BC) is seen in :-Normal personIt has already been explained that air conduction is better than bone conduction, thus Rinne test is positive in normal person.Sensori-neural hearingIn sensorineural hearing loss, the defect is in cochlea or VIII nerve or its central connection. There is no defect in conductive apparatus of ear (air conduction) or in mastoid bone (bone conduction). As air conduction is better than bone conduction, Rinne test will be positive (because both air conductive apparatus and bone conductive apparatus are normal and the pathology is distal to them).o Negative test (BC > AC) is seen in: -Conductive deafnessAs the conductive apparatus is defective, bone conduction becomes better than air conduction (BC > AC).Severe unilateral sensorineural hearing lossHere the Rinne test is false negative (not true negative) as it is interpreted by the patient that BC > AC, but actually it is not. In reality this response is from the opposite ear because of transcranial transmission of sound during bone conduction testing. This can be prevented by masking the non-test ear with Barany's box while testing the bone conduction. Weber test will help for such situation.">
