CAOHC EVALUATION EXAM 2026/2027 QUESTIONS
AND SOLUTIONS RATED A+
✔✔What is a general rule of conductive hearing loss? - ✔✔Flat and often worse at low
frequencies
✔✔What would be an indication of an advanced stage noise induced hearing loss? -
✔✔A notch configuration progressing to a high-frequency slope
✔✔Mixed hearing loss is a combination of what? - ✔✔Conductive and sensorineural
components
✔✔What is a symptom of sensorineural hearing loss? - ✔✔Difficulty discriminating
speech or tinnitus
✔✔What is a symptom of conductive hearing loss? - ✔✔Fullness, pressure, muffled
hearing and clarify when sound is loud enough
✔✔Peripheral functions are those associated with the? - ✔✔Cochlea
✔✔Conductive disorders are typical to which site of lesion, in contrast to NIHL? -
✔✔Outer and middle ear
✔✔Serial audiogram configurations typically shows: - ✔✔Numerical
✔✔What is the audible frequency range at birth? - ✔✔20-20,000 Hz
✔✔low/high requency Hz is subjectively interpreted as what? - ✔✔Low and high pitch
✔✔Frequency is subjectively interpreted as? - ✔✔Pitch and the number of cycles per
second
✔✔What is the speech range for most communication? - ✔✔250- 4,000 Hz
✔✔Low/high intesity (dB) is subjectively interpreted as? - ✔✔Low/ High loudness
(intensity corresponds to loudness)
✔✔The Action level is at what dB? (requires HCO implementation i.e. hearing testin,
program inclusion, hpd) - ✔✔85 dB
✔✔Permissible exposure level is at what dB? - ✔✔90 DB
✔✔What is the concept of steady state noise? - ✔✔Long duration (>.5) i.e engine noise
