The estimation of harmonic to noise ratio (HNR) in transmitted sound signals with a wavelet transform was proposed. When subjects phonate sustained vowels in breathy, falsetto, leakage and pressed mode in normal loudness, the HNR in the human voice and transmitted sound signals was estimated and compared. The results indicated that the HNR in transmitted sound signals could accurately image vocal fold vibration characteristics. It would be a useful measurement for clinical laryngeal disease diagnosis.
