define DEAFNESS | complete/partial hearing loss or inability to hear sounds @ pitch or intensity |
define PRESBYCUSIS | gradual loss of sensorineural hearing w/age |
describe CONDUCTIVE HEARING LOSS | sound waves can't pass from air to fluid in inner ear so inadequate sound-wave conduction from outer ear to ossicles caused by earwax, infection, fluid in middle ear, punctured eardrum, otosclerosis, or scarring; generally treatable |
define SENSORINEURAL HEARING LOSS | auditory nerve/hair cells damaged from age, noise, or acoustic neuroma |
aka: sensorineural hearing loss | nerve deafness |
describe NOISE-INDUCED HEARING LOSS (NIHL) | nerve deafness caused by repeated exposure to loud or moderately loud sounds from damage to cochlea or auditory nerve; gen not noticed until some hearing permanently destroyed |
