Objective: Tailor-made notched music was applied to alleviate the symptoms of chronic idiopathic tinnitus and compared its effectiveness with other existing sound treatment of tinnitus.
Methods: Subjects (
n=43; ears=75 )were recruited during June 2015 to October 2016 from the out-patients of our hospital. These patients had chronic (longer than 6months) and idiopathic tinnitus, with or without significant sensorineural hearing loss. In the prospective design, the patients were randomly divided into group A (treated with tailor-made notched music) and group B (treated with analogous sound masking), and received the treatment for 3 months. The tinnitus scale, tinnitus questionnaire and audiological findings were evaluated before treatment, and at one month and three months after treatment started.
Results: After onemonth of treatment, the effective rate between the two groups was 40.9% and 42.9%, there was no significant difference between the two groups (χ(2)= 0.017,
P=0.897). The average VAS for patients in group A showed more decrease in group A than in group B(VAS: 1.8
vs. 0.8, the percentage : 29.5%
vs. 13.6%), but there was no significant difference between the two groups (
t=-1.450,
P=0.155). After 3 months of treatment, the effective rates were 68.2% and 23.8%, respectively. There was significant difference between the two groups (χ(2)= 8.503,
P=0.004). The difference of the VAS scores between the two groups was statistically significant (
t=-3.263,
P=0.002), and the VAS score of group A was less.After 3 months of treatment, there was significant decreaseinthe average tinnitus loudness for patients in group A(
t=5.569,
P<0.01), and there was no significant changein group B(
t=-0.953,
P=0.374). There was also significant decreasein the scores of tinnitus handicap inventory (THI) (
F=7.334,
P<0.05), loudness visual analog scale (VAS) (
F=20.48,
P<0.001), and the proportion of patients with moderate to severe tinnitus(χ(2)=11.289,
P<0.05) in the group A, and there was no significant change in group B(
F=2.198,
F=0.989, χ(2)=1.651;
P=0.120,
P=0.378,
P=0.438>0.05).
Conclusions: Our resultssuggest that long-term normalized listening to tailor-made notched music, can significantly reduce the perceived tinnitus loudness in varying degrees and improve the quality of life of patients. The effects and possible mechanism of this method were discussedin this paper.
