Rinne test
Normal hearing = POSITIVE. Air conduction is louder than bone conduction.Conductive hearing loss = NEGATIVE. Bone conduction is better than air conduction.
Sensorineural hearing loss = POSITIVE because both bone air and bone conduction are equally reduced (NB: may need to mask normal ear to avoid a false negative from the opposite side).
Weber test
Normal hearing = sound comes from middle of forehead.Unilateral conductive hearing loss = sound is loudest in AFFECTED ear because the ambient noise is picked up by the normal ear, masking the sound of the tuning fork on that side.
Unilateral sensorineural hearing loss = sound is loudest in UNAFFECTED (normal) ear.
