The present study examines the relation between the form of the loudness function and the size of the intensity just noticeable difference (jnd). The hypothesis that equal loudnesses at any given sound frequency yield equal-intensity jnd's was examined. In addition, Hellman et al.'s [J. Acoust. Soc. Am. 82, 448-453 (1987)] experiment, which showed that jnd's are independent of the slope of the loudness function was replicated. Threshold shifts and altered loudness-balance functions for 1-kHz tones were produced by using backgrounds of narrow- or wideband noise. The two types of background noise produced intersecting points on loudness-balance functions at which intensity jnd's were obtained. Intensity jnd's were also obtained at equal-loudness levels (corresponding to 30, 40, 50, and 60 dB SL in the unmasked ear) under each of the two noise conditions and in quiet. The results indicate that tones of equal loudness produce approximately equal jnd's and that there is no apparent relation between the slope of the loudness-balance functions and the size of the intensity jnd.
