Objective.本研究的目的是探讨外科口罩对一些声乐参数，如F0，声音强度，抖动，微光和谐波噪声比的影响，以了解外科口罩如何影响成人的声音和言语交流。该研究在选定的60名健康受试者中进行。所有受试者都接受了训练，以最大发声时间（MPT）的对话语音强度发出持续/a/的语音样本，戴上外科口罩，然后不戴外科口罩。语音样本直接记录在Praat.Results.掩蔽和非掩蔽条件之间的任何声学参数均无统计学显著差异。65%的受试者戴外科口罩时声音强度无显著下降。在观察到的、提取的佩戴和不佩戴外科口罩的所有声学语音参数之间进行的统计学比较没有揭示任何显著的统计学差异。大多数受试者在戴上外科口罩后，所测量的声音强度下降。我们的结论是，戴口罩可能会引起无意识地需要增加发声努力，随着时间的推移，导致发展为功能性发声障碍的风险更大。强度的降低也会影响社会交往和言语可听度，特别是对于听力损失的人。
Objective. The purpose of our study was to investigate the impact of surgical mask on some vocal parameters such as F0, vocal intensity, jitter, shimmer and harmonics-to-noise ratio in order to understand how surgical mask can affect voice and verbal communication in adults.Methods. The study was carried out on a selected group of 60 healthy subjects. All subjects were trained to voice a vocal sample of a sustained /a/, at a conversational voice intensity for the Maximum Phonation Time (MPT), wearing the surgical mask and then without wearing the surgical mask. Voice samples were recorded directly in Praat.Results. There were no statistically significant differences in any acoustic parameter between the masked and unmasked condition. There was a non-significant decrease in vocal intensity in 65% of the subjects while wearing a surgical mask.Conclusions. The statistical comparison carried out between all the acoustic voice parameters observed, extracted wearing and not wearing a surgical mask did not reveal any significant statistical difference. Most of the subjects, after wearing the surgical mask, presented a decrease in vocal intensity measured. Our conclusion was that wearing a mask is likely to induce the unconscious need to increase the vocal effort, resulting over time in a greater risk of developing functional dysphonia. The reduction of intensity can affect also social interaction and speech audibility, especially for individuals with hearing loss.
