The treatment for patients with acute tinnitus consists of Methylprednisolone and hyperbaric
oxygen therapy. For this study transcranial direct current stimulation (tDCS) was added to
the protocol. The purpose is to determine the effect of the time shift of tDCS. Two
conditions will be compared: tDCS simultaneously with the hyperbaric oxygen therapy or tDCS 3
weeks after the start of the tinnitus.

An audiological testing will be performed at the day of admission, after 3 weeks, 6 weeks and
12 weeks.
