Severe vertigo brought on by noise, sometimes accompanied by nystagmus. This condition is also called superior canal dehiscence syndrome, first identified by Lloyd Minor at the Johns Hopkins Centre for Hearing and Balance in Baltimore.

Only about 2% of the population are predisposed to this condition: their temporal bones directly above the ear's upper balance canal are abnormally thin. A slight injury or even harsh coughing may break this bone, which will cause sound to be processed improperly. The result is way-too-strong vibrations within the skull, which cause vertigo. The condition may be treated by repairing and strengthening the cracked and weakened bone.

500 Hz seems to be an especially sensitive frequency for sufferers of Tulio's.

I do not know who Tulio is.
