To compare range effects in loudness scaled with magnitude estimation (ME) and the Borg CR100 (centiMax) Scale®, a classroom experiment with a total of 53 subjects (27+26) was conducted. Two conditions with a wide and a narrow stimulus range were used (Group A: ME-narrow; ME-wide; CR-wide; CR-narrow; and Group B: ME-wide; ME-narrow; CR-narrow; CR-wide). Average exponents obtained were: n(ME-narrow) = 0.69; n(ME-wide) = 0.47; n(CR-narrow) = 0.48; n(CR-wide) = 0.43 for group A; and: n(ME-narrow) = 0.70; n(ME-wide) = 0.49; n(CR-narrow) = 0.66 ; n(CR-wide)= 0.46, for group B. For ME, the range effect was significant for both groups, but for CR100 a significant range effect was only obtained for group B. These results suggest that the CR100 is less sensitive than ME to context effects related to stimulus range.
