What is Tinnitus?

Tinnitus is the perception of sound, when there is no external auditory stimulus. It can be described as a ringing, buzzing, or noise in a person’s ears. This sound can be very bothersome to some individuals. There are many theories to why this sound is perceived, but it can be a sign of hearing loss. Start with a hearing evaluation at Dunn Audiology, and potential tinnitus treatment options can be discussed.
