The Washington Hearing Impairment Calculation Worksheet is a tool used in the state of Washington to calculate an individual's hearing impairment. It is used to determine the extent of the hearing impairment in order to determine the amount of compensation or services an individual may be eligible for. The Worksheet has two versions: the Standard Worksheet and the Complex Worksheet. The Standard Worksheet is used for individuals with a hearing impairment that is primarily caused by either noise exposure, a sudden hearing loss, or a combination of both. It uses a set of criteria to determine the individual's overall hearing impairment. The criteria include the individual's hearing threshold levels, as well as the degree of hearing loss in each ear. The Complex Worksheet is used for individuals with a hearing impairment caused by a combination of factors, such as an underlying medical condition, a congenital hearing disorder, or exposure to noise. It takes into account additional factors, such as the individual's age, hearing abilities, and speech recognition levels. Both the Standard Worksheet and the Complex Worksheet are used to calculate the individual's hearing impairment and determine the amount of compensation or services they may be eligible for.
