Dr Ronald Chin’s Explanation of the Weber Test

You perform the Weber test by striking the tuning fork and gently pressing it against the centre of the person’s forehead.

In a person with normal hearing, the sound from the tuning fork travels equally to both ears. This happens because the vibrations properly transmit through the middle ear, and ear canals are received symmetrically by the cochlea.

However, if a person has conductive hearing loss, something is blocking the sound from escaping correctly. So, you’ll find it louder in the impaired ear. The cochlea receives more energy or vibration because it’s trapped, making it seem louder to us.

On the other hand, if a person has sensorineural hearing loss, the sound will appear quieter in the impaired ear. This is because there is a problem with the cochlea or the nerves connected to it, which reduces the ability to pick up the vibrations and transmit them to the brain.
