Characteristics of the range of intensities yielding PB Max and of the threshold for monosyllabic words (PBT) were investigated in 110 elderly subjects with mild-to-moderate sensorineural hearing loss. Word recognition functions were generated using the Auditec recordings of the CID W-22 words with 50 words per level. The results indicated that (a) the range of intensities yielding PB Max was approximately 33 dB at a level corresponding to 12% below PB Max, (b) the PB Max range decreased as the magnitude of hearing loss increased, (c) testing at the loudness discomfort level was likely to provide a more accurate estimate of PB Max than testing at most comfortable listening level, (d) word recognition scores should be obtained at a minimum of two intensities in order to estimate PB Max, (e) the PBT in dB SL re the spondaic threshold increased as the steepness of the audiogram increased, and (f) the PBT should not be considered unusual unless it exceeds the predicted value by about 14 dB.
