Other Assessments and Evaluations

  • Otoscopy: performing otoscopy and ensuring appropriate follow-up, including diagnostic evaluations, intervention, and referrals
  • Self-report measures of hearing problems and their impact on daily living
  • Balance system assessment (e.g., videonystagmography (VNG), electronystagmography (ENG), and rotational tests)
  • Assessment of communication function (e.g., speech in noise testing, spatial testing, and self-report measures)
  • Assessment of tinnitus (e.g., pitch matching, loudness matching, and self-report measures)
  • Evaluating (central) auditory processes (e.g., gap detection, dichotic digits, and filtered speech)

Integrating Assessment Results

  • Integrating assessments (behavioral, physiologic, neurodiagnostic, and other evaluations)
    • to establish type and severity of hearing loss
    • to support recommendations for further evaluation and/or referral
  • Integrating balance function tests (e.g., VNG) with other results to evaluate balance function)

Documentation and Communication

  • Documenting the procedures and results of evaluations
  • Generating recommendations based on evaluations, including referrals, as appropriate, to other audiologists and related professionals
  • Communicating results and recommendations to relevant individuals (e.g., clients, caregivers, physicians, and agencies) to coordinate a plan of action
  • Interacting effectively with clients, families, other appropriate individuals, and professionals including working with interpreters (ASL and other languages, sign systems) to effectively communicate with clients


Treatment Planning

  • Evaluating client information to facilitate treatment planning (information from referral sources and case histories)
  • Selecting and modifying treatment procedures based on client factors (e.g., age, developmental level, functional status, behavior, cultural and linguistic diversity, physical, sensory, and cognitive abilities)
  • Integrating results of assessments and other evaluations to support recommendations for treatment and/or referral
