Tinnitus is a common clinical symptom; it is not a disease. Tinnitus usually refers to the subjective sensation of sound in the ear or head in the absence of any corresponding external sound source or electrical stimulation, i.e. subjective tinnitus, or tinnitus for short. In a broad sense, tinnitus also includes objective tinnitus, which has a corresponding sound source, such as a vasogenic or myogenic murmur. Tinnitus is partly caused by organic diseases such as neurological and cardiovascular diseases, and partly caused by emotional stress and anxiety. For the latter type of patients, it is effective to change the sleeping environment with “white noise”. White noise is a frequently distributed sound, such as the rustling of wind-blown leaves, the sound of waves, the sound of air conditioning blowing, etc. It is considered by the Western medical profession as a “harmonious” therapeutic sound, which can play a role in the treatment of some neurological diseases. When the tinnitus is appropriate to play a little white noise, such as playing an alarm clock, electric fan, etc., can make the ear buzzing, roar, etc. by its “shielding”, is conducive to the relief of tension and anxiety.
