BC-HIS study plan
BC-HIS · Give each week a clear focus.
8 weeks · About 6 hours per week
Hearing Instrument Technology and Electroacoustics
Define and compute the four core electroacoustic measures (gain, OSPL90, frequency response, harmonic distortion) from a manufacturer specification sheet
Differentiate compression parameters (attack, release, ratio, kneepoint) and predict how each alters output for a given input change
Compare receiver types, coupling options (dome, mold, RIC), and venting effects on the real-ear response
Interpret a speech intelligibility index or aided dynamic range outcome from a sample fitting
Your checkpoint
A one-page reference card of electroacoustic definitions plus 10 worked spec-sheet interpretation problems with answers
Hearing Instrument Technology and Electroacoustics & Disorders of Hearing and Audiologic Assessment
Trace signal flow through microphone, amplifier, DSP, and receiver and identify where each feature (noise reduction, feedback management, directional processing) operates
Classify hearing loss types and degrees using pure-tone audiometry, tympanometry, and speech recognition data
Match specific technology features to audiometric configurations that would benefit
Calculate appropriate gain targets and identify when technology-level limits constrain a fitting
Your checkpoint
A feature-to-candidacy matrix mapping at least 8 technology features to audiometric profiles with justification
Hearing Instrument Fitting, Verification, and Follow-Up Care
Select and apply a prescriptive fitting method (e.g., NAL-NL2) and explain its underlying assumptions
Perform real-ear measurement procedures and interpret REIG, REAR, and aided dynamic range results
Compare verified targets against measured output and adjust gain, MPO, and compression to close the gap
Identify and correct common fitting errors (overamplification, occlusion, feedback, underfitting of high frequencies)
Your checkpoint
A completed case-workup document for 3 sample audiograms including target values, verification steps, and adjustment rationale
Hearing Instrument Fitting, Verification, and Follow-Up Care & Disorders of Hearing and Audiologic Assessment
Design a follow-up schedule and outcome-measurement plan (e.g., speech-in-noise testing, self-report inventories) for a new fitting
Diagnose and troubleshoot feedback, occlusion, discomfort, and poor speech-in-noise performance
Differentiate counseling strategies for first-time users versus experienced users
Determine when a fitting requires reprogramming, a different coupling, or a technology change
Your checkpoint
A troubleshooting decision tree covering at least 6 common post-fitting complaints with resolution steps
Basic Sciences and Acoustics
Compute and interpret decibel conversions, sound pressure level, and dB HL versus dB SPL relationships
Explain the physics of sound transmission, impedance, resonance, and how these affect coupler versus real-ear measurements
Apply psychoacoustic principles (masking, loudness recruitment, temporal and frequency resolution) to fitting decisions
Distinguish the acoustic effects of venting, tubing length, and ear canal volume on measured output
Your checkpoint
A set of 15 solved acoustics and decibel calculation problems with a short explanation of each result
Anatomy and Physiology of the Auditory System
Label the structures of the outer, middle, and inner ear and state each structure's role in sound transmission
Describe the mechanics of the middle ear transformer and the cochlear traveling wave
Map the auditory pathway from cochlea to auditory cortex and associate each level with a clinical correlate
Relate specific pathologies (otosclerosis, otitis media, presbycusis, noise-induced loss) to their anatomic site and expected audiometric pattern
Your checkpoint
An annotated diagram-and-table study sheet linking anatomy, function, and audiometric consequence
Disorders of Hearing and Audiologic Assessment & Professional, Ethical, and Regulatory Practice
Interpret full audiologic test batteries (pure tone, speech, immittance, otoacoustic emissions) to form a differential diagnosis
Identify red flags and conditions requiring medical referral and state the referral rationale
Summarize regulatory requirements for device labeling, sale, and dispensing in the relevant jurisdiction
Apply ethical decision-making to scenarios involving sales pressure, scope of practice, and conflicts of interest
Your checkpoint
A written response to 5 case scenarios, each with diagnosis, referral decision, regulatory citation, and ethical reasoning
Professional, Ethical, and Regulatory Practice & Basic Sciences and Acoustics & Anatomy and Physiology of the Auditory System & Disorders of Hearing and Audiologic Assessment & Hearing Instrument Technology and Electroacoustics & Hearing Instrument Fitting, Verification, and Follow-Up Care
Review flagged weak areas from prior weeks and re-test those concepts under timed conditions
Integrate cross-domain knowledge by solving full-length practice items with domain tagging
Practice explaining technical concepts concisely as required by scenario-based items
Finalize a one-page summary sheet of formulas, targets, and referral criteria
Your checkpoint
A timed 100-item practice exam scored by domain, with a written remediation plan for any domain below 75%
