AB  - Occupational  hearing  loss  may  be  partial  or  (rarely)  total,  unilateral  or  bilateral,  and  conductive,  sensorineural,  or  mixed  (conductive  and  sensorineural).  Conductive  hearing  loss  involves  the  external  or  middle  ear,  and  impairs  the  passage  of  sound  to  the  inner  ear;  sensorineural  hearing  loss  (SNHL)  results  from  dysfunction  of  the  inner  ear,  auditory  nerve,  or  brain.  In  the  workplace,  conductive  and  mixed  hearing  loss  can  be  caused  by  blunt  or  penetrating  head  injuries,  explosions,  and  thermal  injuries  such  as  slag  burns  sustained  when  a  piece  of  welder's  slag  penetrates  the  eardrum.  SNHL  usually  results  from  damage  to  the  cochlea,  especially  loss  of  hair  cells  from  the  organ  of  Corti.  Among  the  causes  of  occupational  SNHL  are  continuous  exposure  to  noise  in  excess  of  85  dBA,  blunt  head  injury,  and  exposure  to  ototoxic  substances.
