对音乐速度差别感受阈限的研究

本实验用最小变化法测量音乐速度差别感受阈限。采用两段速度分别为=80和=120的标准音乐材料（教堂歌曲《Amazing Grace》和贝多芬《G大调小步舞曲》，Midi格式），用Finale Notepad 2008进行编辑，每一段标准音乐有10段速度渐变的对比刺激（渐变节拍分别为2和4），用Windows Media Player 11播放器播放标准音乐和对比音乐，让被试判断两者的速度有无差异。结果表明，对速度差别的感受阈限随着标准音乐材料的速度增加而提高，差异显著，验证了费希纳-韦伯定律；同时对人们生活．作曲家创作具有指导意义。

Measuring the Differential Threshold on the Speed of the Music

This experiment is based on the method of minimal change way to measure the difference threshold by the speed of the music.The materials are in the use of the two kinds of the standard music,speed of =80 and =120(choir Amazing Grace and Beethoven's Minuet in G,all in Midi files),by using Finale Notepad 2008 to edit and the Windows Media Player 11 to play.The compared materials are 10 pieces of the different speed but the same tune to each piece of the standard materials,descending or ascending 2 beats for A...
