- Weber's test was developed to detect unilateral hearing loss (1)
- it compares bone conduction in both ears. It is most valuable in distinguishing
between a true and false Rinne's negative test. It is frequently done post-operatively,
to check that the ear is active.
- A vibrating 512Hz tuning fork is placed on the centre of the patients forehead.
The patient is asked whether the sound is heard in the middle or to one side.
- If the sound lateralizes (is louder on one side than the other), it suggests
- an ipsilateral conductive hearing loss
- a contralateral sensorineural hearing loss (2)
