Hi! I'm in charge of the animation of the guided tour industry in Brussels. The issue is : speaking loud & audible with a mask is not ideal for tours even if you are 6 (usually a guided tour is up to 25 people). I was wondering if you heard about initiatives regarding social distancing between transmitter and receivers, in the context of tour guides (app for wireless audio systems; touchless materials, whispers-audio-systems,...)? In the context of the crisis, I think such technology could be used for many other citizen activity (teacher in a classroom, public (physical) presentation,...).
wireless audio systems - leisure social distanciation
