Profile of hearing ratings of a job or occupation
A profile of hearing ratings of an occupation refers to the levels of hearing ability or auditory discrimination involved in the performance of the work. The ratings for hearing factors in a job profile (external link) do not indicate whether persons who are deaf or hard of hearing can or cannot perform the duties of that job. However, youth who are deaf or hard of hearing may find the information useful in terms of considering workplace accommodations that would enhance his or her employability.
