Abstract
Here we present a device that suppresses transfer of aerosol between nearby seating areas through the use of optically transparent, sound transmitting barriers and HEPA fan filter unit (FFU). A potential application of this device is to lower the risk of respiratory disease transmission in face-to-face, maskless meetings between individuals in a university setting. We evaluate overall aerosol transmission between users of the device. This is done for two different physical settings: a large space, such as a library, and a small space, such as an enclosed study room. We find that the device can provide lower aerosol transmission compared to the typical transmission between two individuals wearing surgical face masks separated by six feet.

Talking is of particular concern for transmission of respiratory diseases as the output of viral particles from an infected person can be an order of magnitude or more greater compared to only breathing [10]
The device presented in this work solves this problem by adding an HEPA fan filter unit (FFU) close to the users which actively drags the air in and filters the aerosols before it mixes with room air
