To compare the effects of a 20-minute acoustic stimulation (AS) with a 3-minute AS on brief acoustic tinnitus suppression (BATS) in chronic subjective tinnitus patients.
Approach:
Participants: Chronic subjective tinnitus patients aged 18-75 were recruited. Inclusion criteria included experiencing BATS and completing all experimental sessions.
Methods: Participants provided informed consent and completed psychometric questionnaires. The study was ethically approved and registered.
Key Findings:
40-90% of tinnitus patients experience BATS after AS.
BATS duration increases with longer stimulus presentation time.
No significant difference in BATS depth and duration was found between 3-minute and 6-minute AS.
Interpretation:
The effects of stimulation duration on BATS require further investigation, as existing studies suggest longer durations may enhance suppression effects.
Limitations:
The study's exploration of stimulation duration effects is limited.
Exclusion criteria may affect the generalizability of the findings.
Conclusion:
Further research is needed to clarify the impact of AS duration on BATS.
