| BackgroundTinnitus is described as the perception of sounds or noises in the absence of real acoustic stimuli.Many therapeutic strategies have been attempted for this underlying,heterogeneous condition.The treatment of tinnitus includes drug therapy for tinnitus,psychological counseling for tinnitus,transcranial magnetic stimulation for tinnitus,habituation therapy for tinnitus,sound therapy for tinnitus,etc.Sound therapy is a common component of tinnitus treatment.Tinnitus is partially or completely masked by the use of sounds such as broadband noises,ambient sounds,etc.from a sound generator or hearing aids,lasting several hours a day.After a few months,most patients report that the impact of tinnitus on their quality of life begins to decrease,and the sound of tinnitus is relatively tolerable.Types of sounds used for tinnitus sound therapy include broadband noise,white noise,natural sounds,musical sounds of personal preference,notch sounds,ambient sounds amplified by hearing aids,and multi-flame wave sounds.Acoustic therapy uses therapeutic sounds that can be masked sounds that make tinnitus completely inaudible,or can be performed at lower intensity levels where tinnitus remains audible.In the past 10 years,there have been many new treatments for tinnitus using sound,but many conclusions about sound therapy are inconsistent,and there are differences in the evaluation of individual tinnitus patients.There is no unified patient characteristics for tinnitus sound treatment.instruction.RI（Residual Inhibition Test）refers to a method of observing the time course of masking and the properties of masking by giving a masking sound 10 d B above the threshold of the minimum masking level of the tinnitus ear for 1 minute.RI has guiding significance for the selection of tinnitus patients suitable for acoustic therapy,and most studies believe that RI-positive patients can obtain good curative effect.Based on the inconsistency of the current tinnitus sound therapy treatment conclusions,this study aimed to explore the clinical characteristics of tinnitus suitable for acoustic therapy.MethodsA total of 322 data files of tinnitus patients aged 18-88 were included in this study.All subjects were outpatients and inpatients of our department during 2019.5-2020.12.Among them,67 cases were RI positive and 255 were RI negative.All patients underwent pure-tone audiometry,tinnitus matching and residual inhibition test（RI）,and the Tinnitus Impairment Inventory（THI）,Visual Analogue Scale for Tinnitus Loudness（VAS）before and after acoustic therapy.RI-positive patients were selected as suitable acoustic treatment objects,and SPSS 22.0 software was used for statistical processing,ROC curve analysis to calculate the optimal critical value,and then Logistic regression equation and χ2 test were used to analyze.ResultsThe optimal critical values calculated by ROC curve analysis were 50.50 years old,8.50 months,THI25.00,VAS4.50,21.00 d B,4137.50 Hz,27.50 d B respectively.According to ROC curve analysis,age and tinnitus frequency have high diagnostic value.Further univariate and multivariate analysis showed that age>50.50 years old,THI<25.00,tinnitus loudness>21.00 d B,tinnitus frequency>4137.50 Hz,hearing loss>27.50 d B,bilateral tinnitus were all important related factors suitable for acoustic treatment.Disease duration and VAS were not related to acoustic therapy.ConclusionsThe basis of tinnitus sound therapy is to reduce tinnitus by increasing the external sound-driven activity of the auditory system.Acoustic therapy is a method of treating tinnitus.This study suggests that age>50.50 years old,THI<25.00,tinnitus loudness>21.00 d B,tinnitus frequency>4137.50 Hz,hearing loss>27.50 d B,and bilateral tinnitus may be suitable for acoustic therapy.relevant factors.This study reports the clinical characteristics of appropriate tinnitus acoustic therapy.However,we still need to further confirm in the follow-up multi-center,large-sample systematic observation. |
