What Is Tinnitus?
Tinnitus is the perception of sound when there is no external sound source present. It may be experienced in one or both ears and can vary from occasional and mild to persistent and disruptive.
People may perceive tinnitus as ringing, buzzing, hissing, clicking, humming, or whooshing sounds. In some cases, the sound may resemble music, water running, or other familiar noises.
Types of Tinnitus
1. Subjective Tinnitus
Subjective tinnitus is the most common type and can only be heard by the person experiencing it. It is often associated with changes or problems within the auditory system, including the inner ear, auditory nerve, or areas of the brain involved in processing sound.
2. Objective Tinnitus
Objective tinnitus is uncommon and, in some cases, may also be detectable by another person or a healthcare professional. It can be associated with factors such as blood vessel abnormalities, middle-ear conditions, or muscle contractions around the ear. It may sometimes be perceived as a rhythmic pulsing, clicking, or whistling sound.
