Welcome to the forum. Acoustic trauma from loud noise exposure is only one of many possible causes of tinnitus. There are many causes which can trigger or aggravate tinnitus including but not limited to drug reaction or side-effects from ototoxic drugs, ear wax build-up, ear or Eustachian tube infection or ETD, ear drum injury, fluid build-up in ears feeling pressured or fullness, sinus infection & congestion especially with a bad cold, TMJ, TTTS, high blood pressure or blood circulation problem, loud noise exposure or acoustic trauma/shock, head trauma & injury, neck injury or muscle problems, hearing loss, Meniere's Decease, barotrauma from sudden change of air pressure such as during landing & taking off on flights especially with blocked nose causing failure to balance the pressure changes, slapping of the ears, deep grief for the loss of loved ones, untreated sleep apnea, extreme, extended stress, anxiety & panic disorder, etc., etc.
Being young at 16 may be helpful as young people tend to adapt better and recover faster from T. Many young people get better and wrote their success stories. Here are some such young posters with their stories below. Take good care. God bless.
