Participants rated the question using a binary forced choice as either YES or NO. The mean age of participants consenting to the study was 30.9 ± 6.3 SD years,with male predominance (%). Among the choice of use of face mask, 76.35% used surgical mask, 14.77% used KN95 and 8.86% used cloth masks. 15 questions were divided in 5 categories; analysis showed that majority of questions had an affirmative "yes" response. This results of this study indicated that the sudden change in the existing communication situation due to use of face masks in the clinical setup affected interpersonal communication among healthcare workers and with patients, which may also have a bearing on both patient and clinician well being and could have a significant economic impact on health care systems globally. These results provide information about the clinical strain introduced from use of face masks in healthcare settings. Overall, results showed that in healthcare settings, there is increased cognitive load and listening effort for patients and health care providers, as well as changes in clinical efficiency for providers when utilizing masks. These effects are often greater with hearing loss.
