It might be tinnitus, which is the perception of noise or ringing in the ears. Generally, it's a symptom of an underlying condition, such as age-related hearing loss, ear injury or a circulatory system disorder. Although bothersome, tinnitus usually isn't a sign of something serious. Although it can worsen with age, for many people, tinnitus can improve with treatment. Treating an identified underlying cause sometimes helps. Therefore, you need to consult an ENT doctor to confirm the cause.
