Abstract: An apparatus for evaluating sound quality and a method thereof may include generating an original sound, measuring a test sound generated from a subject of sound quality evaluation, analyzing a signal of the test sound measured according to a time domain, generating a plurality delay signals that are delayed from the signal of the time domain by one period, determining a degree of matching by matching the signal of the time domain to each delay signal, determining whether a white nose is occurred based on the degree of matching, and outputting the status of the white noise on the subject of the sound evaluation. The signal of the test sound may be analyzed according to a frequency domain, and a degree of occurrence of buzz and rattle is determined based on a fundamental frequency of the frequency domain and a plurality of Harmonics corresponding to the frequency domain.
