声学是研究弹性媒质(气体,液体和固体)中所传播的机械振动的科学。人类在很早时期就注意到音乐的规律,声学就是从音乐的研究开始的。在尚书中说:“夔曰:于,予击石拊石,百兽率舞”。这大概就是石器时代音乐的开始吧。在我国,很早就有了五音,在战国时,管子中正式记载“三分损益法”(就是“以宫数三分益一为征,商数三分益一为羽……”),并得到十二律(把一个倍频程分为十二个半音)。在早期,印度用二十二律,阿拉伯用十七律。希腊最早只有三音,到特宾德儿和皮札果拉斯时才发展为七音,皮札果拉斯用三分损益法算音程。管子比皮札果拉斯要晚400年,但是在希腊,三 Acoustics is the science that studies the mechanical vibrations propagating in elastic media (gases, liquids, and solids). At a very early time, human beings noticed the law of music. Acoustics began with the study of music. In the book, said: “夔 said: in, to hit rock stone, the rate of dance of the hundred animals.” This is probably the beginning of the Stone Age music. In our country, there were five voices very early. In the Warring States period, Guanzhong officially recorded the “one-third profit and loss method” (that is, And get twelve laws (divide one octave into twelve semitones). In the early days, India used twenty-two laws and Arabs used seventeen laws. Greece, the earliest only three tones, to Tedder and Pedro Razs only developed into seven-tone, Pipi Jazzlas three-point loss method to calculate the range. The tube was 400 years later than the Pinot Noir, but in Greece, three
