Hearing standards, all questions in this thread please I SAID HEARING STANDARDS, ALL QUESTIONS IN THIS THREAD. Now that we have the obligatory joke about hearing over and done with, we can concentrate on the serious side of hearing standards for recruits. All new entrants must have hearing acuity assessed by pure tone audiometry. Audiometric basis of assessment. The basis of audiometric assessment is the summing of high and low frequency levels in decibels (dB) over 6 frequencies. The frequencies used are 0.5, 1, 2, 3, 4, 5 and 6 Kilohertz (kHz); The low frequencies being 0.5, 1 and 2 kHz and the high frequencies being 3, 4, and 5kHz. The hearing in each ear is assessed separately. The assessment is recorded under the first H for right ear, and under the second H for the left ear. The higher digit representing the worst frequency group, determines the individuals overall hearing category for each ear. Audiometric standards, There are five grades of hearing acuity 1, 2, 3, 4, and 8. Specialist advise will need to be sought to determine H4 and H8 See the attachment below for details translation of the above, you have to have an audio test. each ear is assessed by a variety of tones in set frequencies. The frequencies are split into high and low. Check these against the table (link above) and you'll find out if you are too deaf to join. Most trades only require H2, AAC soldiers and pilots* require H1, AGC MPGS* are accepted as H3. Soldiers who become a lower hearing grade during service may be retained. * no direct entry for AAC pilots and MPGS anyway.
