Overall noise loudness is judged retrospectively rather than averaged moment to moment

Evidence

In psychoacoustic experiments, noise immissions are frequently assessed as follows: the subjects are presented stimuli of e.g. 15 minutes duration which include a soft background noise (e.g. road-traffic noise of 40 dB(A)) plus several louder events (e.g. fly-overs of aircraft). During the presentations, the subject has to indicate the instantaneous loudness by varying the length of a bar presented on the monitor of a PC. After the experiment is over (e.g. after 15 minutes) the subject has to fill in a questionnaire and is asked - among others - to indicate the overall loudness of the preceding 15 minutes by marking the length of a line. — Professor Dr.-Ing.

  • QUESTION: Does overall loudness judgment correlate with peak rather than average because of peak-end rule cognition? Worth comparing to Kahneman’s peak-end research.
  • XREF: Connects to Kahneman’s peak-end heuristic on retrospective evaluation of experiences.
