Abstract
A preliminary study reported the results of equal-loudness-level contours (ELLC) of older adults, which was measured by magnitude estimation (ME) method. The geometrical mean of the two numbers assigned to each stimulus was first calculated to obtain a magnitude estimate of individual listeners. ME method was produced ELLCs efficiently with precision comparable to those of other psychophysical methods, such as the method of constant stimuli and the bracketing method. The results of the study indicated that the ME method was able to yield ELLCs comparable to those in the ISO standard obtained with other measurement methods. ELLCs for numerous older adults were obtained in a short time using the ME method.
