“…Many tinnitus patients suffer from persistent and high pitch tinnitus with negative emotional experiences, including anxiety, depression, insomnia and attention deficits (Langguth et al., 2007; Alster et al., 1993; Hallam et al., 2004). Although many diseases are known to lead to auditory dysfunction and tinnitus, noise exposure is one of the key causes (Halford and Anderson, 1991; Adoga et al., 2015; Bartels et al., 2008). Occurrence of tinnitus may also be closely related to age and psychological factors.…”
