A Scatter plot of the effective target attenuation in the two-object vowel judgments (abscissa) vs in the tone judgments (ordinate). The solid line shows where results would fall if energy conservation holds. The dotted line shows the expected relationship if target amplitude, rather than energy, trades (corresponding to a loss of 3 dB of the target energy). B Lost target energy calculated as the difference between the physical target energy and the sum of the target energy perceived in the tones and vowel.
