The most common cause of<unk>  is overexposure to excessively high decibel (sound pressure) levels. Some sufferers acquire<unk>  suddenly as a result of taking ear sensitizing drugs, Lyme disease, Ménière's disease, head injury, or surgery. Others are born with sound sensitivity, develop superior canal dehiscence syndrome, have had a history of ear infections, or come from a family that has had hearing problems. Bell's palsy can trigger<unk>  if the associated flaccid paralysis affects the tensor tympani, and stapedius, two small muscles of the middle ear. Paralysis of the stapedius muscle prevents its function in dampening the oscillations of the ossicles, causing sound to be abnormally loud on the affected side. Some psychoactive drugs such as LSD, methaqualone, or phencyclidine can cause<unk> . An antibiotic, ciprofloxacin, has also been seen to be a cause, known as ciprofloxacin-related<unk> . Benzodiazepine withdrawal syndrome is also a possible cause.
