Conductive and SNHL

what is the conductive portion of the ear?

outer and middle

what is the sensoineural portion of the ear?

inner ear and auditory nerve

bone conduction

assesses the sensory/neural pathway only

air conduction

assesses both pathways

describe conductive hearing loss

due to a barrier to sound transduction through the outer and/or middle ear

consequence of CHL

sound attenuation

describe SNHL

due to a disturbance situated in the inner ear and/or the neural pathway

testing result of CHL

impaired AC, normal BC

consequence of SNHL

sound attenuation and sound distortion if the loss is great enough

result of SNHL

impaired AC and nearly equivalently impaired BC

mixed HL

due to a barrier to sound transmission in OE and ME as well as a disturbance in IE and/or neural pathway

consequence of MHL

sound attenuation and sound distortion if the BC loss is great enough

testing result of MHL

impaired AC, impaired BC with AC impairment being greater than BC impairment
