“…Currently, many therapeutic approaches have been applied in the process of idiopathic tinnitus treatment, such as counseling and psychoeducation, pharmacological treatments, sound therapy, hearing aids, tinnitus retraining therapy, cochlear implants, brain stimulation, hyperbaric oxygen, and acupuncture (Langguth et al, 2013;Zenner et al, 2017). Among these therapeutic measures, sound therapy, such as frequency unmodulated noise generators involving the use of recorded noise, special tinnitus noisers, or tinnitus masker devices (Jastreboff, 1999;Oishi et al, 2013;Zenner et al, 2017), has been widely used in the treatment of idiopathic tinnitus in many studies (Han et al, 2020;Jastreboff, 1999;Lv et al, 2020;Oishi et al, 2013;Wei et al, 2020). Furthermore, it has been listed as an option in clinical practice guidelines (Henry, Schechter, Nagler, & Fausti, 2002;Tunkel et al, 2014) and even used as a first-line means for treating tinnitus patients when combined with other measures, such as hearing aids and information and counseling (Hoare, Edmondson-Jones, Sereda, Akeroyd, & Hall, 2014;Hobson, Chisholm, & El, 2012;Sereda, Hoare, Nicholson, Smith, & Hall, 2015;Tutaj, Hoare, & Sereda, 2018).…”
