A 45-yeаr-оld mаn presents tо the clinic cоmplаining of hearing difficulty in his left ear following an episode of otitis media. You decide to perform a Rinne test to help determine the type of hearing loss. You place a vibrating 512 Hz tuning fork first on the mastoid process behind his left ear. He indicates when he no longer hears the sound. Then you quickly hold the vibrating fork just in front of his left ear canal and ask if he can still hear it. Based on your testing, the patient reports hearing the sound louder and longer when the tuning fork is on his mastoid process compared to when it is held near his ear canal on the left side. What does this finding most likely indicate?
