声学与我们生活紧密联系,声音是怎样产生的?声音的传播速度与哪些因素有关?人能听到声音的条件是什么?声音中“高低”和“大小”什么区别?城市如何减弱噪声?等问题都离不开系统掌握声学.本文着重分析学习声学中必须突破几道坎,以期在应用声学中不至于出错.一、“声音的产生”和“声音的传播”不同声音是由发声体的振动产生的,一切发声体都在振动,振动停止,发声停止;而声音是以波的形式向外传播,或者说声音
Acoustics and our lives are closely linked, how is the sound produced? What is the speed of sound transmission and what factors? Can people hear the sound conditions? What is the difference between the sound “” and “size”? Noise reduction, and other issues are inseparable from the system to master the acoustics.This paper focuses on the analysis of learning acoustics must break through a few hurdles, in the application of acoustics will not go wrong .. First, “sound generation ” and “sound transmission ”The different sounds are generated by the vibration of the sounding body. All the sounding bodies are vibrating, the vibration stops, and the sound stops. The sound is spread out in the form of waves, or the sound
