[QUOTE="Phylosopher, post: 6014616, member: 599850"] I didn't understand the second part of the question clearly. But I think the overall question is clear to me. I think you know how to use Doppler effect equation, otherwise you won't post the question ^^'. But it seems that you don't know were to start. Before reading the Spoiler, I encourage you to think hard on analysing the problem! I know it is sometimes hard. Start with asking what do you want? Then what do you know? and then how can you solve this problem? -- Don't be afraid of searching on the internet. If you failed after a long time, look at the spoiler.[Spoiler] First, you need to know how much can a human hear! The human hearing ranges in frequency between 20Hz and 20KHz (Above or lower than this is impossible to hear). Second, you need to make the speaker emit one type of frequency (Otherwise the experiment is flawed, since each frequency can be shifted out of the hearing range with a different "difference") Third, now just use Doppler equation for sound ->> [URL='https://en.wikipedia.org/wiki/Doppler_effect']Here[/URL], If you do not remember the meaning of the equation. Read the General section from Wiki. [/Spoiler] Edit: Edited the wiki link [/QUOTE]
