Assessment of Auditory Temporal Processing in Individuals with Subjective Tinnitus Using Gap Detection and Forward...

Area of Science:

• Audiology
• Neuroscience
• Psychology

Background:

• Subjective tinnitus is a common auditory disorder.
• Tinnitus can affect cognitive functions and daily life.

Purpose of the Study:

• To investigate auditory temporal processing and word discrimination in noise in individuals with subjective tinnitus.
• To assess the impact of tinnitus on daily activities and quality of life.

Main Methods:

• Fifty-five participants (27 with tinnitus, 28 controls) were assessed.
• Tests included Word-in-Noise (WIND), Gap Detection Test (GDT), Forward Masking Test (FMT), cognitive tests, and Tinnitus Handicap Inventory.

Main Results:

• Tinnitus group showed significantly poorer performance on GDT, FMT, and WIND compared to controls (p < 0.05).
• No significant difference in GDT/FMT was found between tinnitus subgroups with or without WIND problems, possibly due to small sample sizes.

Conclusions:

• Subjective tinnitus is associated with deficits in auditory temporal processing and speech-in-noise perception.
• Tinnitus significantly burdens patients, highlighting the need for comprehensive assessment of its impact.
