Abstract
A method for synthesizing an engine sound includes outputting a first synthesized engine sound, obtaining a change in a first surrounding noise environment, learning an artificial neural network to obtain first masking level information corresponding to the obtained change in the first surrounding noise environment, generating a second synthesized engine sound by correcting the first synthesized engine sound based on the obtained first masking level information, and outputting the generated second synthesized engine sound.
