A healthcare professional, specializing in identifying, diagnosing, treating, and monitoring the disorder of vestibular and auditory system is called an audiologist. They are trained to diagnose, and treat hearing problems.
An audiologist is a health professional who undergoes training through clinical work and education to diagnose, test for, and help people compensate for hearing problems. When the problem is diagnosed, healthcare professionals guide people to cope with such disorders, or give recommendations for medical treatment that end or address these problems. An audiologist works in vast variety of settings, and is also trained to work with small children to adults of all ages. Some work with schools to provide screening and diagnosis of hearing problems in the very young. Later on, they may specifically work with children who are hearing impaired, and give suggestions to parents on how to address the disorder.
For an audiologist one should have at least a master's degree in audiology, but a doctoral degree will help in making a bright career. Also, a license is necessary to practice as an audiologist.
