“…The exponent of loudness as a function of sound pressure is typically steeper for magnitude production than it is for magnitude estimation ( Reynolds and Stevens, 1960 ), i.e., a difference of less than 10 dB is required to double loudness. Stevens and co-workers found exponents of 0.7, corresponding to 9 dB being required to double loudness, in magnitude-production tasks ( Stevens and Guirao, 1962 ; Stevens and Greenbaum, 1966 ; Figure 5 ); Hellman (1981) reported an exponent of 0.81 (7 dB to double loudness) for a 1-kHz pure tone. Teghtsoonian and Teghtsoonian (1978) found that the exponent depended on the range of magnitudes that is presented.…”

Continuous magnitude estimation and continuous cross-modality matching with line length can efficiently track the momentary loudness of time-varying sounds in behavioural experiments. These methods are known to be prone to systematic biases but may be checked for consistency using their counterpart, magnitude production. Thus, in Experiment 1, we performed such an evaluation for time-varying sounds. Twenty participants produced continuous cross-modality matches to assess the momentary loudness of fourteen songs by continuously adjusting the length of a line. In Experiment 2, the resulting temporal line length profile for each excerpt was played back like a video together with the given song and participants were asked to continuously adjust the volume to match the momentary line length. The recorded temporal line length profile, however, was manipulated for segments with durations between 7 to 12 s by eight factors between 0.5 and 2, corresponding to expected differences in adjusted level of −10, −6, −3, −1, 1, 3, 6, and 10 dB according to Stevens’s power law for loudness. The average adjustments 5 s after the onset of the change were −3.3, −2.4, −1.0, −0.2, 0.2, 1.4, 2.4, and 4.4 dB. Smaller adjustments than predicted by the power law are in line with magnitude-production results by Stevens and co-workers due to “regression effects.” Continuous cross-modality matches of line length turned out to be consistent with current loudness models, and by passing the consistency check with cross-modal productions, demonstrate that the method is suited to track the momentary loudness of time-varying sounds.

Psychophysical scaling refers to the process of quantifying psychological events, especially sensations and perceptions. Scaling requires both a set of empirical operations and a theoretical framework to derive the quantitative values or representations. The chapter treats scaling as it is accomplished through discrimination, partition, and magnitude methods, in each case considering how the relevant data are obtained, how the scales depend on the particular theoretical assumptions, and the extent to which findings are compatible with those assumptions. With partition and magnitude methods in particular, it is important to consider the ways that nonlinear response transformations may intervene between underlying perceptual scales and overt responses; within this framework, the chapter reviews the experimental and methodological variables that affect overt psychophysical responses, as well as theories that seek to validate various approaches to scaling. Detailed examples are given of the design and analysis of two experiments, one of which used a partition method (graphic rating) and the other a magnitude method (magnitude estimation), to study binaural summation of loudness, thereby illuminating many of the important experimental and theoretical issues while at the same time revealing the pragmatic value of using scaling methodology to study sensory and perceptual processes.
