Does tinnitus and emotional distress influence central auditory processing? A comparison of acute and chronic tinnitus in normal-hearing individuals.

ABSTRACT:

Objective

Tinnitus is characterized by the perception of sound without an external source and can cause auditory difficulties even in individuals with normal hearing.

Design

This study compared the auditory afferent and efferent functions of normal-hearing patients with acute tinnitus, chronic tinnitus, and control group using gap detection test, the Mandarin Hearing in Noise Test (MHINT), and contralateral suppression of transient evoked otoacoustic emissions (TEOAEs).

Results

It reveals the neural and emotional dynamics as tinnitus progresses from acute to chronic stages. Patients with acute and chronic tinnitus exhibited reduced contralateral suppression of TEOAEs, elevated gap detection thresholds, and higher speech recognition thresholds in noisy environments, in
