The widespread use of face coverings during the COVID-19 pandemic has created communication challenges for many individuals, particularly for those who are deaf or hard of hearing and for those who must speak through masks in suboptimal conditions. This study includes some newer mask options as well as transparent masks to help those who depend on lipreading and other facial cues. The results corroborate earlier published results for non-transparent masks, but transparent options have greater attenuation, resonant peaks, and deflect sounds in ways that non-transparent masks do not. Although transparent face coverings have poorer acoustic performance, the presence of visual cues remains important for both verbal and non-verbal communication. Fortunately, there are creative solutions and technologies available to overcome audio and/or visual barriers caused by face coverings.
在 COVID-19 大流行期间，口罩的广泛使用给许多人带来了沟通挑战，特别是对于那些失聪或听力受损的人，以及那些必须在不理想条件下通过口罩说话的人。本研究包括一些较新的口罩选择，以及透明口罩，以帮助那些依赖唇读和其他面部线索的人。研究结果与之前发表的非透明口罩的结果相符，但透明口罩的衰减更大，共振峰更多，并以非透明口罩所没有的方式使声音偏离。尽管透明面罩的声学性能较差，但视觉提示对于言语和非言语交流仍然很重要。幸运的是，有创造性的解决方案和技术可以克服口罩造成的音频和/或视觉障碍。
