Tinnitus
Simply put, tinnitus is ringing in the ears. Although the name implies a ringing sound, what you may hear may be similar to hissing, roaring, clicking, or buzzing. The sound could be loud, or soft, low or high pitched. Tinnitus can affect one ear only or both ears. Tinnitus is more common than you may think. According to estimates, about 10 percent of adults in the United States experiences tinnitus each year.
Although ringing in the ear is not considered a hallucination, suffering from tinnitus can raise your risk of becoming a voice-hearer. Additionally, if you also suffer from depression, your chances of experiencing hallucinations go even higher.
Hearing loss
If you suffer from hearing loss, you may hear sounds, music, or voices that are not actually there.
Studies show that auditory hallucinations are prevalent among patients with hearing impairment. The more severe your hearing loss, the worse the hallucinations get. Although researchers do not fully understand all the factors potentially contributing to this phenomenon, your doctor should evaluate your symptoms, as they may be treatable.
Epilepsy
Epilepsy is a disorder with the hallmark symptom of recurrent seizures unprovoked by any stimuli. When the repeated attacks from epilepsy affect the part of the brain that processes hearing, you might begin hearing buzzing sounds or voices. Recurring seizures can also distort how you hear things, making sounds less loud or clear.
