Sound Barrier

  1. Nov 13, 2007 #1
    A question:

    When you cross the speed of sound you get to this sound barrier.

    So basically you can only hear sounds that are coming from ahead in 179° angle?

    But here is a question:

    Suppose someone behind me has made a sound, so I hear it once. Then I cross the sound barrier and I am "chasing" this sound ahead of me. Will I hear this sound again then? The wavelength will be very high I guess, which means it's a very low frequent sound.

    Just want some clarification, because Doppler doesn't say anything about "chasing sounds".

    I would say this formula:

    f'=f(v-c)/v

    v is your speed 360 m/s
    c is the speed of that sound someone made = 330 m/s
