|

To Assess Hearing Disability
|
| |
— Take the Air Conduction hearing threshold levels at 500Hz, 1,000Hz, 2,000Hz and 4,000Hz, add and divide by 4.
|
| |
— Do this separately for the right and left ears.
|
| |
— Subtract 20dB from the average obtained for each ear.
|
| |
This is an average hearing loss.
|
| |
— Multiply the average hearing loss of each ear by 1.25%.
|
| |
— Weight the better ear's figure by multiplying by four, add it to the worse ear's figure and divide the sum by 5.
|
| |
— Correct for the Age Related Hearing Loss by table deductions, over the age of 69 years in males and 77 years in females (Table 4).
|
| |
This figure is the Binaural Percentage Hearing Disability.
|
| |
The additional disability allowance for moderate or severe tinnitus may be added.
|
| |
This percentage computed is the proportion of hearing disability that the individual experiences, it is not the proportion of total body disablement.
