Abstract
OBJECTIVE: The Speech in Babble (SiB) test assesses the perception of speech in noise in UK adults. Here, we define the normal range of SiB scores to enable the use of the test in clinic. DESIGN: In each test, 25 monosyllabic words were played in background multi-talker babble. Listeners had to repeat the word they heard. An adaptive procedure was used to determine the signal-to-noise ratio needed to reach 50% correct responses (i.e. the Speech Reception Threshold). Eight distinct equivalent lists were available. STUDY SAMPLE: Sixty-nine normal-hearing adults (aged 20–57 years) with no reported listening difficulties participated in the study and completed the SiB test twice in both ears. RESULTS: Normative SiB scores varied from −0.8 dB to 3.7 dB suggesting that patients outside these limits should be considered as having abnormal scores. No statistically significant difference between ears and no effect of age or sex was found. There was “fair” test-retest reliability. CONCLUSION: The SiB test is a short, valid and reliable test that can be used in UK clinics, e.g. as part of a standard APD battery or evaluating the performance of hearing impaired patients.
