The Doctor of Audiology (AuD, sometimes written Au.D.) is a professional degree for an audiologist. The AuD program is designed to produce audiologists who are skilled in providing diagnostic, rehabilitative, and other services associated with hearing, balance, tinnitus management, and related audiological fields. These individuals help patients with hearing problems primarily by diagnosing hearing loss and fitting hearing assistive devices.
Within the AuD training program, there is an emphasis on the clinical learning experience, though most programs also have a research component.
The majority of AuD programs include three years of didactic and clinical instruction and a one-year externship. A few schools offer accelerated three-year programs. [1] Programs differ in their prerequisite requirements for admission, though broadly applicants must have some background in the natural and social sciences, mathematics, and humanities. While it may be helpful for applicants to have a background in the communication sciences, this is not generally required for admission to an AuD program.
As of 2007, in the United States the AuD has replaced Masters-level audiology programs as the entry-level degree for clinical providers. [2] Other countries, such as Australia, Canada and India, still specify the master's degree before practicing clinical audiology. In the United States, after an AuD is obtained, some states may also require a license [3] before practicing audiology clinically.
During the 20th century, the field of Audiology as a health care providing professional practice grew and developed internationally. Dafydd ("Dai") Stephens and others asserted "medical treatment and the technology by itself would not form an effective treatment and recognized that psychosocial aspects play an important role in clinical practice". [4]
In the US, the idea for the AuD creating different post-baccalaureate educational paths for research scholars (seeking MA and later-PhD degrees) and for patient-oriented, audiology health care providers was discussed by members of originated from the 1978 American Speech-Language-Hearing Association (ASHA) Task Force on Speech, Language, and Hearing Science. [5] A subsequent 1983 ASHA professional review affirmed the master's degree awarded at that time did not provide adequate practitioner/ clinical preparation, and thus in 1984 an ASHA Task Force recommended a professional doctorate (like those held by an MD, DDS, OD, etc.) be created, [6]
"At the 1987 ASHA convention in New Orleans, Rick Talbott had organized a panel discussion on the future of Clinical Audiology. The panel members were James Jerger, James Hall, George Osborne, Lucille Beck, Charles Berlin and Rick Talbott. Jerger organized a founding group of 32 audiologists who met in January 1988 for the first meeting of the American Academy of Audiology ...[at].. the second meeting of the National Task Force on Audiology in February 1988, another member of that Task Force, David Goldstein, reported on his attendance at the Founders meeting. [7]
Thereafter, at the October 1988 Academy of Dispensing Audiologists (ADA),Conference on Professional Education, the "AuD movement" was launched. [8] [9] [10]
In 1989, the Audiology Foundation of America (AFA) was formed with a charge to "transform Audiology to a doctoral profession with the Au.D. as its distinctive designator". [7] Goldstein, [11] [12] a Purdue University faculty member, and the former head of the Purdue Speech and Hearing clinic [13] served as chair of the AFA for its first ten years. George Osborn, a "founding member of the American Academy of Audiology, also played a leading role in the establishment of the doctor of audiology degree (AuD), serving as co-founder and later chairman of the Audiology Foundation of America". [8] "From the beginning, Goldstein told The Ear Hears, he was confident the AuD would succeed, despite fierce opposition, especially from the academic establishment in audiology. There had been efforts as early as 1949 to create a professional doctorate, but they had gone nowhere. But, said Goldstein, having observed the efforts of optometry and psychology to do the same thing, he had learned what worked and what didn't and had developed a plan that he believed would be successful". [10]
The AFA's goal was to " transform audiology into a healthcare profession with the Doctor of Audiology (Au.D.) as the first professional degree. The AFA is committed to fostering the education and training of these audiologists and to promoting the autonomous practice of audiology for the benefit of the general public," said Susan Paarlberg, executive director of the AFA". [14]
Goldstein "spearheaded the movement that brought that vision to life" [15] and David Goldstein is "commonly regarded as the Father of the AuD" [16] . [17] [18] David Kirkwood, former editor of TheHearing Journal wrote, "Without Dr. Goldstein's determined and tireless leadership of the AuD movement during its first 15 years or so, it's unlikely that audiology today would be anywhere close to becoming a doctoring profession". [19]
This shift in educational and training options for audiologists was not uniformly accepted. The AuD degree program "shook up the status quo" in universities resistant to the proposed changes. [15] Whereas some believed that an AuD degree would diminish knowledge levels and create a version of the profession with a lesser status, and some critics asserted there is a "point to ponder ...whether we are directing students away from the PhD course of study by virtue of developing the professional doctorate option", [20] in "the period from 1990-1992, six independent surveys reported that the majority of audiologists supported the concept of the Au.D. degree". [6]
Although the Audiology Foundation of America (AFA) disbanded after achieving its mission of transforming audiology into a doctoral profession, AFA's David P. Goldstein award, which recognizes an audiologist who made significant contributions to the profession, will live on through the ADA. "The award also holds as core values the importance of setting an example for future audiologists as well as excellence in providing quality patient care". [21]
Past Recipients
In 1934, Baylor College of Medicine established the first Au.D. program, [22] followed by Central Michigan University in 1994 and Ball State University (Indiana) in 1995. [10]
The A.T. Still University-Arizona School of Health Sciences (ATSU-ASHS) was also an early adopter of the AuD. Tabitha Parent Buck, was an undergraduate student of Goldstein's at Purdue University, became one of the first AuD graduates in the country, and went on to be a faculty member at ATSU-ASHS. [16]
Today, there are more than 100 programs offering an Au.D. degree. [1]
Audiology 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, audiologists aim to determine whether someone has normal sensitivity to sounds. If hearing loss is identified, audiologists determine which portions of hearing are affected, to what degree, and where the lesion causing the hearing loss is found. If an audiologist determines that a hearing loss or vestibular abnormality is present, they will provide recommendations for interventions or rehabilitation.
Auditory neuropathy (AN) is a hearing disorder in which the outer hair cells of the cochlea are present and functional, but sound information is not transmitted sufficiently by the auditory nerve to the brain. The cause may be several dysfunctions of the inner hair cells of the cochlea or spiral ganglion neuron levels. Hearing loss with AN can range from normal hearing sensitivity to profound hearing loss.
An Audiometrist or Audiometric Officer, is a health-care professional technician who has received special training in the use of Pure tone audiometry equipment. An audiometrist conducts hearing tests, or "audiometric screening", with an Audiometer to establish hearing levels. The results are represented by an audiogram, and are usually interpreted by an audiologist, or a registered Medical Officer, unless the audiometrist is also an audiologist, with the aim of diagnosing hearing loss.
A communicative disorders assistant (CDA) performs hearing and speech-language screenings, prepares therapy materials, implements speech therapy, reports on therapy outcomes, performs routine maintenance on clinical equipment, and works with speech-language pathologists (SLPs) and audiologists to adjust therapy goals. While CDAs cannot perform assessments or set therapy goals, they are a vital part of the therapy team. CDAs are supervised by and work in conjunction with SLPs and audiologists.
The American Speech–Language–Hearing Association (ASHA) is a professional association for speech–language pathologists, audiologists, and speech, language, and hearing scientists in the United States and internationally. The association reported over 234,000 members and affiliates in its 2023 report.
Salus University is a private university in Elkins Park, Pennsylvania, specializing in degree programs for the health care professions.
Speech–language pathology (a.k.a. speech and language pathology or logopedics) is a healthcare and academic discipline concerning the evaluation, treatment, and prevention of communication disorders, including expressive and mixed receptive-expressive language disorders, voice disorders, speech sound disorders, speech disfluency, pragmatic language impairments, and social communication difficulties, as well as swallowing disorders across the lifespan. It is an allied health profession regulated by professional bodies including the American Speech-Language-Hearing Association (ASHA) and Speech Pathology Australia. The field of speech-language pathology is practiced by a clinician known as a speech-language pathologist (SLP) or a speech and language therapist (SLT). SLPs also play an important role in the screening, diagnosis, and treatment of autism spectrum disorder (ASD), often in collaboration with pediatricians and psychologists.
Auditory processing disorder (APD), rarely known as King-Kopetzky syndrome or auditory disability with normal hearing (ADN), is a neurodevelopmental disorder affecting the way the brain processes sounds. Individuals with APD usually have normal structure and function of the ear, but cannot process the information they hear in the same way as others do, which leads to difficulties in recognizing and interpreting sounds, especially the sounds composing speech. It is thought that these difficulties arise from dysfunction in the central nervous system.
Aural rehabilitation is the process of identifying and diagnosing a hearing loss, providing different types of therapies to clients who are hard of hearing, and implementing different amplification devices to aid the client's hearing abilities. Aural rehab includes specific procedures in which each therapy and amplification device has as its goal the habilitation or rehabilitation of persons to overcome the handicap (disability) caused by a hearing impairment or deafness.
An earmold is a device worn inserted into the ear for sound conduction or hearing protection. Earmolds are anatomically shaped and can be produced in different sizes for general use or specially cast from particular ear forms. Some users specify how hard or soft they want their mold to be, an audiologist can also suggest this. As a conductor, it improves sound transmission to eardrums. This is an essential feature to diminish feedback paths in hearing aids and assure better intelligibility in noisy-environment communication. The main goal in wearing earmolds is to attain better user comfort and efficiency. Earmolds often turn yellow and stiff with age, and thus need replacement on a regular basis. Traditionally, the job of making earmolds is very time-consuming and skillful; each one is made individually in a molding process. However, new digital ear laser scanners can accelerate this process.
Marion Downs was an American audiologist and professor emerita at the University of Colorado Health Sciences Center in Denver. She pioneered universal newborn hearing screening in the early 1960s and spent over 30 years advocating for its adoption in hospitals, as well as for the provision of hearing aids to infants displaying hearing loss. Her efforts were aimed at raising awareness within the medical community about the developmental challenges associated with childhood deafness. Thanks to her initiatives, 95 percent of newborns born in America today undergo screening for hearing loss. As a result of her efforts, 95 percent of all newborns in America today are screened for hearing loss. She devoted her professional life to the promotion of early identification of hearing loss in newborns, infants, and young children and to helping deaf and hard of hearing individuals lead fulfilling lives.
Speech-Language & Audiology Canada (SAC), formerly known as the Canadian Association of Speech-Language Pathologists and Audiologists (CASLPA), is a national organization supporting and representing speech-language pathologists, audiologists, and communication health assistants. The association adopted its new name and logo on February 5, 2014.

Real ear measurement is the measurement of sound pressure level in a patient's ear canal developed when a hearing aid is worn. It is measured with the use of a silicone probe tube inserted in the canal connected to a microphone outside the ear and is done to verify that the hearing aid is providing suitable amplification for a patient's hearing loss. The American Speech–Language–Hearing Association (ASHA) and American Academy of Audiology (AAA) recommend real ear measures as the preferred method of verifying the performance of hearing aids. Used by audiologists and other hearing healthcare practitioners in the process of hearing aid fitting, real ear measures are the most reliable and efficient method for assessing the benefit provided by the amplification. Measurement of the sound level in the ear canal allows the clinician to make informed judgements on audibility of sound in the ear and the effectiveness of hearing aid treatment.
Ira Hirsh was an American psychologist who made early contributions to the field of audiology. He was the Edward Mallinckrodt Distinguished University Professor of Psychology and Audiology at Washington University in St. Louis (WUSTL) and served as president of the Acoustical Society of America.
Despite having the largest economy in South America or Central America, Brazil is still considered a developing country due to its low gross domestic product, or GDP, per capita, low living standards, high infant mortality rate and other factors. "With regard to hearing health, the Brazilian government established the national policy for giving attention to hearing health in 2004, in which the Ministry of Health, considering the social magnitude of hearing impairment in the Brazilian population and its consequences, presented the proposal to structure a network of services set up by regions and in hierarchy that aims to be implemented in all federative units of Brazil, with integrated actions to promote ear health, hearing impairment prevention, treatment and rehabilitation organized and managed by the National Health System, Sistema Único de Saúde (SUS), in Portuguese," writes Bevilacqua et al.
