The psychometric characteristics of the PB-50, CID W-22, and NU No. 6 monosyllabic word lists were compared with one another, with the CID W-1 spondaic words, and with the nine monosyllabic digits. The 583 words were spoken by the same speaker and were presented at 4 levels (−7-, −2-, 3-, and 8-dB S/N) in speech-spectrum noise xed at 72-dB SPL. Twenty-four young adults with normal hearing participated in four sessions. Recognition performance on the four lists within each of the three monosyllabic word materials were equivalent, ±0.4 dB. Likewise, word-recognition performance on the PB-50, W-22, and NU No. 6 word lists were equivalent, ±0.2 dB. The mean recognition performance at the 50% point with the 36 W-1 spondaic words was ∼6-dB better than mean performance on monosyllabic words. Recognition performance on the monosyllabic digits was 1-2 dB better than mean performance on the monosyllabic words.
