A politician is standing in front of a sound source playing a 440 Hertz tone. The politician, disturbed by a large hamster, starts moving to- wards the sound source. On average, a human can perceive a difference in frequency of about 0.5%. By how many Hz does the frequency have to shift (due to the Doppler effect) for the politician to notice?

How fast, in meters/second, does one have to move to perceive a Doppler shift of 0.5%. Is this a (typical) walking speed, running speed, biking speed, or driving speed?
I really need clarification on the question! What does "difference in frequency of about 0.5%" mean? As in 0.5% from the sound frequency from the source? or is it something else? I found a solution somewhere but it didn't make sense to me. If anyone can help me with it that would be great!
