Air Force Hearing Standards: The following are conditions related to ear and hearing standards

Free Field hearing loss is a reason for rejection in the speech test. Any CV/FW reduction of less than 600 cm is unacceptable.
Audiometric Loss: In frequencies between 250 and 8000 Hz, audiometric loss should not exceed 20 dB. An isolated unilateral hearing loss of up to 30 decibels may be tolerated on the advice of an ENT specialist if the ENT examination is otherwise normal.
Even if the mastoid is completely epithelialized and good hearing is preserved, a radical/modified radical mastoidectomy results in rejection. Previously performed cortical mastoidectomy with the tympanic membrane intact, normal hearing, and no evidence of disease may be accepted.
Chronic otitis externa with exostoses or excessively narrow meat will be rejected. The canal’s exaggerated tortuosity, which obliterates the anterior view of the tympanic membrane, will result in rejection.
Twelve weeks after surgery, tympanoplasty Type I is acceptable if the ear clearance test in the altitude chamber is normal. The following conditions in the middle ear will result in rejection: – Perforation in the attic, central, or periphery.
Scar on the tympanic membrane with significant retraction.
Type II and later tympanoplasty, but not type I.
If calcareous plaques occupy more than 1/3 of the pars tensa, it is called tympanosclerosis.
Infection in the middle ear.
In the external auditory canal, there is granulation or a polyp.
The procedure is known as a stapedectomy.
Meniere’s disease is a condition that affects the inner ear.
Vestibular dysfunction, including vestibular nystagmus.
Following an ear infection, Bell’s palsy develops.

Past medical history of diseases or injuries of the spine or sacroiliac joints, with or without objective signs that have prevented the candidate from successfully leading a physically active life, is a reason for rejection for commissioning in the IAF. Rejection is likely if you have a history of spinal fractures or a prolapsed intervertebral disc, as well as surgical treatment for these conditions. A candidate for Air Force service will be disqualified if the following conditions are discovered during the medical examination.

The spine’s granulomatous disease
Rheumatoid arthritis and related disorders are examples of arthritis/spondylosis.
Ankylosing spondylitis is a type of arthritis that affects the spine.

Dislocation of the TMJ due to a mouth opening of less than 30 mm measured at the incisal edges.
All of these conditions have the potential to be cancerous.

Submucous fibrosis with or without restriction of mouth opening is diagnosed clinically.
Gross visible calculus, periodontal pockets, and/or gum bleeding are all signs of poor oral health.

Chest Problems
Tuberculosis, or evidence of tuberculosis, pulmonary lesions, heart lesions, and musculoskeletal lesions of the chest wall are all rejected.
