Abstract:
The Effect of Treble and Bass on Musical Notes
Nathan G.
The purpose of this experiment was to determine differences in height and width of musical notes with different levels of bass and treble applied to them. To carry out this experiment, the notes that were being tested were played on a guitar, that went through an ampliphier, and then directly into the computer where the sound waves were displayed up on the screen graphically showing the actual sound waves before and after the note was played. The computer allowed the height and width of the notes played to be measured. To allow for both bass and treble notes to be tested, the different notes being tested had either all bass and no treble, or the opposite. The level of both treble and bass was varied by the knobs on the amplifier allowing the bass or treble to be on a scale of 0 to 10 (0 being the lowest). During the time when treble and bass were being tested, the height and width of the sound waves were being measured so that after the testing, averages could be made on all the notes in centimeters. The averages later determined the defferences on the notes more bass or more treble.
After the completion of the experiment, it was determined that the notes with more bass had the wider (2.02cm.) and taller (2.02cm.) sound waves. The notes with more treble had an average height of 1.76 cm. and an average width of .5 cm.
