背景：成功的沟通在医疗环境中是必要的。然而，医院、手术室和牙科诊所中存在的噪声可能对卫生保健人员和患者准确理解信息产生有害影响。外科口罩和听力损失的存在可能会进一步影响言语知觉。目的：评估外科口罩是否对听力正常和听力受损的听众在牙科诊所噪音存在或不存在的情况下进行言语刺激时的言语理解产生影响。研究设计：在这项准实验性的横断面研究中，参与者根据听力灵敏度被分为两组。共有31名成年人参与了这项研究（1名谈话者，15名听力正常的听众，15名听力障碍者）。听力正常组在250到8000 Hz的倍频程频率下的阈值为25 dB HL或更好，而听力损失组在相同倍频程频率下的阈值等于或低于25 dB HL的听力损失程度和结构不同。数据收集和分析：从连接语音测试（CST）中选择的列表在存在和不存在外科口罩的情况下进行数字记录，然后在四种条件下呈现给听众：结果：噪声环境中有无掩蔽声对语音刺激的频谱分析有显著性差异，噪声环境中无掩蔽声对语音刺激的频谱分析有显著性差异。然而，外科口罩的存在并没有对听力正常或听力受损组的言语理解产生不利影响。牙科办公室的噪音有显着的影响，两个groups.Conclusions的言语理解：这些研究结果表明，外科口罩的存在并没有负面影响言语理解。然而，噪音的存在确实对言语感知产生了有害影响，需要在卫生保健环境中进一步关注。
Background: Successful communication is necessary in health-care environments. Yet the presence of noise in hospitals, operating rooms, and dental offices may have a deleterious effect on health-care personnel and patients understanding messages accurately. The presence of a surgical mask and hearing loss may further affect speech perception.Purpose: To evaluate whether a surgical mask had an effect on speech understanding for listeners with normal hearing and hearing impairment when speech stimuli were administered in the presence or absence of dental office noise.Research Design: Participants were assigned to one of two groups based on hearing sensitivity in this quasi-experimental, cross-sectional study.Study Sample: A total of 31 adults participated in this study (1 talker, 15 listeners with normal hearing, and 15 with hearing impairment). The normal hearing group had thresholds of 25 dB HL or better at the octave frequencies from 250 through 8000 Hz while the hearing loss group had varying degrees and configurations of hearing loss with thresholds equal to or poorer than 25 dB HL for the same octave frequencies.Data Collection and Analysis: Selected lists from the Connected Speech Test (CST) were digitally recorded with and without a surgical mask present and then presented to the listeners in four conditions: without a mask in quiet, without a mask in noise, with a mask in quiet, and with a mask in noise.Results: A significant difference was found in the spectral analyses of the speech stimuli with and without the mask. The presence of a surgical mask, however, did not have a detrimental effect on speech understanding in either the normal-hearing or hearing-impaired groups. The dental office noise did have a significant effect on speech understanding for both groups.Conclusions: These findings suggest that the presence of a surgical mask did not negatively affect speech understanding. However, the presence of noise did have a deleterious effect on speech perception and warrants further attention in health-care environments.
