Type, degree and slope of loss predicted from family history, childhood illness, noise and acoustic trauma, trauma and otalgia, systemic disease and ototoxic medication, and prior ear surgery; lifestyle impact; medical-referral scenarios; preventative hearing protection selection; and hearing loss vs. lack of understanding.

Otoscopic findings and cerumen management, degree and type of loss from air and bone conduction, tympanometry and acoustic reflexes, tinnitus management, SAT vs. SRT, word recognition, masking adequacy, MCL/UCL and recruitment, speech-in-noise results, irregular/non-organic results, referral indicators, surgical candidacy, and transducer selection.

Hearing instrument selection by style, configuration, matrix and power source; telephone options; assistive listening devices; IIC contraindications; ear impression procedure and material modifications; tube, dome, earmold and receiver selection for OTE, RIC and BTE; custom vs. non-custom trade-offs; and CROS/BiCROS for asymmetrical loss and SSD.

Adjustment from objective verification (sound-field aided/unaided warble tones and narrow-band noise, real-ear measurement and speech mapping), modifying the physical fit of earmolds and custom shells, adjustment from subjective validation, programming troubleshooting, obstruction/moisture/battery faults, and wireless pairing.

Explaining otoscopic and audiometric findings to patients, limitations and benefits of amplification, counseling driven by subjective validation results (COSI, IOI-HA, APHAB), communication strategies for different listening environments, and the manual adjustments patients, family members, and caregivers can make.
