tinnitus?
yep,have had it to a severe level for many years and theres sometimes will even go deaf from the volume of the noise.
hyperacusis is comorbid with autistic spectrum disorders>tinnitus is associated with hyperacusis so that is one possible route, however mine was triggered by continuous brain injury from unprotected headbanging every day since toddlerhood.
because of the username [ie grahamguitarman] does that mean were/are in a band with other people and hearing amplified music regulary? that can be a cause of tinnitus;especialy if proper earplugs werent used,a support staff of mine is almost deaf in one ear from both hearing impairment and tinnitus due to being an ex death metal drummer,pillock never wore earplugs.
another possibility woud be frequencies from the electric supply,the street lights,anything on standby etc, those of us on the spectrum tend to have a higher frequency of hearing anyway and then theres the common comorbidity of hyperacusis on top [which is sensitivity to frequencies]-for example many of us are able to hear those stupid mosquito devices which are designed to stop teenagers flocking infront of shops-even when we have passed the age the body is supposed to lose this frequency,many of us are affected by those anti cat/squirrel devices to.
