摘要： A vehicle that selectively provides important sound to an occupant includes: a microphone configured to receive a noise sound; a speaker; a storage configured to store a plurality of sound waveforms and a warning sound source corresponding to each sound waveform of the plurality of sound waveforms; and a controller configured to generate a noise canceling signal based on the noise sound, control the speaker to output a noise canceling sound corresponding to the noise canceling signal, compare a waveform of the noise sound with the plurality of sound waveforms when a sound pressure level of the noise sound is greater than a threshold value, and when the waveform of the noise sound matches any sound waveform of the plurality of sound waveforms, and control the speaker to play a warning sound source corresponding to the sound waveform matching the noise sound.
