The influence of fundamental frequency on perceived duration: A replication study


The following study examines the relation between perceived duration and the intensityand fundamental frequency of sounds. Sounds with higher fundamental frequency (the lowestfrequency of a periodic waveform) and greater intensity are judged to have longer duration.However, it is not known if fundamental frequency, intensity, or both affect the perceivedduration, and to what extent. The purpose of this study is to find out the variance in contributionof both fundamental frequency and intensity to perceived duration through two forced choicetasks. Through replication, we found that fundamental frequency does in fact have a significantpositive effect on perceived duration while intensity did not. Future research may focus ontesting these results among different language groups, and applying these results to anunderstanding of communication and language.
