Wall Design Centers Experience of Deaf and Hard-of-Hearing Individuals #ASA190

In many types of rooms, sound reflecting off multiple walls muddies conversation, making it harder to understand. So, to control how sound travels in a room, researchers developed a patterns wall to improve the listening experience of deaf and hard-of-hearing individuals. They first conducted acoustic simulations to study how different surface textures influenced speech clarity. Then they designed and 3D-printed "tiles" that can be linked together to fit different room shapes and sizes. Po-Chun
