Fiscal 2021 Ventilation status survey and mask wear verification experiment report at the time of the event sponsored by the Ota City Cultural Promotion Association

The Ota Ward Cultural Promotion Association is important to prevent the spread of new coronavirus infection at the "Opera Gala Concert: Again" held at Ota Ward Hall Aplico on Sunday, August 2021, 8. We investigated whether the element [ventilation] was sufficiently performed in the hall.
Continuing from last year, we asked Mr. Tomoaki Okuda, a professor of the Department of Applied Chemistry, Keio University, to conduct the survey.
In addition, at the time of holding this performance, we also verified in advance the preventive effect of wearing a mask on the chorus.

We have compiled a report on the above survey and will publish it.
