Conductive hearing loss

Critical fact icon A conductive hearing loss is an increase in hearing thresholds due to a decrease in sound transmission through the external and/or middle earsAir conduction is reduced but bone transmission is unaffected.  Common causes of CHL include a ruptured eardrum, intra-tympanic fluid (usually caused by otitis media), and otosclerosis.
