In environmental psychoacoustics, experimental sounds are taken from recordings of real-life situations. This makes stimulus selection an important element of experimental design. For example, the sound level of road-traffic noise close to a major road may vary considerably depending on the number of vehicles that passes by. Thus, a psychoacoustical evaluation of the loudness or annoyance of the road-traffic noise would depend on which samples of the noise were presented in a listening experiment. Therefore, a method was developed for representative selection of experimental sounds from recordings in real-life situations. The method has been applied in research on auditory change caused by noise mitigation and in research on psychophysical relationships for loudness of road-traffic noise. It is argued that for many psychoacoustical problems, the ecological validity gained by representative selection outweighs the loss in internal validity caused by the reduced control of specific acoustical variables of the experimental sounds.
