The Washington Hearing Impairment Calculation Worksheet is a tool used to determine a person's degree of hearing loss in the state of Washington. It is based on the American Speech-Language-Hearing Association's (ASHA) criteria for determining the severity of a hearing impairment. The worksheet involves the calculation of a person's hearing threshold levels in decibels (dB) for each of the four hearing frequencies (250, 500, 1000, and 2000 Hz). Depending on the levels of hearing impairment, the worksheet can be used to determine a person's degree of hearing loss as mild, moderate, moderately severe, severe, or profound. The Washington Hearing Impairment Calculation Worksheet is available in two versions: the Adult Version and the Pediatric Version. The Adult Version is used to assess hearing loss in adults, while the Pediatric Version is used to assess hearing loss in children. Both versions are based on the same hearing threshold calculation criteria, but the Pediatric Version has a slightly different scoring system due to the fact that children's hearing abilities differ from those of adults.

FAQ
If you have hearing loss you qualify as disabled if have: An average air conduction hearing threshold of 90 decibels or more in the good ear. An average bone conduction hearing threshold of 60 decibels in the better ear. A word recognition score of 40% or less in the better ear, as determined by standardized tests.
Results: The hearing loss for numbers a(1) is calculated as a(1)=p(1)+(50-v(1)) (p(2)-p(1))/(v(2)-v(1))-18,4 for two available measured values and as a(1)=p(1)-0,13 v(1)-11,9 if only one measured value is used, with v(i )being number intelligibility in percent at the level p(i) in decibels (dB) of measurement number i.
Increase by 1.5% for each dB above 25dB for each ear. Multiply the better ear by 5 (to weight it more heavily). Add that number with the worse ear and divide by 6 to get your hearing handicap.

An average bone conduction hearing threshold of 60 decibels in the better ear. A word recognition score of 40% or less in the better ear, as determined by standardized tests.
Typical disability ratings for hearing loss range from zero to 10 percent. However, more severe hearing losses may qualify for higher ratings. Zero percent disabilities are commonly assigned for hearing loss.
Mild hearing loss: Hearing loss of 20 to 40 decibels. Moderate hearing loss: Hearing loss of 41 to 60 decibels. Severe hearing loss: Hearing loss of 61 to 80 decibels. Profound hearing loss or deafness: Hearing loss of more than 81 decibels.
Ear-specific and better-ear 4fPTAs were used to then assign a WHO-proposed HI grade as follows: (1) normal, ?19.50; (2) slight/mild, 19.51?34.5; (3) moderate, 34.51?49.5; (4) moderately severe, 49.51?64.5; (5) severe, 64.51?80.5; and (6) profound, ? 80.51 dB HL.
