Preferences in the spectrum of electronically reproduced sound, as expressed by learners in grades I to XII
MetadataShow full item record
AbstractThe primary focus in this exploratory study was directed at the frequency range students in school grades prefer when they are listening to speech or music being reproduced through electronic reproduction devices. Two hundred forty students from grades one to twelve were encouraged to select volume, bass, and treble settings while listening to (1) speech and (2) music when (1) volume was given and when (2) volume was free. Ten sets of data were recorded for each child and ten null hypotheses were formulated, stating that no differences exist between grades and within grades, in preferred settings. The four treatments were administered in empty classÂrooms in three schools. The children selected preferred settings of volume, bass, and treble by manipulating knobs on an electronic sound reproduction device. The first and third treatments were administered while the subject listened to a selection from Winnie-the-Pooh. The second and fourth treatments were administered while the subject listened to the theme of the television program Bonanza. To test the Null hypotheses, aô€ ³ VI Anova 3-factor experiment with repeated measures was used for between-group analysis; a 4-way factorial design was used for withingroup analysis. The results show that there is no difference between grades in the selected frequency ranges for speech. However, there is a difference between grades for music. Within grades there are differences in both the selected settings for speech and music.
