Which of the following statements is true about the tuning fork test used in hearing assessments?

The tuning fork test is an important clinical tool used to assess hearing, specifically to differentiate between conductive and sensorineural hearing loss. The correct statement is that the fork is placed on the mastoid process. This placement is a crucial part of the Rinne test, which compares bone conduction (BC) and air conduction (AC) of sound.

When the tuning fork is struck and then placed on the mastoid process, it vibrates and transmits sound through the bones of the skull directly to the inner ear. This allows the examiner to assess how well sound is conducted through the bones. The patient is then asked to indicate when they can no longer hear the sound, after which the fork is moved to the front of the ear canal to compare air conduction. The ability to hear the sound longer through air than through bone would indicate normal or sensorineural hearing, while the opposite would suggest conductive hearing loss.

The other statements are not accurate representations of the tuning fork test. It is not placed on the earlobe, as this location does not provide the necessary bone conduction assessment. The tuning fork does not measure air conduction only; it plays a role in assessing both air and bone conduction. Lastly, the tuning fork itself does not provide a
