1. An urban air mobility (UAM) noise reduction system comprising:
a UAM configured to detect and to provide rotation per minute (RPM) information of a propeller and location coordinate information;
a noise canceling device configured to predict a noise canceling sound wave amplitude on the basis of the RPM information of the propeller and the location coordinate information received through the UAM and to output a noise canceling sound wave corresponding to the predicted noise canceling sound wave amplitude to the UAM; and
a verifier configured to verify the noise cancelling sound wave amplitude and to manage the verified noise canceling sound wave amplitude by storing the verified noise canceling sound wave amplitude in a database.
