I've got an hw problem that I just can't get, here it is:
Finally, your friend's twin engine jet airplane lands. As it stands on the runway, you hear the sound of the engines getting louder and softer, rhythmically once every 2.1 s. The average frequency you hear is 3300 Hz. What are the differences between the average frequency and the individual frequencies of the sounds from each engine?
I dont even know where to start, any help would be great, Thanks
