You can demonstrate this by speaking/humming, and then occluding an external auditory meatus. In addition, low-frequency sounds are ‘trapped’ within the inner ear by the obstruction leading to increased loudness in the affected ear. The affected ear has less environmental noise (due to the problem with air conduction). *In conductive hearing loss, there is a relative improvement in bone conduction on the affected side.
