Abstract
OBJECTIVE: The purpose of the study was to analyse the role of sound avoidance and anxiety in tinnitus subjects with hyperacusis, defined as hypersensitivity to low to moderate intensity sounds. DESIGN: A group of tinnitus subjects with hyperacusis was compared to tinnitus subjects without hyperacusis, and healthy controls. For assessing noise avoidance, a questionnaire was developed (noise avoidance questionnaire, NAQ) and the duration of self-exposure to a pure tone was assessed as a behavioral index. Different self-rating instruments concerning tinnitus (STI, TF-12), hyperacusis (GÜF), and anxiety (BAI, STAI-T) were used, as well as a psychoacoustic indicator of hyperacusis (ULL). STUDY SAMPLE: Fifty-six tinnitus subjects with/without hyperacusis and 30 controls without tinnitus and hyperacusis participated in the experiment. RESULTS: The findings indicate that subjects with hyperacusis reported significantly more noise-related avoidance in daily life and show significantly shorter exposure to a pure tone than non-hyperacusic subjects, while discomfort was at the same level for each individual. Self-reported avoidance behavior correlated significantly with distress attributed to hyperacusis (r =0.81), and with anxiety ratings. CONCLUSIONS: These results suggest that hyperacusis is associated with noise-related avoidance behavior and anxiety. Systematic exposure to sound could play a significant role in the treatment of hyperacusis.
