 the veteran cannot reasonably attend a clinic where bone conduction HTL values can be measured;
    the veteran's other conditions are of such a degree that it will make no appreciable difference to the final assessment; or
    an ENT specialist or an audiologist has reported that:
      no air-bone gap is present;
      no conductive hearing loss is present; or
      Rinné's test is positive.

In such circumstances only air conduction HTLs need to be obtained.

4. The nature of the audiogram should be appropriate.

The nature (that is, general shape) of the audiogram should be consistent with the known hearing loss affecting the veteran and should also be consistent with other information (eg, old audiograms) concerning the veteran.

If the nature of the audiogram is not appropriate, the audiogram should be repeated or the veteran referred to an ENT specialist to clarify the situation.

Step 3: Calculate the APHL.

There are six scales labelled 7.1.3 to 7.1.8. Each scale corresponds to a different frequency of sound. Table 7.1.3 relates to 500 Hz, Table 7.1.4 relates to 1000 Hz, Table 7.1.5 relates to 1500 Hz, and so on according to their labels.
    Look up HTLs for 500Hz in Table 7.1.3 to give the loss at 500 Hz.
    Look up HTLs for 1000Hz in Table 7.1.4 to give the loss at 1000 Hz
    Look up HTLs for 1500Hz in Table 7.1.5 to give the loss at 1500 Hz
    Look up HTLs for 2000Hz in Table 7.1.6 to give the loss at 2000 Hz
    Look up HTLs for 3000Hz in Table 7.1.7 to give the loss at 3000 Hz
    Look up HTLs for 4000Hz in Table 7.1.8 to give the loss at 4000 Hz

This process gives rise to six frequency-specific losses. These six frequency-specific losses are summed to give the APHL for the relevant type of accepted deafness.

The calculations are best set out in a tabular form as below:

Accepted Hearing Loss

(Hz)  Right                Left  (%)

1000
