  • The Hearing standards recommended are:

    • The applicant, when tested on a pure-tone audiometer, shall not have a hearing loss, in either ear separately, of more than 35 dB at any of the frequencies 500, 1 000 or 2 000 Hz, or more than 50 dB at 3 000 Hz.

    • An applicant with a hearing loss greater than the above may be declared fit provided that the applicant has normal hearing performance against a background noise that reproduces or simulates the masking properties of flight deck noise upon speech and beacon signals.

    • Alternatively, a practical hearing test conducted in flight in the cockpit of an aircraft of the type for which the applicant’s licence and ratings are valid may be used.

  • The person shall demonstrate acceptable hearing by at least one of the following tests:

    • Demonstrate an ability to hear an average conversational voice in a quiet room, using both ears, at a distance of 6 feet from the examiner, with the back turned to the examiner.
    • Demonstrate an acceptable understanding of speech as determined by audiometric speech discrimination testing to a score of at least 70 percent obtained in one ear or in a sound field environment.

 

  • No disease or condition of the middle or internal ear, nose, oral cavity, pharynx, or larynx that—

    • Interferes with, or is aggravated by, flying or may reasonably be expected to do so; or
    • Interferes with, or may reasonably be expected to interfere with, clear and effective speech communication.
