论文摘要
面具言语言语，使沟通更加困难，尤其是对于听力损失的人而言。这项研究研究了使用头部形的扬声器和现场演讲者，研究了不同面膜，包括医疗，布和透明口罩在内的不同面膜所引起的声学衰减。结果表明，所有口罩都会衰减1 kHz以上的频率，这是说话者面前最大的衰减，并且在掩模类型之间，尤其是带有不同材料和编织的布面具之间存在实质性差异。与医用面具和布面具相比，透明面具的声性能较差。大多数口罩对翻领麦克风的影响很小，这表明现有的声音增强和辅助聆听系统可能有效地与口罩交流。
Face masks muffle speech and make communication more difficult, especially for people with hearing loss. This study examines the acoustic attenuation caused by different face masks, including medical, cloth, and transparent masks, using a head-shaped loudspeaker and a live human talker. The results suggest that all masks attenuate frequencies above 1 kHz, that attenuation is greatest in front of the talker, and that there is substantial variation between mask types, especially cloth masks with different materials and weaves. Transparent masks have poor acoustic performance compared to both medical and cloth masks. Most masks have little effect on lapel microphones, suggesting that existing sound reinforcement and assistive listening systems may be effective for verbal communication with masks.
