Audiologist

Audiology (from Latin audīre, 'to hear'; and from Greek -λογία, -logia) is a branch of science that studies hearing, balance, and related disorders. Audiologists treat those with hearing loss and proactively prevent related damage. By employing various testing strategies (e.g. behavioral hearing tests, otoacoustic emission measurements, and electrophysiologic tests), audiologists aim to determine whether someone has normal sensitivity to sounds. If hearing loss is identified, audiologists determine which portions of hearing (high, middle, or low frequencies) are affected, to what degree (severity of loss), and where the lesion causing the hearing loss is found (outer ear, middle ear, inner ear, auditory nerve and/or central nervous system). If an audiologist determines that a hearing loss or vestibular abnormality is present he or she will provide recommendations for interventions or rehabilitation (e.g. hearing aids, cochlear implants, appropriate medical referrals).

In addition to diagnosing audiologic and vestibular pathologies, audiologists can also specialize in rehabilitation of tinnitus, hyperacusis, misophonia, auditory processing disorders, cochlear implant use and/or hearing aid use. Audiologists can provide hearing health care from birth to end-of-life. An audiologist is a health-care professional specializing in identifying, diagnosing, treating, and monitoring disorders of the auditory and vestibular systems. Audiologists are trained to diagnose, manage and/or treat hearing, tinnitus, or balance problems. They dispense, manage, and rehabilitate hearing aids and assess candidacy for and map cochlear implants. They counsel families through a new diagnosis of hearing loss in infants, and help teach coping and compensation skills to late-deafened adults. They also help design and implement personal and industrial hearing safety programs, newborn hearing screening programs, school hearing screening programs, and provide special or custom fitted ear plugs and other hearing protection devices to help prevent hearing loss. Audiologists are trained to evaluate peripheral vestibular disorders originating from pathologies of the vestibular portion of the inner ear. They also provide treatment for certain vestibular and balance disorders such as Benign Paroxysmal Positional Vertigo (BPPV). In addition, many audiologists work as auditory or acoustic scientists in a research capacity. Audiologists are trained in anatomy and physiology, hearing aids, cochlear implants, electrophysiology, acoustics, psychophysics and psychoacoustics, neurology, vestibular function and assessment, balance disorders, counseling and communication options such as sign language. Audiologists may also run a neonatal hearing screening program which has been made compulsory in many hospitals in US, UK and India. An Audiologist usually graduates with one of the following qualifications: MSc(Audiology), Au.D., STI, PhD, or ScD, depending the program and country attended. The use of the terms 'Audiology' and 'Audiologist' in publications has been traced back only as far as 1946. The creator of the term remains unknown, but Berger identified possible originators as Mayer BA Schier, Willard B Hargrave, Stanley Nowak, Norman Canfield, or Raymond Carhart. In a biographical profile by Robert Galambos, Hallowell Davis is credited with coining the term in the 1940s, saying the then-prevalent term 'auricular training' sounded like a method of teaching people how to wiggle their ears. the first US university course for audiologists was offered by Carhart at Northwestern University, in 1946. Audiology was born of interdisciplinary collaboration. The substantial prevalence of hearing loss observed in the veteran population after World War II inspired the creation of the field as it is known today. The International Society of Audiology (ISA) was founded in 1952 to “…facilitate the knowledge, protection and rehabilitation of human hearing” and to “…serve as an advocate for the profession and for the hearing impaired throughout the world.” It promotes interactions among national societies, associations and organizations that have similar missions, through the organization of a biannual world congresses, through the publication of the scientific peer-reviewed International Journal of Audiology and by offering support to the World Health Organization's efforts towards addressing the needs of the hearing impaired and deaf community. In Australia Audiologists must hold a Master of Audiology, Master of Clinical Audiology or Master of Audiology Studies or alternatively a bachelor's degree from overseas certified by the VETASSESS. Audiologists in Australia are not required to be a member of any professional body but to dispense hearing aids to eligible pensioners and eligible war veterans as part of the Office of Hearing Services program an Audiologist must hold a practitioner number which is obtained by obtaining a certificate of clinical practice (or equivalent) and be registered with an approved body such as Audiology Australia (AudA) or the Australian College of Audiology (ACAud). A minimum of one year of supervised practice and professional development is required post qualification to obtain this. In Australia, by general definition an 'Audiologist' - is a University graduate with postgraduate qualifications in Audiology or equivalent training. Audiologists have broad responsibilities and expertise in all non-medical areas of hearing services including complex hearing assessment and rehabilitation of hearing impairment (which includes hearing aid prescription, fitting and management). An 'Audiometrist' - has completed a TAFE Certificate Course in hearing aid audiometry and/or received in-house training from the hearing aid industry.
