Tinnitus requires examinations, including the condition of the external auditory canal and tympanic membrane and pure tone audiometry, as follows:

1. The condition of the external auditory canal and tympanic membrane: can be checked through an electronic otoscope.

2. Pure tone audiometry: It can evaluate whether there is hearing loss. Some patients with tinnitus have very slight hearing loss and the patient cannot feel the hearing loss.

3. Middle ear tympanogram: It is necessary to evaluate the condition of the middle ear and whether there is otitis media.

4. Tinnitus assessment: Match the sound frequency and intensity of tinnitus, and fill in a tinnitus questionnaire to evaluate the impact and extent of tinnitus on the patient's psychology and sleep, as well as whether there is anxiety, depression, etc.
