Variation of the acoustic parameter harmonic-to-noise ratio in relation to different background noise levels.

CONCLUSIONS: The background noise of the premises where the voice recording for the acoustic analysis is performed, influences the value of the acoustic parameter HNR, which decreases as the background noise of the premises increases. It is recommended that the background noise level should not exceed 43.8dB(A). PMID: 32828526 [PubMed - as supplied by publisher]
