sectional study,conducted in Department of ENT, at a tertiary care hospital attached to a medical college in North India, evaluated 93 patients aged over 15 years with unilateral or bilateral tinnitus and intact tympanic membranes. A comprehensive clinical and audiological assessment was carried out, including pure tone audiometry PTA, SISI, ABLB, TDT, and impedance audiometry. Tinnitus pitch and loudness were matched using narrow-band stimuli, and masking trials were performed to assess the masking threshold. Tinnitus was most common in the 15–25-year age group (36.6%) and more prevalent in males (64.5%). Eustachian tube dysfunction and idiopathic sudden sensorineural hearing loss were leading etiologies. Tinnitus frequency most frequently matched in the 0–2000 Hz range, and loudness matched predominantly between 26–35 dB HL. Masking was also most effective within the 0–2000 Hz range and at loudness levels between 35–50 dB HL. Mild sensorineural hearing loss was the most common audiometric finding. Most tinnitus cases exhibited low-frequency matching and masking patterns, aligning with common sound therapy approaches. Mild sensorineural hearing loss often accompanies tinnitus, underscoring the need for early audiometric evaluation. Understanding matching and masking characteristics can inform targeted interventions, including sound therapy and hearing devices tailored to individual tinnitus profiles.
