Purpose: The purpose of this study was to determine to compare the effects of sound therapy depending on air- and bone-conduction transducers (ACT and BCT). Methods: Participants were twenty adults who have diagnosed as subjective tinnitus in this study. All participants conducted a sound therapy using the level of mixing point for three months. Participants were randomly assigned to different groups, such as the ACT group, or BCT group. To identify the effects of sound therapy, Korean tinnitus primary function questionnaire (K-TPFQ) and visual analogue scale (VAS) were administered at pre- and post-treatment (3 months) sessions. Results: In a result of mixed model analysis of variance, all subcategories for VAS showed significant decrements of scores to the measurement session (pre- vs. post-session), but there was no different between groups. Also, the overall and all subcategories for K-TPFQ showed significant decrements of scores to the measurement session (prevs. post-session), but there was no different between groups. Conclusion: As a result of this study, the sound therapy using portable hearing devices with transducers is effective for subjective tinnitus sufferers. Because the transducer type does not significantly affect effectiveness of the sound therapy, therefore, audiologists or hearing professionals may recommend transducers, which the tinnitus sufferer prefers when they consider sound therapy.

Abstract Background: Many neuroanatomical alterations have been detected in patients with tinnitus in previous studies. However, little is known about morphological and structural covariance network (SCN) changes before and after long-term sound therapy. This study aimed to explore alterations in brain anatomical and SCN changes in patients with idiopathic tinnitus using voxel-based morphometry (VBM) analysis 24 weeks before and after sound therapy. Methods: Thirty-three tinnitus patients underwent magnetic resonance imaging scans at baseline and after 24 weeks of sound therapy. Twenty-six age- and sex-matched healthy control (HC) individuals also underwent two scans over a 24-week interval; 3.0T MRI and high-resolution 3D structural images were acquired with a 3D-BRAVO pulse sequence. Structural image data preprocessing was performed using the VBM8 toolbox. The Tinnitus Handicap Inventory (THI) score was acquired in the tinnitus group to assess the severity of tinnitus and tinnitus-related distress. Two-way mixed model analysis of variance (ANOVA) and post hoc analyses were performed to determine differences between the two groups (patients and HCs) and between the two scans (at baseline and at the 24th week). Two-sample t tests, paired-samples t tests, and Pearson’s correlation analysis were used in the post hoc analysis.Results: Interaction effects between the two groups and the two scans demonstrated significantly different gray matter (GM) volume in the right parahippocampus gyrus, right caudate, left superior temporal gyrus, left cuneus gyrus and right calcarine gyrus; we found significantly decreased GM volume in the above five brain regions among the tinnitus patients before sound therapy (baseline) compared to that in the HC group. The 24-week sound therapy group demonstrated significantly greater brain volume compared with the baseline group among these brain regions. We did not find significant differences in brain regions between the 24-week sound therapy and HC groups. The SCN results showed that the left superior temporal gyrus and left rolandic operculum were significantly different in nodal efficiency, nodal degree centrality and nodal betweenness centrality after FDR correction. Decreased THI scores and GM volume changes between the left thalamus and right thalamus were not correlated. Conclusions: This study characterized the effect of sound therapy on brain GM volume, especially in the left superior temporal lobe. Notably, sound therapy had a normalizing effect on tinnitus patients.

Background: Bone-conduction thresholds have been used in audiologic assessments of both infants and adults to differentiate between conductive and sensorineural hearing losses. However, air- and bone-conduction thresholds estimated for infants with normal hearing using physiological measures have identified an “air–bone gap” in the low frequencies that does not result from conductive hearing impairment but, rather, from maturational differences in sensitivity. This maturational air–bone gap appears to be present up to at least 2 yr of age. Because most infants older than 6 mo of age are clinically assessed behaviorally, rather than physiologically, it is necessary to determine whether a similar maturational air–bone gap is present for behavioral air- and bone-conduction thresholds. Purpose: The purpose of this study was to estimate behavioral bone-conduction thresholds for infants using a standard clinical visual reinforcement audiometry (VRA) protocol to determine whether frequency-dependent maturational patterns exist as previously reported for physiological bone-conduction thresholds. Research Design: Behavioral bone-conduction minimum response levels were estimated at 500, 1000, 2000, and 4000 Hz using VRA for each participant. Study Sample: Young (7–15 mo; N = 17) and older (18–30 mo; N = 20) groups of infants were assessed. All infants were screened and considered to be at low risk for hearing loss. Data Collection and Analysis: Preliminary “normal levels” were determined by calculating the 90th percentile for responses present as a cumulative percentage. Mean bone-conduction thresholds were compared and analyzed using a mixed-model analysis of variance across frequency and age group. Linear regression analysis was also performed to assess the effect of age on bone-conduction thresholds. Results: Results of this study indicate that, when measured behaviorally, infants under 30 mo of age show frequency-dependent bone-conduction thresholds whereby their responses at 500 and 1000 Hz are significantly better than those at 2000 and 4000 Hz. However, thresholds obtained from the younger group of infants (mean age of 10.6 mo) were not significantly different from those obtained from the older group of infants (mean age of 23.0 mo) at any frequency. Conclusions: The findings of the present study are similar to the results obtained from previous physiological studies. Compared to previously documented air-conduction thresholds of infants using similar VRA techniques, a maturational air–bone gap is observed in the low frequencies. Therefore, differences between infant and adult bone-conduction thresholds persist until at least 30 mo of age. As a result, different “normal levels” should be used when assessing bone-conduction hearing sensitivity of infants using behavioral methods.

Purpose: This study aimed to identify the effects of sound therapy according to various types of stimuli for 3 months in people with chronic tinnitus.Methods: Fifty-eight participants with chronic tinnitus based on inclusive and exclusive criteria were randomly assigned to one of the three groups: broadband noise group, nature sound group, and music sound group. Each group received sound therapy for 3 months and the level of stimulus was set to the level of the mixing point. To measure the change in participants’ tinnitus, the Korean version of the Tinnitus Primary Function Questionnaire (K-TPFQ) was used at the initial and 3-month follow-up sessions.Results: In the mixed model analysis of variance, the main effects of time were significant in almost all the K-TPFQ categories, except for the hearing category. However, the main effect of groups was not significant in most of the K-TPFQ categories, except for the sleep category. The main effects of interaction with group × time were not significant.Conclusion: The results of this study indicate that sound therapy for 3 months could be effective in the management of tinnitus. However, no difference in the effect of sound therapy according to the type of stimuli was noted. These results show that sound therapy could be an effective method for people with tinnitus, regardless of the type of stimulus.
