Tinnitus from Amp Noise

Hello...My husband was fixing an amp and the amp 'went off' LOUDLY for about 30seconds. Since February of this year, he has had tinnitus (cracking, popping, ringing, swooshing). Neither acupuncture nor homeopathy has helped. When my husband was fixing the amp, he was thinking about how much he hated being in the band he was in. Since he has tinnitus, he really can't be around music right now, so thus, no band. But the tinnitus persists. Someone suggested Vitamin D would help since they had the same problem and got over it 75%. ***** So whatever will help, please let us know.....Thanks. Tweet
