    • 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.
    • 用于评估声音质量的装置及其方法可以包括产生原始声音,测量从音质评估对象产生的测试声音,分析根据时域测量的测试声音的信号,产生多个延迟信号, 从时域的信号延迟一个周期,通过将时域的信号与每个延迟信号进行匹配来确定匹配度,基于匹配程度来确定是否发生白鼻子,并且输出状态 白噪声对声音评估的主题。 可以根据频域分析测试声音的信号,并且基于频域的基频和对应于频域的多个谐波来确定嗡嗡声和咔嗒声的发生程度。
