Final answer:
Weber's test and Rinne's test are used to assess hearing loss. In Rinne's test, a vibrating tuning fork is placed on the mastoid process and then moved to the ear canal. In Weber's test, a tuning fork is placed on the skull to determine the laterality of hearing loss.
Step-by-step explanation:
The Weber's test and Rinne's test are performed to assess hearing loss.In the Rinne's test, a vibrating tuning fork is placed on the mastoid process behind the ear, and the patient indicates when the sound is no longer heard. Then, the fork is moved just next to the ear canal. If the sound is not heard through the ear, it indicates conductive hearing loss. In the Weber's test, a tuning fork is placed at the top of the skull, and the sound of the tuning fork reaches both inner ears by traveling through bone. With unilateral conductive hearing loss, the tuning fork sounds louder in the ear with hearing loss, while with unilateral sensorineural hearing loss, the tuning fork sounds quieter in that ear.
