Turn on the function generator and oscilloscope, and adjust the dial on the function generator to produce a wave with 5 kHz frequency. The speaker connected to the function generator should produce a steady pitch that sounds like an alarm. Two 5kHz waves that are out of phase with one anoth...
What is the difference between the red shift and Doppler effect? What is the frequency of light? How do you find the frequency of a tone given a period of 50 milliseconds? Briefly explain the frequency theory of hearing. Is heat an electromagnetic wave?

This invention is an apparatus for substantially changing the length and amplitude of sound waves. It is an object of the invention to very materially reduce or eliminate the objectionable wave impulses set up by operation of various machines, especially such as the more powerful pressure......
PURPOSE: A sound wave escapement device is provided to generate the optimum frequency appropriate for an application object and to improve an escapement effect by changing a wave sound frequency through simple manipulation. CONSTITUTION: A sound wave escaping device is made up of a driver(11) for...
之后就是验证这个是不是wave文件了,看代码1,应该不难理解,然后获取wav format,其中包括了音频格式,声道数量,采样率,字节率,采样点位数等等,代码3验证它是否采用PCM编码,实际上绝大多数都是采用这种编码格式,要是觉得自己NB的话,甚至可以自己写一个 汇蓝鸟 麻婆豆腐 11 最后找data块,wav格式在源代码发布完毕后...
Doppler effect, the apparent difference between the frequency at which sound or light waves leave a source and that at which they reach an observer, caused by relative motion of the observer and the wave source. It was first described (1842) by the Austr
