Arguments for the decrease 47% state that the stronger impact of face masks on the infectious in Jena might thereby partly be pushed by a Hawthorn impact.

The working doc was uploaded as a preprint in, and improvements incorporating extra proof have been added.

Simulation system for airborne transmission of virus droplets/aerosols. A test chamber for airborne transmission experiments was constructed in a BSL3 facility, and two mannequin heads have been placed going through each other. One mannequin head was related to a customized compressor nebulizer and exhaled a mist of virus suspension via its mouth to mimic a viral spreader. The different model head was related to a synthetic ventilator via a virus particle collection unit. Tidal breathing, performed by the artificial ventilator, was set to a lung air flow rate consultant of a gentle state in adults (i.e., 0.5 liter of tidal volume, a respiratory rate of 18 breaths/min, and a 50% fuel change fee). Face masks have been hooked up to the mannequin heads according to each producer’s instructions.
