Sensorineural deafness: Rinne’s test positive both sides, Weber’s test lateralises away from the affected side. Key patterns:Ĭonductive deafness: Rinne’s test negative on the affected side, Weber’s test does not lateralise in either direction. If there is sensorineural deafness, the sound will be louder on the affected side. If normal, the sound should be heard at the same level in both ears when the tuning fork is placed in the middle of the forehead. It has no role in testing air conduction. The test compares bone conduction in both ears at the same time. vibrate the tuning fork and place in the centre of the forehead or on the occiput and ask whether one side is louder than the other. ![]() abnormal, with bone conduction better than air conduction) test is most commonly caused by ear wax build up or middle ear disease. While bone is a better medium for sound conduction, the terminology can be misleading, because the term ‘conduction’ refers to the passage of sound through the air, and as such, if air conduction is better than bone conduction, the Rinne’s test is counterintuitively positive.Ī Rinne’s negative (i.e. In air conduction, the sound is transmitted though the external canal, through to the middle and then inner ear.Īir conduction, in healthy individuals, should be better than bone conduction. bone conduction) with the external auditory canal (i.e. This test compares and contrasts the audible sound from a vibrating tuning fork (at 512 hertz) upon the mastoid bone (i.e.
