Solution

These findings suggest a defect in the middle ear.

Here's why:

  1. Weber Test: In this test, a tuning fork is struck and placed on the middle of the forehead. The sound should be heard equally in both ears. If the sound lateralizes to the unaffected ear, it suggests a conductive hearing loss in the opposite (affected) ear or sensorineural hearing loss in the same (unaffected) ear.

  2. Rinne Test: This test compares air conduction (AC) and bone conduction (BC) of sound. Normally, air conduction is better than bone conduction (AC>BC). If the air conduction-to-bone conduction ratio is less than 2:1, it suggests a conductive hearing loss.

Both these findings point towards a conductive hearing loss, which is most commonly due to a defect in the middle ear. This could be due to various reasons such as otitis media, otosclerosis, or a perforated eardrum.

The other options mentioned - otitis externa, defect in the semicircular canals, impacted cerumen, and a defect in the inner ear to the cochlear nerve - do not fit with the results of the Weber and Rinne tests as described.

Jared has been an avid fan of rock music for many years and has attended numerous concerts, getting as close to the stage as possible. He has never worn earplugs or protective earwear.
