The Profession of Audiology

The Profession of Audiology

Chapter One: What is an Audiologist?

  • Definition of an Audiologist:

    • 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.

Degree Changes As of 2007

  • Previous Degree Structure:

    • Masters degree program

    • 2 years post-baccalaureate degree

    • Required a Clinical Fellowship Year (CFY) after degree completion.

  • Current Degree Structure:

    • Transitioned to Doctor of Audiology (AuD).

    • Involves 3 to 4 years of post-baccalaureate education.

    • Includes a residency during the 3rd or 4th year, replacing the CFY.

PhD vs AuD

  • PhD (Doctor of Philosophy):

    • Research-oriented degree.

    • Considered a “terminal degree” in the field.

  • AuD (Doctor of Audiology):

    • Clinical degree.

    • Referred to as a “professional degree” or “entrance-level degree” into the audiology profession.

Historical Context of Audiology

  • Development of Audiology:

    • Early 1920s, post-World War I:

    • Audiology began emerging as a distinct field.

    • Identified CC Bunch as the “first audiologist.”

    • Raymond Carhart, a key student of Bunch, played a significant role in the field’s education at Northwestern University.

Evolution of Audiology Post-WWII

  • Prior to WWII, physicians and hearing aid dispensers chiefly provided services to returning veterans with hearing issues.

  • Post-WWII, audiology emerged from practices associated with otology and speech pathology.

Demographics in Audiology and Speech Pathology

  • Historical Gender Landscape:

    • Initial audiology professionals were predominantly male, unlike the split in speech-language pathology (SLP) which was 50% male and female.

  • Current Statistics (according to ASHA, 2018):

    • Audiology: 14.1% male practitioners.

    • Speech-Language Pathology: 3.7% male practitioners.

  • Note: Variability in statistics may occur based on different sources.

Recognition of Audiology as a Distinct Profession

  • In 1990, ASHA announced audiology as a distinct profession from SLP.

  • The American Academy of Audiology (founded in 1988) was formed for the exclusive representation of audiologists.

Audiologists' Relationship with ASHA

  • Not all audiologists separated from ASHA; some remained.

  • Initial motivations for separation related to financial matters but included discussions on various educational topics as well.

  • Membership Data (2021):

    • ASHA: 212,534 members.

    • Audiologists: 13,910 members.

    • Speech-Language Pathologists: 193,799 members.

    • AAA: Approximately 14,000 members.

Audiology's Current Understanding

  • Differential Diagnosis (DD):

    • The primary goal of audiologists involves differentially diagnosing the site of lesion affecting auditory function.

    • This process aims to determine the location of the problem affecting:

    • Outer ear

    • Middle ear

    • Inner ear

    • Auditory nerve

    • Central auditory nervous system

  • This process corresponds with the initial definition of audiology involving the identification and diagnosis of issues.

Audiometric Evaluations

  • A full evaluation of hearing includes:

    • Assessment of the degree of hearing loss.

    • Analysis of the slope of the configuration.

    • Evaluation of symmetry between ears.

    • Establishment of baseline for future testing.

  • It is emphasized that practical engagement in these assessments is a core part of learning outcomes for audiology students.

Management of Hearing Loss

  • Management strategies referenced include:

    • Hearing aids.

    • Cochlear implants.

    • Bone-anchored implants.

    • Hearing assistive technologies (HAT).

Clinical Practice Settings for Audiologists

  • Typical environments for audiology practice include:

    • Hospitals.

    • Schools.

    • Speech and hearing clinics.

    • Otolaryngologist’s offices.

    • Industry settings.

    • Hearing conservation agencies.

    • Hearing assistive device environments (HAs, FMs, CIs).

    • Military and VA hospitals.

    • Universities.

    • Private Practice:

    • The shift to the AuD degree is partially attributed to evolving medical policies making private practice a viable option for audiologists.

Specialties within Audiology

  • Various specialized fields within audiology include:

    • Medical Audiology.

    • Pediatric Audiology.

    • Cochlear Implant Audiology.

    • Dispensing/Rehabilitative Audiology.

    • Industrial Audiology.

    • Educational/School-Based Audiology.

Types of Audiologists

  • Clinical Audiologists:

    • Primarily work in clinical settings such as hospitals, ENT offices, and educational environments.

  • Research Audiologists:

    • Engage in research within universities, hospitals, and dedicated research centers.

  • Aural Rehabilitationists:

    • Work in hearing clinics and schools, focusing on rehabilitation efforts.

Misconceptions About Audiologists

  • Audiologists should not be confused with other professionals, such as:

    • Otolaryngologists (ENT doctors).

    • Otologists (MD specialists of the ear).

    • Hearing Scientists.

    • Deaf Educators.

    • Hearing instrument specialists or hearing aid dealers.

Professional Organizations in Audiology

  • Major organizations relevant to audiologists include:

    • American Speech-Language-Hearing Association (ASHA).

    • American Academy of Audiology (AAA).

    • Educational Audiology Association (EAA).

    • Acoustical Society of America (ASA).

    • Academy of Doctors of Audiology (ADA).

    • Academy of Rehabilitative Audiology (ARA).

  • Each state maintains its Speech-Language-Hearing Association and/or Academy of Audiology, which may include:

    • Kansas Speech-Language-Hearing Association (KSHA).

    • Pennsylvania Academy of Audiology (PAA).

Licensing and Certification

  • Certification:

    • CCC-SLP or CCC-A certifications indicate professional credentials.

  • Licensing:

    • State-issued licenses grant the authority to practice audiology.

    • Separate licensing may be required for selling hearing aids in certain states.

    • Audiologists who sell hearing aids are termed “dispensing audiologists.”

    • Continuing Education:

    • After obtaining a degree, audiologists are mandated to pursue ongoing education (CEUs or Professional Development) to maintain certifications and licenses.

    • Example requirements include 30 hours every 3-year cycle for ASHA and 20 hours for Kansas every 2-year cycle.

Scope of Practice and Code of Ethics

  • Scope of Practice:

    • Must align with evolving clinical practices in audiology, covering areas like telehealth and modern hearing technologies.

    • The scope documents outline permissible operations and emphasize independent practice under relevant ethical guidelines.

  • Code of Ethics:

    • Ethical principles upheld are essential for professional standards in audiology.

Collaboration in Healthcare

  • Interdisciplinary Cooperation:

    • Audiologists frequently collaborate with:

    • Otolaryngologists (ENTs).

    • Neurotologists practicing neuro-otology.

    • Hearing Scientists pursuing research in fields tied to audiology.

    • Audiologists provide diagnostic testing and rehabilitation, while otologists contribute additional diagnostic and medical interventions, such as surgery.
