Billy Bob works at the airport as a member of the ground crew. He typically takes off his hearing protection as he finds it cumbersome. Prolonged exposure to the roars of the jet engines will result in:

Sensorineural hearing loss

Explanation:

Sensorineural hearing loss happens when there is damage to the inner ear or to the nerves that travel from the ear to the brain. Sensorineural hearing loss is permanent and can make even loud noises sound muffled.

The symptoms of Sensorineural hearing loss are:

Reduced sensitivity to soft sounds

Ability to distinguish among different speech signals may suffer

Perception of loudness is affected.

Sensorineural hearing loss can be caused by loud noise exposure, especially if we are constantly exposed to sounds, both at work and outside work. Like Billy Bob, prolonged exposures to the roars of the jet engines will definetly result to this.
