在八十年代的文化生活中,立体声录音和放音已经深入到家庭,成为人们欣赏音乐的应用技术. 立体声,顾名思义就是在录、放音技术中,正确体现声音信号的立体感、空间感和方位感,这是人们在音乐厅中聆听音乐所感受到的信息.远在十九世纪末,著名物理学家、现代声学理论奠基人之一瑞利在他的“声学理论”一书中,就对人们听闻方位感的感知机理作了较完整的叙述.但直到三十年代初,立体声才有

In the cultural life of the 1980s, stereo recording and playback have been deepened into the family and become the application technology of people’s enjoyment of music.As the name suggests, stereoscopic sound, stereo recording and playback technology correctly reflect the three-dimensional sense of the sound signal and the sense of space This is the message that people feel when they listen to music in the concert hall.As far as the end of the nineteenth century, Rayleigh, a famous physicist and founder of modern acoustics theory, was right in his book “Theory of Acoustics” People perceive a more complete description of the perception mechanism of orientation, but until the early 1930s, stereo had
