Spectral-temporally modulated ripple test Lite for computeRless Measurement (SLRM): A Nonlinguistic Test for Audiology Clinics.

PMID 30870239WHAT IT FOUND
The new CD-based spectral ripple test correlates strongly with the computer-based version.
Clinicians without booth computers can use the CD test to assess spectral resolution. Scores from the two tests are interchangeable.
Key findings
01Scores from the CD-based SLRM test correlate strongly with the computer-based SMRT test.
02An increase of one correct response on the SLRM test corresponds to an increase of 0.32 ripples per octave on the SMRT test.
03The SLRM test can be administered using an audio CD, allowing evaluation in booths without computer access.

What it does not show
The study included only 20 participants. The relationship between the tests was not formally verified for predicting speech understanding, only for the correlation between the two ripple tests. The effect of cochlear implant processors on the stimulus is not fully clarified for high ripple frequencies. The SLRM duration was expected but not recorded.
Declared interests
The authors declared no conflicts of interest. The study was supported by the National Institutes of Health and non-U.S. government sources.
The easy way to misread this
Do not assume the SLRM test directly measures speech understanding. This study only proved the CD test correlates with the computer test. The link to speech performance was expected but not verified in this paper.
