Hearing loss is an essential knowledge of the following occupations:

Sign language teacher: Sign language school teachers educate non-age-specific students in sign language. They teach sign language to both students with or without special educational needs such as deafness. They organise their classes using a variety of lesson materials, work interactively with the group, and assess and evaluate their individual progress through assignments and examinations.
Speech and language therapist: Speech and language therapists focus on the aetiology, assessment, diagnosis, treatment, and prevention of communication and swallowing disorders in people of all ages in order to help them maintain, promote, improve, initiate, or recover the ability to communicate both verbally and nonverbally. They address the development of language, speech, vocal and hearing functions, and disorders and disabilities in the cranial, facial, and oral area.
Audiologist: Audiologists assess, diagnose and treat patients ( children or adults) with audiological and vestibular disorders caused by infectious, genetic, traumatic or degenerative conditions, such as hearing loss, tinnitus, dizziness, imbalance, hyperacusis and auditory processing difficulties. They can prescribe a hearing aid and have a role in assessing and managing patients who may benefit from cochlear implants. 
 

Hearing loss is optional for these occupations. This means knowing this knowledge may be an asset for career advancement if you are in one of these occupations.

Audiology technician: Audiology technicians create and service hearing aids and hearing protection products. They dispense, fit and provide hearing aids for those who need them.
