The reasons for always feeling sound while sleeping are as follows: 1. Neurological tinnitus: It is often related to the patient’s recent work and life stress, and may also be related to the patient’s mental and emotional overstress and anxiety. Patients with long-term exposure to noisy environments or recent excessive use of headphones, as well as irregular work and rest, lack of sleep, fatigue and staying up late may trigger tinnitus symptoms, and some patients may also have varying degrees of sensorineural hearing loss. 2. Blockage of the external ear canal: This may also lead to the phenomenon of always feeling a sound when sleeping. 3. Inflammatory factors in the middle ear: This may also lead to the phenomenon of always feeling a sound when sleeping. If the phenomenon of feeling sound in the ear occurs, you need to go to the hospital for examination in time.
