Audiology - Chapter 1

Utilization of the textbook "Fundamentals of Audiology for the Speech Language Pathologist" published by Jones and Bartlett Learning.
Availability of the 2023 third edition and the previously used second edition; both editions are suitable for the course content.
Emphasis on the importance of reading chapters from the textbook to supplement the learning experience, as not all topics will be covered in lectures.
Awareness of the American Speech-Language-Hearing Association (ASHA) standards, which govern the professional requirements for both SLPs and Audiologists.

Audiologist: Focuses on research and clinical practice related to hearing disorders, assessments of hearing, speech conservation (maintaining clear articulation despite reduced auditory feedback), and oral rehabilitation.
Speech-Language Pathologist: Specializes in evaluating and treating communication and swallowing disorders, often working as the primary point of contact for language development in children with hearing loss.
Interprofessional Practice (IPP): Collaborative modeling where multiple health workers from different professional backgrounds work together with patients, families, and communities to deliver the highest quality of care.
Challenges in Reimbursement: Audiologists currently face limitations in receiving reimbursement for aural rehabilitation services under some insurance models, often necessitating SLPs to take the lead in these therapy sessions.
Technology Coordination: Working with hearing technology such as cochlear implants and bone-anchored hearing systems (BAHS), emphasizing the need for technical troubleshooting and appropriate referrals.

Scope of Competence: SLPs should not provide services for which they are not qualified (e.g., specialized dysphagia therapy or vestibular assessments) even if it falls within the general SLP scope of practice.
Counseling: SLPs provide informational and personal adjustment counseling, helping patients navigate the psychosocial impact of hearing loss.
Conflict of Interest: Professionals must avoid practices that compromise independent judgment, such as unauthorized referral schemes or inappropriate financial incentives.

Education: SLPs promote hearing wellness by educating the public on Noise-Induced Hearing Loss (NIHL) and the importance of using hearing protection in high-decibel environments.
Early Identification: Support for Universal Newborn Hearing Screening (UNHS) to maximize the critical period for language acquisition (birth to 3 years).

Pure-Tone Screening: SLPs often perform screenings at frequencies of 1000, 2000, and 4000\text{ Hz} at a level of 20\text{ dB HL} for children.
Otoacoustic Emissions (OAEs): Utilization of portable devices to check inner ear function, providing a non-invasive "pass/fail" result.
Limitations: Screenings do not provide a threshold of hearing; they only indicate whether a full diagnostic evaluation by an audiologist is warranted.

Multidisciplinary Referrals: Coordination with Otolaryngologists (ENTs), pediatricians, and psychologists to rule out comorbidities like Autism Spectrum Disorder (ASD).
Documentation: Maintaining objective and descriptive records of screening results to facilitate the referral process.

Assistive Listening Devices (ALDs): Includes FM/DM systems and Remote Microphone Technology designed to improve the signal-to-noise ratio in classrooms.
Troubleshooting: SLPs must perform daily functional checks on hearing aids (checking batteries, earmolds, and sound quality) and cochlear implants (checking magnets and cables).
Tele-practice: Utilizing digital modalities to provide remote assessment and intervention, increasing accessibility for rural populations.

Comprehensive Evaluation: Assessing fluency, speech production (articulation/phonology), language (expressive/receptive), and cognition in the context of the patient's hearing status.
Sanitization Protocols: Strict adherence to universal precautions, including the use of gloves and disinfecting equipment used in tactile-kinesthetic exercises.

Comprehensive Assessment: Performing diagnostic tests such as Tympanometry, Acoustic Reflex Testing, and Auditory Brainstem Response (ABR).
Vestibular Function: Assessing and managing balance disorders that often co-occur with auditory issues (e.g., Ménière's disease).

Device Fitting: Selecting and programming hearing aids using real-ear measurements to ensure target gains are met.
Classroom Acoustics: Consulting on reverberation times and background noise levels (measured in dB) to suggest modifications like acoustic tiling or heavy carpeting.

Models of Disability:
- Medical Model: Views hearing loss as a condition to be "fixed" or cured.
- Social Model: Views hearing loss as a difference, where the disorder arises from societal barriers and lack of accessibility.
Deaf Culture: Identifying the distinction between "deaf" (audiological status) and "Deaf" (cultural identity using Sign Language).
Identity First vs. Person First: While person-first language (e.g., "person with hearing loss") is standard ASHA practice, many in the disability community prefer identity-first language (e.g., "Autistic person" or "Deaf person").

Obsolescence: Removal of derogatory terms like "dumb," "mute," or "handicapped" from clinical documentation.
Terminology Shift: Transitioning from "Hearing Impaired" (seen by many as negative) to "Hard of Hearing" or "D/deaf."
