Which test would be appropriate to confirm that a patient's responses reflect true thresholds when traumatic brain injury may affect test directions?

Which test would be appropriate to confirm that a patient's responses reflect true thresholds when traumatic brain injury may affect test directions?

• A. Tympanometry
• B. Acoustic-reflex thresholds
• C. A word-recognition test
• D. Speech-awareness or speech-recognition thresholds

Answer: (D)

When a patient’s ability to follow directions may be compromised by traumatic brain injury, you want a measure that ties the response to actual speech perception at a low level. Speech-awareness or speech-recognition thresholds do just that: they establish the quietest level at which the patient can detect or recognize speech. This reduces the influence of cognitive demands and test-taking behavior because you’re looking at a true perceptual threshold rather than requiring complex instructions or precise word repetition. Tympanometry and acoustic-reflex thresholds assess middle-ear function and reflexes, not the patient’s actual speech hearing threshold, and they don’t address whether the patient is perceiving speech at threshold levels. A word-recognition test relies on correctly repeating words, which can be heavily affected by attention, memory, language skills, and compliance—factors that can distort threshold estimates in someone with brain injury. So using speech-awareness or speech-recognition thresholds provides a more reliable check that responses reflect genuine auditory thresholds in this context.
