The Self-Assessed Békesy Procedure: Validation of a Method to Measure Intelligibility of Connected Discourse.

PMID 30289020WHAT IT FOUND
A self-rating adaptive test matched standard sentence thresholds for Matrix sentences, but not for context-rich LIST sentences.
It also found stories were harder than sentences, especially with a competing talker.
Key findings
01For Matrix sentences, the new rating procedure produced speech reception thresholds that were not significantly different from the standard recall procedure in all masker conditions.
02For LIST sentences, the rating procedure produced significantly lower speech reception thresholds than the recall procedure in all masker conditions.
03For connected discourse stories, the rating procedure produced significantly higher speech reception thresholds than for sentences in all masker conditions.

What it does not show
The sample was small and homogeneous: 14 young adults with normal hearing, so results may not apply to older adults or people with hearing loss. Three participants did not finish all conditions because of an experimenter error, leaving one or three of 24 conditions missing. The connected discourse materials were nonstandardized commercial stories, so content and acoustic differences may affect results. The rating strategy was not documented, so it is unclear whether participants judged words or overall message. Variability was higher with a competing talker and for Story1, which may reflect stimulus differences rather than the procedure itself.

The easy way to misread this
Do not treat this as a ready clinical replacement for standard speech audiometry. It was tested in 14 young normal-hearing participants, and rate thresholds differed from recall thresholds for LIST sentences.
