The Influence of Sound Processing on Listeners' Program Choice in Radio Broadcasting
Many opinions on broadcast sound processing are founded on tacit assumptions about certain effects on listeners. However, those have lacked support by internally and ecologically valid empirical data so far. Thus, under largely realistic conditions it has been experimentally investigated to what extent broadcast sound processing influences listeners’ program choice. Technical features of stimuli, socio-demographic data of the test persons, and data of listening conditions have been additionally collected. In the main experiment, subjects were asked to choose one out of six audio stimuli varied in content and sound processing. The varied sound processing caused marginal and statistically not significant differences in frequencies of program choice. By contrast, a subsequent experiment enabling a direct comparison of different sound processings of the same audio content yielded distinct preferences for certain sound processings.
