Weber test- screening test for hearing performed with a tuning fork. It can detect unilateral one sided conductive hearing loss middle ear hearing loss and unilateral sensorineural hearing loss inner ear hearing loss Rinne test - used to evaluate hearing loss in one ear The rinne teat differentiates sound transmitted through air conduction from those transmitted through bone conduction via the mastoid bone.
