Question:
Is tempo affected by the Doppler effect ?
for ex:
would the beat of music be changed as the source approaches or recedes
from the observer?
Replies:
Absolutely. The tempo would speed up as the source approaches you.
Dr. Bradburn
Yes. It's just like spinning a record (remember records?) faster on the
turntable.
Tim Mooney
Yes, in the same way and for the same reason that the pitch is affected, the
tempo is also affected. If the source of music moves away from the
listener, the beat appears to go slower then when the source of the music
moves away.
